-// Overview:
-// base::BindOnce() and base::BindRepeating() are helpers for creating
-// base::OnceCallback and base::RepeatingCallback objects respectively.
-//
-// For a runnable object of n-arity, the base::Bind*() family allows partial
-// application of the first m arguments. The remaining n - m arguments must be
-// passed when invoking the callback with Run().
-//
-//   // The first argument is bound at callback creation; the remaining
-//   // two must be passed when calling Run() on the callback object.
-//   base::OnceCallback<long(int, long)> cb = base::BindOnce(
-//       [](short x, int y, long z) { return x * y * z; }, 42);
-//
-// When binding to a method, the receiver object must also be specified at
-// callback creation time. When Run() is invoked, the method will be invoked on
-// the specified receiver object.
-//
-//   class C : public base::RefCounted<C> { void F(); };
-//   auto instance = base::MakeRefCounted<C>();
-//   auto cb = base::BindOnce(&C::F, instance);

+// RETURN TYPES
+//
+// Though Bind()'s result is meant to be stored in a Callback<> type, it
+// cannot actually return the exact type without requiring a large amount
+// of extra template specializations. The problem is that in order to
+// discern the correct specialization of Callback<>, Bind would need to
+// unwrap the function signature to determine the signature's arity, and
+// whether or not it is a method.
+//
+// Each unique combination of (arity, function_type, num_prebound) where
+// function_type is one of {function, method, const_method} would require
+// one specialization.  We eventually have to do a similar number of
+// specializations anyways in the implementation (see the Invoker<>,
+// classes).  However, it is avoidable in Bind if we return the result
+// via an indirection like we do below.
+//
+// TODO(ajwong): We might be able to avoid this now, but need to test.
+//
+// It is possible to move most of the COMPILE_ASSERT asserts into BindState<>,
+// but it feels a little nicer to have the asserts here so people do not
+// need to crack open bind_internal.h.  On the other hand, it makes Bind()
+// harder to read.

+// This defines a set of argument wrappers and related factory methods that
+// can be used specify the refcounting and reference semantics of arguments
+// that are bound by the Bind() function in base/bind.h.
+//
+// It also defines a set of simple functions and utilities that people want
+// when using Callback<> and Bind().
+//
+//
+// ARGUMENT BINDING WRAPPERS
+//
+// The wrapper functions are base::Unretained(), base::Owned(), base::Passed(),
+// base::ConstRef(), and base::IgnoreResult().
+//
+// Unretained() allows Bind() to bind a non-refcounted class, and to disable
+// refcounting on arguments that are refcounted objects.
+//
+// Owned() transfers ownership of an object to the Callback resulting from
+// bind; the object will be deleted when the Callback is deleted.
+//
+// Passed() is for transferring movable-but-not-copyable types (eg. scoped_ptr)
+// through a Callback. Logically, this signifies a destructive transfer of
+// the state of the argument into the target function.  Invoking
+// Callback::Run() twice on a Callback that was created with a Passed()
+// argument will CHECK() because the first invocation would have already
+// transferred ownership to the target function.
+//
+// ConstRef() allows binding a constant reference to an argument rather
+// than a copy.
+//
+// IgnoreResult() is used to adapt a function or Callback with a return type to
+// one with a void return. This is most useful if you have a function with,
+// say, a pesky ignorable bool return that you want to use with PostTask or
+// something else that expect a Callback with a void return.
+//
+// EXAMPLE OF Unretained():
+//
+//   class Foo {
+//    public:
+//     void func() { cout << "Foo:f" << endl; }
+//   };
+//
+//   // In some function somewhere.
+//   Foo foo;
+//   Closure foo_callback =
+//       Bind(&Foo::func, Unretained(&foo));
+//   foo_callback.Run();  // Prints "Foo:f".
+//
+// Without the Unretained() wrapper on |&foo|, the above call would fail
+// to compile because Foo does not support the AddRef() and Release() methods.
+//
+//
+// EXAMPLE OF Owned():
+//
+//   void foo(int* arg) { cout << *arg << endl }
+//
+//   int* pn = new int(1);
+//   Closure foo_callback = Bind(&foo, Owned(pn));
+//
+//   foo_callback.Run();  // Prints "1"
+//   foo_callback.Run();  // Prints "1"
+//   *n = 2;
+//   foo_callback.Run();  // Prints "2"
+//
+//   foo_callback.Reset();  // |pn| is deleted.  Also will happen when
+//                          // |foo_callback| goes out of scope.
+//
+// Without Owned(), someone would have to know to delete |pn| when the last
+// reference to the Callback is deleted.
+//
+//
+// EXAMPLE OF ConstRef():
+//
+//   void foo(int arg) { cout << arg << endl }
+//
+//   int n = 1;
+//   Closure no_ref = Bind(&foo, n);
+//   Closure has_ref = Bind(&foo, ConstRef(n));
+//
+//   no_ref.Run();  // Prints "1"
+//   has_ref.Run();  // Prints "1"
+//
+//   n = 2;
+//   no_ref.Run();  // Prints "1"
+//   has_ref.Run();  // Prints "2"
+//
+// Note that because ConstRef() takes a reference on |n|, |n| must outlive all
+// its bound callbacks.
+//
+//
+// EXAMPLE OF IgnoreResult():
+//
+//   int DoSomething(int arg) { cout << arg << endl; }
+//
+//   // Assign to a Callback with a void return type.
+//   Callback<void(int)> cb = Bind(IgnoreResult(&DoSomething));
+//   cb->Run(1);  // Prints "1".
+//
+//   // Prints "1" on |ml|.
+//   ml->PostTask(FROM_HERE, Bind(IgnoreResult(&DoSomething), 1);
+//
+//
+// EXAMPLE OF Passed():
+//
+//   void TakesOwnership(scoped_ptr<Foo> arg) { }
+//   scoped_ptr<Foo> CreateFoo() { return scoped_ptr<Foo>(new Foo()); }
+//
+//   scoped_ptr<Foo> f(new Foo());
+//
+//   // |cb| is given ownership of Foo(). |f| is now NULL.
+//   // You can use f.Pass() in place of &f, but it's more verbose.
+//   Closure cb = Bind(&TakesOwnership, Passed(&f));
+//
+//   // Run was never called so |cb| still owns Foo() and deletes
+//   // it on Reset().
+//   cb.Reset();
+//
+//   // |cb| is given a new Foo created by CreateFoo().
+//   cb = Bind(&TakesOwnership, Passed(CreateFoo()));
+//
+//   // |arg| in TakesOwnership() is given ownership of Foo(). |cb|
+//   // no longer owns Foo() and, if reset, would not delete Foo().
+//   cb.Run();  // Foo() is now transferred to |arg| and deleted.
+//   cb.Run();  // This CHECK()s since Foo() already been used once.
+//
+// Passed() is particularly useful with PostTask() when you are transferring
+// ownership of an argument into a task, but don't necessarily know if the
+// task will always be executed. This can happen if the task is cancellable
+// or if it is posted to a MessageLoopProxy.
+//
+//
+// SIMPLE FUNCTIONS AND UTILITIES.
+//
+//   DoNothing() - Useful for creating a Closure that does nothing when called.
+//   DeletePointer<T>() - Useful for creating a Closure that will delete a
+//                        pointer when invoked. Only use this when necessary.
+//                        In most cases MessageLoop::DeleteSoon() is a better
+//                        fit.

+// http://stackoverflow.com/questions/1966362/sfinae-to-check-for-inherited-member-functions
+//
+// The last link in particular show the method used below.
+//
+// For SFINAE to work with inherited methods, we need to pull some extra tricks
+// with multiple inheritance.  In the more standard formulation, the overloads
+// of Check would be:
+//
+//   template <typename C>
+//   Yes NotTheCheckWeWant(Helper<&C::TargetFunc>*);
+//
+//   template <typename C>
+//   No NotTheCheckWeWant(...);
+//
+//   static const bool value = sizeof(NotTheCheckWeWant<T>(0)) == sizeof(Yes);
+//
+// The problem here is that template resolution will not match
+// C::TargetFunc if TargetFunc does not exist directly in C.  That is, if
+// TargetFunc in inherited from an ancestor, &C::TargetFunc will not match,
+// |value| will be false.  This formulation only checks for whether or
+// not TargetFunc exist directly in the class being introspected.
+//
+// To get around this, we play a dirty trick with multiple inheritance.
+// First, We create a class BaseMixin that declares each function that we
+// want to probe for.  Then we create a class Base that inherits from both T
+// (the class we wish to probe) and BaseMixin.  Note that the function
+// signature in BaseMixin does not need to match the signature of the function
+// we are probing for; thus it's easiest to just use void(void).
+//
+// Now, if TargetFunc exists somewhere in T, then &Base::TargetFunc has an
+// ambiguous resolution between BaseMixin and T.  This lets us write the
+// following:
+//
+//   template <typename C>
+//   No GoodCheck(Helper<&C::TargetFunc>*);
+//
+//   template <typename C>
+//   Yes GoodCheck(...);
+//
+//   static const bool value = sizeof(GoodCheck<Base>(0)) == sizeof(Yes);
+//
+// Notice here that the variadic version of GoodCheck() returns Yes here
+// instead of No like the previous one. Also notice that we calculate |value|
+// by specializing GoodCheck() on Base instead of T.
+//
+// We've reversed the roles of the variadic, and Helper overloads.
+// GoodCheck(Helper<&C::TargetFunc>*), when C = Base, fails to be a valid
+// substitution if T::TargetFunc exists. Thus GoodCheck<Base>(0) will resolve
+// to the variadic version if T has TargetFunc.  If T::TargetFunc does not
+// exist, then &C::TargetFunc is not ambiguous, and the overload resolution
+// will prefer GoodCheck(Helper<&C::TargetFunc>*).
+//
+// This method of SFINAE will correctly probe for inherited names, but it cannot
+// typecheck those names.  It's still a good enough sanity check though.
+//
+// Works on gcc-4.2, gcc-4.4, and Visual Studio 2008.
+//
+// TODO(ajwong): Move to ref_counted.h or template_util.h when we've vetted
+// this works well.
+//
+// TODO(ajwong): Make this check for Release() as well.

+// -----------------------------------------------------------------------------
+// Introduction
+// -----------------------------------------------------------------------------
+//
+// The templated Callback class is a generalized function object. Together
+// with the Bind() function in bind.h, they provide a type-safe method for
+// performing partial application of functions.
+//
+// Partial application (or "currying") is the process of binding a subset of
+// a function's arguments to produce another function that takes fewer
+// arguments. This can be used to pass around a unit of delayed execution,
+// much like lexical closures are used in other languages. For example, it
+// is used in Chromium code to schedule tasks on different MessageLoops.
+//
+// A callback with no unbound input parameters (base::Callback<void(void)>)
+// is called a base::Closure. Note that this is NOT the same as what other
+// languages refer to as a closure -- it does not retain a reference to its
+// enclosing environment.
+//
+// MEMORY MANAGEMENT AND PASSING
+//
+// The Callback objects themselves should be passed by const-reference, and
+// stored by copy. They internally store their state via a refcounted class
+// and thus do not need to be deleted.
+//
+// The reason to pass via a const-reference is to avoid unnecessary
+// AddRef/Release pairs to the internal state.
+//
+//
+// -----------------------------------------------------------------------------
+// Quick reference for basic stuff
+// -----------------------------------------------------------------------------
+//
+// BINDING A BARE FUNCTION
+//
+//   int Return5() { return 5; }
+//   base::Callback<int(void)> func_cb = base::Bind(&Return5);
+//   LOG(INFO) << func_cb.Run();  // Prints 5.
+//
+// BINDING A CLASS METHOD
+//
+//   The first argument to bind is the member function to call, the second is
+//   the object on which to call it.
+//
+//   class Ref : public base::RefCountedThreadSafe<Ref> {
+//    public:
+//     int Foo() { return 3; }
+//     void PrintBye() { LOG(INFO) << "bye."; }
+//   };
+//   scoped_refptr<Ref> ref = new Ref();
+//   base::Callback<void(void)> ref_cb = base::Bind(&Ref::Foo, ref);
+//   LOG(INFO) << ref_cb.Run();  // Prints out 3.
+//
+//   By default the object must support RefCounted or you will get a compiler
+//   error. If you're passing between threads, be sure it's
+//   RefCountedThreadSafe! See "Advanced binding of member functions" below if
+//   you don't want to use reference counting.
+//
+// RUNNING A CALLBACK
+//
+//   Callbacks can be run with their "Run" method, which has the same
+//   signature as the template argument to the callback.
+//
+//   void DoSomething(const base::Callback<void(int, std::string)>& callback) {
+//     callback.Run(5, "hello");
+//   }
+//
+//   Callbacks can be run more than once (they don't get deleted or marked when
+//   run). However, this precludes using base::Passed (see below).
+//
+//   void DoSomething(const base::Callback<double(double)>& callback) {
+//     double myresult = callback.Run(3.14159);
+//     myresult += callback.Run(2.71828);
+//   }
+//
+// PASSING UNBOUND INPUT PARAMETERS
+//
+//   Unbound parameters are specified at the time a callback is Run(). They are
+//   specified in the Callback template type:
+//
+//   void MyFunc(int i, const std::string& str) {}
+//   base::Callback<void(int, const std::string&)> cb = base::Bind(&MyFunc);
+//   cb.Run(23, "hello, world");
+//
+// PASSING BOUND INPUT PARAMETERS
+//
+//   Bound parameters are specified when you create thee callback as arguments
+//   to Bind(). They will be passed to the function and the Run()ner of the
+//   callback doesn't see those values or even know that the function it's
+//   calling.
+//
+//   void MyFunc(int i, const std::string& str) {}
+//   base::Callback<void(void)> cb = base::Bind(&MyFunc, 23, "hello world");
+//   cb.Run();
+//
+//   A callback with no unbound input parameters (base::Callback<void(void)>)
+//   is called a base::Closure. So we could have also written:
+//
+//   base::Closure cb = base::Bind(&MyFunc, 23, "hello world");
+//
+//   When calling member functions, bound parameters just go after the object
+//   pointer.
+//
+//   base::Closure cb = base::Bind(&MyClass::MyFunc, this, 23, "hello world");
+//
+// PARTIAL BINDING OF PARAMETERS
+//
+//   You can specify some parameters when you create the callback, and specify
+//   the rest when you execute the callback.
+//
+//   void MyFunc(int i, const std::string& str) {}
+//   base::Callback<void(const std::string&)> cb = base::Bind(&MyFunc, 23);
+//   cb.Run("hello world");
+//
+//   When calling a function bound parameters are first, followed by unbound
+//   parameters.
+//
+//
+// -----------------------------------------------------------------------------
+// Quick reference for advanced binding
+// -----------------------------------------------------------------------------
+//
+// BINDING A CLASS METHOD WITH WEAK POINTERS
+//
+//   base::Bind(&MyClass::Foo, GetWeakPtr());
+//
+//   The callback will not be run if the object has already been destroyed.
+//   DANGER: weak pointers are not threadsafe, so don't use this
+//   when passing between threads!
+//
+// BINDING A CLASS METHOD WITH MANUAL LIFETIME MANAGEMENT
+//
+//   base::Bind(&MyClass::Foo, base::Unretained(this));
+//
+//   This disables all lifetime management on the object. You're responsible
+//   for making sure the object is alive at the time of the call. You break it,
+//   you own it!
+//
+// BINDING A CLASS METHOD AND HAVING THE CALLBACK OWN THE CLASS
+//
+//   MyClass* myclass = new MyClass;
+//   base::Bind(&MyClass::Foo, base::Owned(myclass));
+//
+//   The object will be deleted when the callback is destroyed, even if it's
+//   not run (like if you post a task during shutdown). Potentially useful for
+//   "fire and forget" cases.
+//
+// IGNORING RETURN VALUES
+//
+//   Sometimes you want to call a function that returns a value in a callback
+//   that doesn't expect a return value.
+//
+//   int DoSomething(int arg) { cout << arg << endl; }
+//   base::Callback<void<int>) cb =
+//       base::Bind(base::IgnoreResult(&DoSomething));
+//
+//
+// -----------------------------------------------------------------------------
+// Quick reference for binding parameters to Bind()
+// -----------------------------------------------------------------------------
+//
+// Bound parameters are specified as arguments to Bind() and are passed to the
+// function. A callback with no parameters or no unbound parameters is called a
+// Closure (base::Callback<void(void)> and base::Closure are the same thing).
+//
+// PASSING PARAMETERS OWNED BY THE CALLBACK
+//
+//   void Foo(int* arg) { cout << *arg << endl; }
+//   int* pn = new int(1);
+//   base::Closure foo_callback = base::Bind(&foo, base::Owned(pn));
+//
+//   The parameter will be deleted when the callback is destroyed, even if it's
+//   not run (like if you post a task during shutdown).
+//
+// PASSING PARAMETERS AS A scoped_ptr
+//
+//   void TakesOwnership(scoped_ptr<Foo> arg) {}
+//   scoped_ptr<Foo> f(new Foo);
+//   // f becomes null during the following call.
+//   base::Closure cb = base::Bind(&TakesOwnership, base::Passed(&f));
+//
+//   Ownership of the parameter will be with the callback until the it is run,
+//   when ownership is passed to the callback function. This means the callback
+//   can only be run once. If the callback is never run, it will delete the
+//   object when it's destroyed.
+//
+// PASSING PARAMETERS AS A scoped_refptr
+//
+//   void TakesOneRef(scoped_refptr<Foo> arg) {}
+//   scoped_refptr<Foo> f(new Foo)
+//   base::Closure cb = base::Bind(&TakesOneRef, f);
+//
+//   This should "just work." The closure will take a reference as long as it
+//   is alive, and another reference will be taken for the called function.
+//
+// PASSING PARAMETERS BY REFERENCE
+//
+//   Const references are *copied* unless ConstRef is used. Example:
+//
+//   void foo(const int& arg) { printf("%d %p\n", arg, &arg); }
+//   int n = 1;
+//   base::Closure has_copy = base::Bind(&foo, n);
+//   base::Closure has_ref = base::Bind(&foo, base::ConstRef(n));
+//   n = 2;
+//   foo(n);                        // Prints "2 0xaaaaaaaaaaaa"
+//   has_copy.Run();                // Prints "1 0xbbbbbbbbbbbb"
+//   has_ref.Run();                 // Prints "2 0xaaaaaaaaaaaa"
+//
+//   Normally parameters are copied in the closure. DANGER: ConstRef stores a
+//   const reference instead, referencing the original parameter. This means
+//   that you must ensure the object outlives the callback!
+//
+//
+// -----------------------------------------------------------------------------
+// Implementation notes
+// -----------------------------------------------------------------------------
+//
+// WHERE IS THIS DESIGN FROM:
+//
+// The design Callback and Bind is heavily influenced by C++'s
+// tr1::function/tr1::bind, and by the "Google Callback" system used inside
+// Google.
+//
+//
+// HOW THE IMPLEMENTATION WORKS:
+//
+// There are three main components to the system:
+//   1) The Callback classes.
+//   2) The Bind() functions.
+//   3) The arguments wrappers (e.g., Unretained() and ConstRef()).
+//
+// The Callback classes represent a generic function pointer. Internally,
+// it stores a refcounted piece of state that represents the target function
+// and all its bound parameters.  Each Callback specialization has a templated
+// constructor that takes an BindState<>*.  In the context of the constructor,
+// the static type of this BindState<> pointer uniquely identifies the
+// function it is representing, all its bound parameters, and a Run() method
+// that is capable of invoking the target.
+//
+// Callback's constructor takes the BindState<>* that has the full static type
+// and erases the target function type as well as the types of the bound
+// parameters.  It does this by storing a pointer to the specific Run()
+// function, and upcasting the state of BindState<>* to a
+// BindStateBase*. This is safe as long as this BindStateBase pointer
+// is only used with the stored Run() pointer.
+//
+// To BindState<> objects are created inside the Bind() functions.
+// These functions, along with a set of internal templates, are responsible for
+//
+//  - Unwrapping the function signature into return type, and parameters
+//  - Determining the number of parameters that are bound
+//  - Creating the BindState storing the bound parameters
+//  - Performing compile-time asserts to avoid error-prone behavior
+//  - Returning an Callback<> with an arity matching the number of unbound
+//    parameters and that knows the correct refcounting semantics for the
+//    target object if we are binding a method.
+//
+// The Bind functions do the above using type-inference, and template
+// specializations.
+//
+// By default Bind() will store copies of all bound parameters, and attempt
+// to refcount a target object if the function being bound is a class method.
+// These copies are created even if the function takes parameters as const
+// references. (Binding to non-const references is forbidden, see bind.h.)
+//
+// To change this behavior, we introduce a set of argument wrappers
+// (e.g., Unretained(), and ConstRef()).  These are simple container templates
+// that are passed by value, and wrap a pointer to argument.  See the
+// file-level comment in base/bind_helpers.h for more info.
+//
+// These types are passed to the Unwrap() functions, and the MaybeRefcount()
+// functions respectively to modify the behavior of Bind().  The Unwrap()
+// and MaybeRefcount() functions change behavior by doing partial
+// specialization based on whether or not a parameter is a wrapper type.
+//
+// ConstRef() is similar to tr1::cref.  Unretained() is specific to Chromium.
+//
+//
+// WHY NOT TR1 FUNCTION/BIND?
+//
+// Direct use of tr1::function and tr1::bind was considered, but ultimately
+// rejected because of the number of copy constructors invocations involved
+// in the binding of arguments during construction, and the forwarding of
+// arguments during invocation.  These copies will no longer be an issue in
+// C++0x because C++0x will support rvalue reference allowing for the compiler
+// to avoid these copies.  However, waiting for C++0x is not an option.
+//
+// Measured with valgrind on gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5), the
+// tr1::bind call itself will invoke a non-trivial copy constructor three times
+// for each bound parameter.  Also, each when passing a tr1::function, each
+// bound argument will be copied again.
+//
+// In addition to the copies taken at binding and invocation, copying a
+// tr1::function causes a copy to be made of all the bound parameters and
+// state.
+//
+// Furthermore, in Chromium, it is desirable for the Callback to take a
+// reference on a target object when representing a class method call.  This
+// is not supported by tr1.
+//
+// Lastly, tr1::function and tr1::bind has a more general and flexible API.
+// This includes things like argument reordering by use of
+// tr1::bind::placeholder, support for non-const reference parameters, and some
+// limited amount of subtyping of the tr1::function object (e.g.,
+// tr1::function<int(int)> is convertible to tr1::function<void(int)>).
+//
+// These are not features that are required in Chromium. Some of them, such as
+// allowing for reference parameters, and subtyping of functions, may actually
+// become a source of errors. Removing support for these features actually
+// allows for a simpler implementation, and a terser Currying API.
+//
+//
+// WHY NOT GOOGLE CALLBACKS?
+//
+// The Google callback system also does not support refcounting.  Furthermore,
+// its implementation has a number of strange edge cases with respect to type
+// conversion of its arguments.  In particular, the argument's constness must
+// at times match exactly the function signature, or the type-inference might
+// break.  Given the above, writing a custom solution was easier.
+//
+//
+// MISSING FUNCTIONALITY
+//  - Invoking the return of Bind.  Bind(&foo).Run() does not work;
+//  - Binding arrays to functions that take a non-const pointer.
+//    Example:
+//      void Foo(const char* ptr);
+//      void Bar(char* ptr);
+//      Bind(&Foo, "test");
+//      Bind(&Bar, "test");  // This fails because ptr is not const.

+// Macro with the boilerplate that makes a type move-only in C++03.
+//
+// USAGE
+//
+// This macro should be used instead of DISALLOW_COPY_AND_ASSIGN to create
+// a "move-only" type.  Unlike DISALLOW_COPY_AND_ASSIGN, this macro should be
+// the first line in a class declaration.
+//
+// A class using this macro must call .Pass() (or somehow be an r-value already)
+// before it can be:
+//
+//   * Passed as a function argument
+//   * Used as the right-hand side of an assignment
+//   * Returned from a function
+//
+// Each class will still need to define their own "move constructor" and "move
+// operator=" to make this useful.  Here's an example of the macro, the move
+// constructor, and the move operator= from the scoped_ptr class:
+//
+//  template <typename T>
+//  class scoped_ptr {
+//     MOVE_ONLY_TYPE_FOR_CPP_03(scoped_ptr, RValue)
+//   public:
+//    scoped_ptr(RValue& other) : ptr_(other.release()) { }
+//    scoped_ptr& operator=(RValue& other) {
+//      swap(other);
+//      return *this;
+//    }
+//  };
+//
+// Note that the constructor must NOT be marked explicit.
+//
+// For consistency, the second parameter to the macro should always be RValue
+// unless you have a strong reason to do otherwise.  It is only exposed as a
+// macro parameter so that the move constructor and move operator= don't look
+// like they're using a phantom type.
+//
+//
+// HOW THIS WORKS
+//
+// For a thorough explanation of this technique, see:
+//
+//   http://en.wikibooks.org/wiki/More_C%2B%2B_Idioms/Move_Constructor
+//
+// The summary is that we take advantage of 2 properties:
+//
+//   1) non-const references will not bind to r-values.
+//   2) C++ can apply one user-defined conversion when initializing a
+//      variable.
+//
+// The first lets us disable the copy constructor and assignment operator
+// by declaring private version of them with a non-const reference parameter.
+//
+// For l-values, direct initialization still fails like in
+// DISALLOW_COPY_AND_ASSIGN because the copy constructor and assignment
+// operators are private.
+//
+// For r-values, the situation is different. The copy constructor and
+// assignment operator are not viable due to (1), so we are trying to call
+// a non-existent constructor and non-existing operator= rather than a private
+// one.  Since we have not committed an error quite yet, we can provide an
+// alternate conversion sequence and a constructor.  We add
+//
+//   * a private struct named "RValue"
+//   * a user-defined conversion "operator RValue()"
+//   * a "move constructor" and "move operator=" that take the RValue& as
+//     their sole parameter.
+//
+// Only r-values will trigger this sequence and execute our "move constructor"
+// or "move operator=."  L-values will match the private copy constructor and
+// operator= first giving a "private in this context" error.  This combination
+// gives us a move-only type.
+//
+// For signaling a destructive transfer of data from an l-value, we provide a
+// method named Pass() which creates an r-value for the current instance
+// triggering the move constructor or move operator=.
+//
+// Other ways to get r-values is to use the result of an expression like a
+// function call.
+//
+// Here's an example with comments explaining what gets triggered where:
+//
+//    class Foo {
+//      MOVE_ONLY_TYPE_FOR_CPP_03(Foo, RValue);
+//
+//     public:
+//       ... API ...
+//       Foo(RValue other);           // Move constructor.
+//       Foo& operator=(RValue rhs);  // Move operator=
+//    };
+//
+//    Foo MakeFoo();  // Function that returns a Foo.
+//
+//    Foo f;
+//    Foo f_copy(f);  // ERROR: Foo(Foo&) is private in this context.
+//    Foo f_assign;
+//    f_assign = f;   // ERROR: operator=(Foo&) is private in this context.
+//
+//
+//    Foo f(MakeFoo());      // R-value so alternate conversion executed.
+//    Foo f_copy(f.Pass());  // R-value so alternate conversion executed.
+//    f = f_copy.Pass();     // R-value so alternate conversion executed.
+//
+//
+// IMPLEMENTATION SUBTLETIES WITH RValue
+//
+// The RValue struct is just a container for a pointer back to the original
+// object. It should only ever be created as a temporary, and no external
+// class should ever declare it or use it in a parameter.
+//
+// It is tempting to want to use the RValue type in function parameters, but
+// excluding the limited usage here for the move constructor and move
+// operator=, doing so would mean that the function could take both r-values
+// and l-values equially which is unexpected.  See COMPARED To Boost.Move for
+// more details.
+//
+// An alternate, and incorrect, implementation of the RValue class used by
+// Boost.Move makes RValue a fieldless child of the move-only type. RValue&
+// is then used in place of RValue in the various operators.  The RValue& is
+// "created" by doing *reinterpret_cast<RValue*>(this).  This has the appeal
+// of never creating a temporary RValue struct even with optimizations
+// disabled.  Also, by virtue of inheritance you can treat the RValue
+// reference as if it were the move-only type itself.  Unfortunately,
+// using the result of this reinterpret_cast<> is actually undefined behavior
+// due to C++98 5.2.10.7. In certain compilers (e.g., NaCl) the optimizer
+// will generate non-working code.
+//
+// In optimized builds, both implementations generate the same assembly so we
+// choose the one that adheres to the standard.
+//
+//
+// WHY HAVE typedef void MoveOnlyTypeForCPP03
+//
+// Callback<>/Bind() needs to understand movable-but-not-copyable semantics
+// to call .Pass() appropriately when it is expected to transfer the value.
+// The cryptic typedef MoveOnlyTypeForCPP03 is added to make this check
+// easy and automatic in helper templates for Callback<>/Bind().
+// See IsMoveOnlyType template and its usage in base/callback_internal.h
+// for more details.
+//
+//
+// COMPARED TO C++11
+//
+// In C++11, you would implement this functionality using an r-value reference
+// and our .Pass() method would be replaced with a call to std::move().
+//
+// This emulation also has a deficiency where it uses up the single
+// user-defined conversion allowed by C++ during initialization.  This can
+// cause problems in some API edge cases.  For instance, in scoped_ptr, it is
+// impossible to make a function "void Foo(scoped_ptr<Parent> p)" accept a
+// value of type scoped_ptr<Child> even if you add a constructor to
+// scoped_ptr<> that would make it look like it should work.  C++11 does not
+// have this deficiency.
+//
+//
+// COMPARED TO Boost.Move
+//
+// Our implementation similar to Boost.Move, but we keep the RValue struct
+// private to the move-only type, and we don't use the reinterpret_cast<> hack.
+//
+// In Boost.Move, RValue is the boost::rv<> template.  This type can be used
+// when writing APIs like:
+//
+//   void MyFunc(boost::rv<Foo>& f)
+//
+// that can take advantage of rv<> to avoid extra copies of a type.  However you
+// would still be able to call this version of MyFunc with an l-value:
+//
+//   Foo f;
+//   MyFunc(f);  // Uh oh, we probably just destroyed |f| w/o calling Pass().
+//
+// unless someone is very careful to also declare a parallel override like:
+//
+//   void MyFunc(const Foo& f)
+//
+// that would catch the l-values first.  This was declared unsafe in C++11 and
+// a C++11 compiler will explicitly fail MyFunc(f).  Unfortunately, we cannot
+// ensure this in C++03.
+//

+// Scopers help you manage ownership of a pointer, helping you easily manage a
+// pointer within a scope, and automatically destroying the pointer at the end
+// of a scope.  There are two main classes you will use, which correspond to the
+// operators new/delete and new[]/delete[].
+//
+// Example usage (scoped_ptr<T>):
+//   {
+//     scoped_ptr<Foo> foo(new Foo("wee"));
+//   }  // foo goes out of scope, releasing the pointer with it.
+//
+//   {
+//     scoped_ptr<Foo> foo;          // No pointer managed.
+//     foo.reset(new Foo("wee"));    // Now a pointer is managed.
+//     foo.reset(new Foo("wee2"));   // Foo("wee") was destroyed.
+//     foo.reset(new Foo("wee3"));   // Foo("wee2") was destroyed.
+//     foo->Method();                // Foo::Method() called.
+//     foo.get()->Method();          // Foo::Method() called.
+//     SomeFunc(foo.release());      // SomeFunc takes ownership, foo no longer
+//                                   // manages a pointer.
+//     foo.reset(new Foo("wee4"));   // foo manages a pointer again.
+//     foo.reset();                  // Foo("wee4") destroyed, foo no longer
+//                                   // manages a pointer.
+//   }  // foo wasn't managing a pointer, so nothing was destroyed.
+//
+// Example usage (scoped_ptr<T[]>):
+//   {
+//     scoped_ptr<Foo[]> foo(new Foo[100]);
+//     foo.get()->Method();  // Foo::Method on the 0th element.
+//     foo[10].Method();     // Foo::Method on the 10th element.
+//   }
+//
+// These scopers also implement part of the functionality of C++11 unique_ptr
+// in that they are "movable but not copyable."  You can use the scopers in
+// the parameter and return types of functions to signify ownership transfer
+// in to and out of a function.  When calling a function that has a scoper
+// as the argument type, it must be called with the result of an analogous
+// scoper's Pass() function or another function that generates a temporary;
+// passing by copy will NOT work.  Here is an example using scoped_ptr:
+//
+//   void TakesOwnership(scoped_ptr<Foo> arg) {
+//     // Do something with arg
+//   }
+//   scoped_ptr<Foo> CreateFoo() {
+//     // No need for calling Pass() because we are constructing a temporary
+//     // for the return value.
+//     return scoped_ptr<Foo>(new Foo("new"));
+//   }
+//   scoped_ptr<Foo> PassThru(scoped_ptr<Foo> arg) {
+//     return arg.Pass();
+//   }
+//
+//   {
+//     scoped_ptr<Foo> ptr(new Foo("yay"));  // ptr manages Foo("yay").
+//     TakesOwnership(ptr.Pass());           // ptr no longer owns Foo("yay").
+//     scoped_ptr<Foo> ptr2 = CreateFoo();   // ptr2 owns the return Foo.
+//     scoped_ptr<Foo> ptr3 =                // ptr3 now owns what was in ptr2.
+//         PassThru(ptr2.Pass());            // ptr2 is correspondingly NULL.
+//   }
+//
+// Notice that if you do not call Pass() when returning from PassThru(), or
+// when invoking TakesOwnership(), the code will not compile because scopers
+// are not copyable; they only implement move semantics which require calling
+// the Pass() function to signify a destructive transfer of state. CreateFoo()
+// is different though because we are constructing a temporary on the return
+// line and thus can avoid needing to call Pass().
+//
+// Pass() properly handles upcast in initialization, i.e. you can use a
+// scoped_ptr<Child> to initialize a scoped_ptr<Parent>:
+//
+//   scoped_ptr<Foo> foo(new Foo());
+//   scoped_ptr<FooParent> parent(foo.Pass());
+//
+// PassAs<>() should be used to upcast return value in return statement:
+//
+//   scoped_ptr<Foo> CreateFoo() {
+//     scoped_ptr<FooChild> result(new FooChild());
+//     return result.PassAs<Foo>();
+//   }
+//
+// Note that PassAs<>() is implemented only for scoped_ptr<T>, but not for
+// scoped_ptr<T[]>. This is because casting array pointers may not be safe.

-//
-//   {
-//     scoped_refptr<MyFoo> a = MakeRefCounted<MyFoo>();
-//     scoped_refptr<MyFoo> b;
-//
-//     b = a;
-//     // now, |a| and |b| each own a reference to the same MyFoo object.

-//
-// Also see Chromium's ownership and calling conventions:
-// https://chromium.googlesource.com/chromium/src/+/lkgr/styleguide/c++/c++.md#object-ownership-and-calling-conventions
-// Specifically:
-//   If the function (at least sometimes) takes a ref on a refcounted object,
-//   declare the param as scoped_refptr<T>. The caller can decide whether it
-//   wishes to transfer ownership (by calling std::move(t) when passing t) or
-//   retain its ref (by simply passing t directly).
-//   In other words, use scoped_refptr like you would a std::unique_ptr except
-//   in the odd case where it's required to hold on to a ref while handing one
-//   to another component (if a component merely needs to use t on the stack
-//   without keeping a ref: pass t as a raw T*).

+// WHAT:
+// A version of std::basic_string that provides 2-byte characters even when
+// wchar_t is not implemented as a 2-byte type. You can access this class as
+// string16. We also define char16, which string16 is based upon.
+//
+// WHY:
+// On Windows, wchar_t is 2 bytes, and it can conveniently handle UTF-16/UCS-2
+// data. Plenty of existing code operates on strings encoded as UTF-16.
+//
+// On many other platforms, sizeof(wchar_t) is 4 bytes by default. We can make
+// it 2 bytes by using the GCC flag -fshort-wchar. But then std::wstring fails
+// at run time, because it calls some functions (like wcslen) that come from
+// the system's native C library -- which was built with a 4-byte wchar_t!
+// It's wasteful to use 4-byte wchar_t strings to carry UTF-16 data, and it's
+// entirely improper on those systems where the encoding of wchar_t is defined
+// as UTF-32.
+//
+// Here, we define string16, which is similar to std::wstring but replaces all
+// libc functions with custom, 2-byte-char compatible routines. It is capable
+// of carrying UTF-16-encoded data.

+// as assignment or destruction is performed on a string, causing its existing
+// data member to be invalidated, it must not be freed if this static data
+// member is being used.  Otherwise, it counts as an attempt to free static
+// (and not allocated) data, which is a memory error.
+//
+// Generally, due to C++ template magic, _S_empty_rep_storage will be marked
+// as a coalesced symbol, meaning that the linker will combine multiple
+// instances into a single one when generating output.
+//
+// If a string class is used by multiple shared libraries, a problem occurs.
+// Each library will get its own copy of _S_empty_rep_storage.  When strings
+// are passed across a library boundary for alteration or destruction, memory
+// errors will result.  GNU libstdc++ contains a configuration option,
+// --enable-fully-dynamic-string (_GLIBCXX_FULLY_DYNAMIC_STRING), which
+// disables the static data member optimization, but it's a good optimization
+// and non-STL code is generally at the mercy of the system's STL
+// configuration.  Fully-dynamic strings are not the default for GNU libstdc++
+// libstdc++ itself or for the libstdc++ installations on the systems we care
+// about, such as Mac OS X and relevant flavors of Linux.
+//
+// See also http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24196 .
+//
+// To avoid problems, string classes need to be explicitly instantiated only
+// once, in exactly one library.  All other string users see it via an "extern"
+// declaration.  This is precisely how GNU libstdc++ handles
+// std::basic_string<char> (string) and std::basic_string<wchar_t> (wstring).
+//
+// This also works around a Mac OS X linker bug in ld64-85.2.1 (Xcode 3.1.2),
+// in which the linker does not fully coalesce symbols when dead code
+// stripping is enabled.  This bug causes the memory errors described above
+// to occur even when a std::basic_string<> does not cross shared library

-// Implement this structure to handle events related to cef_frame_t life span.
-// The order of callbacks is:
-//
-// (1) During initial cef_browser_host_t creation and navigation of the main
-// frame: - cef_frame_handler_t::OnFrameCreated => The initial main frame object
-// has been
-//   created. Any commands will be queued until the frame is attached.
-// - cef_frame_handler_t::OnMainFrameChanged => The initial main frame object
-// has
-//   been assigned to the browser.
-// - cef_life_span_handler_t::OnAfterCreated => The browser is now valid and can
-// be
-//   used.
-// - cef_frame_handler_t::OnFrameAttached => The initial main frame object is
-// now
-//   connected to its peer in the renderer process. Commands can be routed.
-//
-// (2) During further cef_browser_host_t navigation/loading of the main frame
-// and/or sub-frames: - cef_frame_handler_t::OnFrameCreated => A new main frame
-// or sub-frame object has
-//   been created. Any commands will be queued until the frame is attached.
-// - cef_frame_handler_t::OnFrameAttached => A new main frame or sub-frame
-// object is
-//   now connected to its peer in the renderer process. Commands can be routed.
-// - cef_frame_handler_t::OnFrameDetached => An existing main frame or sub-frame
-//   object has lost its connection to the renderer process. If multiple objects
-//   are detached at the same time then notifications will be sent for any
-//   sub-frame objects before the main frame object. Commands can no longer be
-//   routed and will be discarded.
-// - cef_frame_handler_t::OnMainFrameChanged => A new main frame object has been
-//   assigned to the browser. This will only occur with cross-origin navigation
-//   or re-navigation after renderer process termination (due to crashes, etc).
-//
-// (3) During final cef_browser_host_t destruction of the main frame: -
-// cef_frame_handler_t::OnFrameDetached => Any sub-frame objects have lost their
-//   connection to the renderer process. Commands can no longer be routed and
-//   will be discarded.
-// - cef_life_span_handler_t::OnBeforeClose => The browser has been destroyed. -
-// cef_frame_handler_t::OnFrameDetached => The main frame object have lost its
-//   connection to the renderer process. Notifications will be sent for any
-//   sub-frame objects before the main frame object. Commands can no longer be
-//   routed and will be discarded.
-// - cef_frame_handler_t::OnMainFrameChanged => The final main frame object has
-// been
-//   removed from the browser.
-//
-// Cross-origin navigation and/or loading receives special handling.
-//
-// When the main frame navigates to a different origin the OnMainFrameChanged
-// callback (2) will be executed with the old and new main frame objects.
-//
-// When a new sub-frame is loaded in, or an existing sub-frame is navigated to,
-// a different origin from the parent frame, a temporary sub-frame object will
-// first be created in the parent's renderer process. That temporary sub-frame
-// will then be discarded after the real cross-origin sub-frame is created in
-// the new/target renderer process. The client will receive cross-origin
-// navigation callbacks (2) for the transition from the temporary sub-frame to
-// the real sub-frame. The temporary sub-frame will not recieve or execute
-// commands during this transitional period (any sent commands will be
-// discarded).
-//
-// When a new popup browser is created in a different origin from the parent
-// browser, a temporary main frame object for the popup will first be created in
-// the parent's renderer process. That temporary main frame will then be
-// discarded after the real cross-origin main frame is created in the new/target
-// renderer process. The client will recieve creation and initial navigation
-// callbacks (1) for the temporary main frame, followed by cross-origin
-// navigation callbacks (2) for the transition from the temporary main frame to
-// the real main frame. The temporary main frame may receive and execute
-// commands during this transitional period (any sent commands may be executed,
-// but the behavior is potentially undesirable since they execute in the parent
-// browser's renderer process and not the new/target renderer process).
-//
-// Callbacks will not be executed for placeholders that may be created during
-// pre-commit navigation for sub-frames that do not yet exist in the renderer
-// process. Placeholders will have cef_frame_t::get_identifier() == -4.
