+// The following is substantially similar to the Chromium implementation.
+// If the Chromium implementation diverges the below implementation should be

+// 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.

+// 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

-// 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.

-// Implement this interface to handle events related to CefFrame life span. The
-// order of callbacks is:
-//
-// (1) During initial CefBrowserHost creation and navigation of the main frame:
-// - CefFrameHandler::OnFrameCreated => The initial main frame object has been
-//   created. Any commands will be queued until the frame is attached.
-// - CefFrameHandler::OnMainFrameChanged => The initial main frame object has
-//   been assigned to the browser.
-// - CefLifeSpanHandler::OnAfterCreated => The browser is now valid and can be
-//   used.
-// - CefFrameHandler::OnFrameAttached => The initial main frame object is now
-//   connected to its peer in the renderer process. Commands can be routed.
-//
-// (2) During further CefBrowserHost navigation/loading of the main frame and/or
-// sub-frames:
-// - CefFrameHandler::OnFrameCreated => A new main frame or sub-frame object has
-//   been created. Any commands will be queued until the frame is attached.
-// - CefFrameHandler::OnFrameAttached => A new main frame or sub-frame object is
-//   now connected to its peer in the renderer process. Commands can be routed.
-// - CefFrameHandler::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.
-// - CefFrameHandler::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 CefBrowserHost destruction of the main frame:
-// - CefFrameHandler::OnFrameDetached => Any sub-frame objects have lost their
-//   connection to the renderer process. Commands can no longer be routed and
-//   will be discarded.
-// - CefLifeSpanHandler::OnBeforeClose => The browser has been destroyed.
-// - CefFrameHandler::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.
-// - CefFrameHandler::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 CefFrame::GetIdentifier() == -4.
-//
-// The methods of this class will be called on the UI thread unless otherwise
