cef/include/wrapper/cef_stream_resource_handler.h
Marshall Greenblatt 122397acfc Introduce the use of Chromium types (issue #1336).
Changes to the CEF public API:
- Add base::Bind, base::Callback, base::Lock, base::WeakPtr, scoped_refptr, scoped_ptr and supporting types.
- Add include/wrapper/cef_closure_task.h helpers for converting a base::Closure to a CefTask.
- Change CefRefPtr to extend scoped_refptr.
-- Change CefBase method signatures to match RefCountedThreadSafeBase.
- Change IMPLEMENT_REFCOUNTING to use base::AtomicRefCount*.
-- Remove the CefAtomic* functions.
-- IMPLEMENT_REFCOUNTING now enforces via a compile-time error that the correct class name was passed to the macro.
- Change IMPLEMENT_LOCKING to use base::Lock.
-- Remove the CefCriticalSection class.
-- Deprecate the IMPLEMENT_LOCKING macro.
-- base::Lock will DCHECK() in Debug builds if lock usage is reentrant.
- Move include/internal/cef_tuple.h to include/base/cef_tuple.h.
- Allow an empty |callback| parameter passed to CefBeginTracing.

Changes to the CEF implementation:
- Fix incorrect names passed to the IMPLEMENT_REFCOUNTING macro.
- Fix instances of reentrant locking in the CefXmlObject and CefRequest implementations.
- Remove use of the IMPLEMENT_LOCKING macro.

Changes to cef_unittests:
- Add tests/unittests/chromium_includes.h and always include it first from unit test .cc files to avoid name conflicts with Chromium types.
- Fix wrong header include ordering.
- Remove use of the IMPLEMENT_LOCKING macro.

Changes to cefclient and cefsimple:
- Use base::Bind and cef_closure_task.h instead of NewCefRunnable*.
- Remove use of the IMPEMENT_LOCKING macro.
- Fix incorrect/unnecessary locking.
- Add additional runtime thread checks.
- Windows: Perform actions on the UI thread instead of the main thread when running in multi-threaded-message-loop mode to avoid excessive locking.
