PostMessageWithFunctor() added.

This function is used to post messages onto rtc::Threads. The thread
invokes the functor without blocking the calling thread. Messages posted
in this way are executed in the order that they were posted. This is
meant to work as the equivalent of "thread->PostTask()" in Chromium.

Note: AsyncInvoker currently does something similar but it is more
cumbersome to use (somebody has to create it and own it and make sure
not to destroy it while tasks are pending or else they're cancelled). It
also comes with a fundamental flaw: You cannot destroy the AsyncInvoker
from within the functor (this results in a neverending Wait). This makes
the AsyncInvoker not suitable for implementing "destructor traits"
amongst other things.

This CL will allow us to easily add "PostTask()" to rtc::Thread or add
support for DestructorTraits, which is especially useful when you have a
reference counted object that is referenced from multiple threads but
owns resources that has to be destroyed on a particular thread.

Blocking invokes are forbidden in Chromium but WebRTC performs them
frequently. Being able to perform the equivalent of PostTask() is a
good thing.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development

See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
