wu@webrtc.org 3c5d2b43ec Thread::Stop() must be called before any subclass's destructor completes.
Update Thread documentation, fix all subclasses that had a problem.

This is to avoid a data racing between the destructor modifying the vtable, and
Thread::PreRun calling virtual method Run at the same time.

For example:
[ RUN      ] FileMediaEngineTest.TestGetCapabilities
==================
WARNING: ThreadSanitizer: data race on vptr (ctor/dtor vs virtual call) (pid=2967)
