Qingsi Wang 502db3df4e Replace MessageHandler by AsyncInvoker in P2PTransportChannel.
The existing asynchronous task execution in P2PTransportChannel is
implemented by posting messages to its network thread (a rtc::Thread)
and consuming these messages as a MessageHandler. The readability of
the implementation can be improved by using AsyncInvoker, which is
exactly designed for this scenario.
