Move network thread invokes for initialization for media channels, out.

Remove Init_w and Deinit(), both of which were wrappers around Invoke()
calls from the worker thread to the network thread.

Instead, replace them with Init_n() and Deinit_n() that are currently*
required to be called by external code in order to associate/disassociate
the channels with the transport.

This CL mostly moves things around in order to prepare for upcoming
changes, but it does change channel destruction in the following way:
- When destroying channels, we don't block the worker thread anymore
  while uninitialization happens on the network thread. Previously
  both signal and worker threads were blocked during the
  uninitialization in the ChannelManager.

* In an upcoming CL, Init_n() and Deinit_n() will be called internally
  from a different method that's always called on the network thread
  when a channel is associated/disassociated with a transceiver. When
  we're there, we will have removed several invokes that currently are
  a part of constructing/destructing channel objects.
