Implement data channel methods in LoopbackMediaTransport.

This enables PeerConnection tests to use LoopbackMediaTransport to test
data-channel-over-media-transport code.

Also changes LoopbackMediaTransport to invoke callbacks asynchronously.
This is more accurate, as these callbacks are triggered by network
events.  The caller should not block while the callback executes.

Since LoopbackMediaTransport is used for testing, it provides a
FlushAsyncInvokes() method which may be used to ensure that callbacks
occur deterministically (eg. before checking that data has been
received).
