Pull a DataChannelTransportInterface out of MediaTransportInterface.

DataChannelTransportInterface takes the OpenChannel, SendData,
CloseChannel, and SetDataSink methods.  MediaTransportInterface inherits
from DataChannelTransportInterface.

DatagramTransportInterface, the newer alternative to
MediaTransportInterface, also inherits from
DataChannelTransportInterface.

This will allow further refactors to enable the use of media-transport
style data channels alongside the datagram transport.
