We should pass down the value to each Transport even if it doesn't have
Channels, and then each Transport needs to remember it and apply it to each new
TransportChannel that it creates.

Done.

I think we need to store the value and then apply it to each Transport that we
create when we create them.  Such logic probably belongs in BaseSession, not
WebRtcSession.  It would be better if we already had the TransportController
class instead of BaseSession, but BaseSession should work for now.

Done.
