RID parsing for Simulcast support.
Adding RidDescription to StreamParams that will contain the list of rids
for the track.
Adding receive_stream to MediaContentDescription to allow identifying
the stream that originates from the answerer (but is referenced by the
sender). For example, to signal that it will be received in Simulcast.
Bug: webrtc:10073.
