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.

// Consider the SDP attribute for simulcast a=simulcast:<configuration>.

// having to serialize the entire SDP while hiding implementation details

// from callers of sdp serialization (webrtcsdp.h).
