I think communicating the stream concept (which streams exist that have
this track as part of it) is important; if we don't communicate it, it's
impossible to reconstruct the streams on the receiving side.

WRT addStream(), if we add addStream(), I think we should define
addStream() in terms of addTrack(): "AddStream() must have identical
semantics to

  for track in stream.getAllTracks() {
     pc.AddTrack(track)
  }

"
(which also argues that we make the specification simpler if we have
getAllTracks in addition to getAudioTracks and getVideoTracks, because
we don't have to worry if a third type of track is added)
