Implement group status.
...
We now inform clients of the status of a group (locked, etc.). Also
cleans up the handling of administrative messages, which solves the
issue of receiving "user" before "joined".

Use sequence parameter sets for h.264 keyframe detection.

RFC 6184 Section 8.5.1 implies that the sender will send a
a sequence parameter set in response to PLI. Since a keyframe is
useless without parameters, use the SPS to detect keyframes.

Label streams, not tracks.
...
We used to label tracks individually, in a view to using the labelling
for simulcast. Since then, the WebRTC community has converged on a
different strategy, where multiple tracks share a single mid and
are labelled with the rid extension.
We now label whole streams, which is simpler, and use the track's
kind (and, in the future, the rid) to disambiguate. This changes the
protocol in two ways:
* in offers, the "labels" dictionary is replaced by a single "label"
field; and
* the syntax of the "request" message has changed.
