Rename client status to data, add group data.
...
We now distinguish between status, which is maintained by the server,
and data, which is provided by the client. In addition to client data,
we now support group data.

Add ability to set initial user status.
...
Setting the status after joining (using the "setstatus" action)
may cause multiple "user" messages to be sent to clients. Add
the ability to set the initial status at join time.

We now restrict the allowable codecs in the downstream direction,
which leads to a clean failure instead of a silent track. We also
allow multiple profiles for a single codec.

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.
