6aa7a9394a More tweaks to layer switching. 
I'm not seeing any non-keyframe spatial sync frames, so simplify
the code by only switching spatial layers on keyframes.

d29f6d6e5d Make video close button more visible. 
Adds a round black semi-transparent background to the white cross icon,
making it visible in any situation.

9093339b62 Rework handling of buffered keyframes. 
Instead of buffering the last keyframe, we merely keep track of its
seqno, and use the main cache for recovering.  We also send the whole
sequence of packets rather than just the keyframe itself.

d96a48f805 Don't rewrite PID for VP9. 
Rewriting is not useful for VP9, and even harmful, as it breaks the
offsets in the scalability structure.

48a9b10ce8 Use spatial scalability when simulcast is not available. 
If the client requested a low-resolution stream and there is none,
switch to SID=0.

4f7be19644 Implement pid and mark rewriting for VP9, fix VP9 sync bits. 
The sync bits were incorrect.  In addition, we need to set the
marker at the new end of the frame when doing spatial decimation.

200c0dd68c Refresh layer info after adjusting in down.Write. 
Otherwise we might act on outdated info, which could cause a spurious
drop.

51c31ab729 Improve error handling for negotiation failures. 
Now that we constrain tracks in offers properly, there is no need
to manually check that the codecs have been matched correctly.

816b7a54df Restrict negotiation of downstream codecs, allow multiple profiles. 
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.

The lower interval made us too sensible too scheduling.

Pion is making incompatible changes, so stick with webrtc 3.0 and
rtp 1.6 for now.

This replaces the OverridePermissions method, and is communicated

We store h.264 in Matroska, since we already have the library.
We currently store the video width and height as 0.

7d29ef5a64 Make disk writer use the codecs package. 
Instead of testing whether a sample is a keyframe, we test at the
packet level, then compare timestamps to identify the keyframe.

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".

9b8d868647 Fix a race between delUpConn and addLocal. 
We could call addLocal after the remote was closed, which
would cause the local connection to remain forever.

3d2089f40f Merge GetRTP and Nack into GetPacket. 
The two function were always called together.  This factors out
the NACKing logic into the track.
