* Handle an edge in layer lock.
A very edge case
- Available layer: [0, 1, 2], but bitrate is not yet available.
We set it to layer 2 awaiting measurement.
- Measurement for layers 0 and 1 come through.
- Still no key frame for layer 2.
- Finalize layers runs and sees that bitrate is available for 0 and 1.
It finalizes layer 1.
- Layer 1 key frame comes (because we asked key frame of layer 2,
publisher sends key frame for all layers). Locks to layer 1.
- No more events happen to switch to layer 2.
Changes
-------
- Move bit rate measurement to StreamTrackerManager. Allows re-use
in relay.
- Make bit rate availability (from zero -> non-zero) an event
and let it flow through the stream allocation flow so that we
always have an event when bit rate measurement becomes available.
This gets rid of finalization which I was unhappy with it anyway as
it was polling every second.
- Removing REMB stuff from buffer. We do not use it.
It is incorrect anyway. REMB should be ay peer connection level.
* Fix test
* fix test
* Simplify allocate
* Simplify/clean up
* feat: unpublish tracks after publish permissions are revoked.
Uses protocol 7 to indicate client support, otherwise it attempts to
mute the tracks.
Also sends back permissions objects of all participants, and cleaned up
our handling of various permissions attributes.
* fix static check
* Telemetry and webhook improvements.
* avoid blocking on telemetry channel - increase channel size and drop when full
* send ParticipantJoined webhook when fully joined (i.e. on ParticipantActive)
* send TrackPublished & TrackUnpublished webhooks
* increase number of parallel webhook workers to 50
* update protocol
This still does not address root cause of large loss, but at least
does not display crazy thing like packets = 0, but packet rate is 45/s.
Also, RLock in ToString() as there are bits of structure used in
stringification.
* fix keyFrameRequestGeneration not exit after close
* change to bound check
* Refactor stop key frame requester into a function
* Remove redundant key frame requester stop
