Paul Wells 1ba2cadccd agent: release JobTerminate handler when job ends before registration (#4908)
* agent: release JobTerminate handler when job ends before registration

JobRequest registered the job's JobTerminate handler after AssignJob
returned, so an ended UpdateJobStatus or worker disconnect handled in
between deregistered nothing and the handler leaked. AssignJob also sent
the assignment before recording the job as running, so an immediate
ended update was dropped.

Record the job before sending the assignment, and after registering the
handler recheck under h.mu that the job is still running and its worker
still registered, deregistering otherwise.

Fixes #4901

* replace utils.CloneProto with proto.CloneOf

* agent: wait on worker readiness and poll for released handlers in test

Raja SubramanianandClaude Fable 5.1 48700da3f3 sfu: broadcast RTP to down tracks without per-packet allocations (#4875)
* sfu: broadcast RTP to down tracks without a per-packet closure

Every forwarded packet allocated a closure capturing the packet and layer,
and an atomic write counter that escaped with it, even for tracks with a
single subscriber. Add BroadcastRTP, which carries the packet and layer in
the worker state and sums the writes per worker. The serial path no longer
allocates; the parallel path allocates the shared state and the worker
funcval only.

* sfu: reuse the forwarded packet copy in the RED receivers

Both RED receivers copied the ExtPacket (and the opus one the rtp.Packet)
per forwarded packet, and the copies moved to the heap because the
broadcast takes their address. Keep them on the receiver like the existing
redPayloadBuf: ForwardRTP runs on one goroutine and down tracks do not keep
the packet past WriteRTP.

Raja Subramanian 13e4aaec2b Tests for down stream packet push. (#4692)
* Tests for down stream packet push.

A recent issue (padding bit in RTP header) surfaced a gap which slipped
through due to lack of tests. Changes in pion/rtp were not adopted
properly.

So, adding some tests (thank you Claude for the heavy lifting) to test
the down stream packet path using the whole pion chain.

Split out some interfaces so it is easier to have it all in one place
and create fakes.

Will help adding more tests, for example include the upstream path also
in the integration test. May have to create more interfaces and make
things testable, but this is a start.

Raja Subramanian 2c91395055 Propagate spreader threshold to RED receivers. (#4683)
Following up on this PR (https://github.com/livekit/livekit/pull/4678 -
great catch btw, thank you), propagating the spreader threshold to RED
receivers also.

Removing the test as it was a simple case and that would not have caught
the original issue.

Raja Subramanian 3cfb71e7ca Use Muted in TrackInfo to propagated published track muted. (#4453)
* Use Muted in TrackInfo to propagated published track muted.

When the track is muted as a receiver is created, the receiver
potentially was not getting the muted property. That would result in
quality scorer expecting packets.

Use TrackInfo consistently for mute and apply the mute on start up of a
receiver.
