Raja SubramanianandGitHub cbb2c61787 Publish/Unpublish counter match. (#4173) 
Published counter was bumped up only when not migrating in, but it was
decremented when a migrating participant leaves without expectation to
resume. That could have resulted in negative counts.

Always change counters irrespective of migration or expected to resume
on leave. Control events send based on migration/resume.

Raja SubramanianandGitHub a26c48304a Add support for RTP stream restart. (#4161) 
* Add support for RTP stream restart.

When an unhandled packet is encountered, try a restart sequence.
Restart happens when 5 packets with contiguous sequence numbers and same
or increasing time stamps are received. Note that this does not work for
B-frame type of scenarios, but that is true for receive path handling
even before this. As WebRTC does not use B-frames, it is fine. But,
needs to be looked at again if B-frames are necessary.

It is controlled by a config that is disabled by default.

Raja SubramanianandGitHub a0a28ac5e3 Avoid duplicate track add to room track manager. (#4152) 
* Avoid duplicate track add to room track manager.

Don't have proof that this happens, but in the leak chase, this is
another component at room level and holds references to tracks. Guessing
this is not cleaning tracks till room is closed.

* add a report

Raja SubramanianandGitHub f01008f876 Revert telemetry stats worker wait configuration. (#4151) 
Mostly reverting https://github.com/livekit/livekit/pull/4148. Leaving
the one bit to pass in a wait time to `Flush`.

Raja SubramanianandGitHub ca4b56d2d5 Handle case of sequence number jump just after start. (#4150) 
It is possible that the stream stops just after start and
restarts much later introducing a large gap in sequence number.
That could look like an unhandled case because the wrap back handler
does not have enough packets yet.

Let other checks based on time stamp gap take effect and only if that
also leaves the sequence number unhandled, drop the packet.

Raja SubramanianandGitHub 1c1a836c3c Mark RTCP buffer Write as noinline. (#4138) 
Seeing a bunch of objects in ReadStreamSRTP.write which does not make
a lot of sense as the function does not allocate anything
(https://github.com/pion/srtp/blob/8fe528a0c4ebb5c46d40a9fd5b77e5b6655fa919/stream_srtp.go#L68-L77)

RTP buffer was marked noinline in an easrlier PR.
Marking RTCP buffer write also as noinline to check if heap reporting
changes.

Raja SubramanianandGitHub 8c241ecf12 Fix RTCP reader leak in DownTrack. (#4131) 
When a participant is closing, RTCP readers should be cleaned up from
factory even if the participant is expected to resume. The resumed
participant will be a new participant session and peer connection(s) and
everything will be set up again.
