9e0a7e545f Close both peer connections to aid migration. (#4382)
* Close both peer connections to aid migration.

In single peer connection case, that would close publisher peer
connection.

@cnderrauber I don't remember why we only closed subscriber peer
connection. I am thinking it is okay to close both (or the publisher
peer connection in single peer connection mode). Please let me know if I
am missing something.

And match design to RTP header extension, i. e. the padding for
extensions is not at per extension level (which was the case before),
but has been changed to padding the aggregate of all extensions in this
PR.

b34b047247 Add StopEgress function to the EgressLauncher interface (#4353)

516aeabf45 Use ParticipantTelemetryListener of LocalParticipant. (#4342)
Had made a change in remote participant case to not have telemetry
listener as telemetry does not apply to remote participant. But, that
listener ended up getting used for subscriber and became a null
listener. Use the listener of the subscriber participant for subscribed
tracks.

b81bac0ec3 Key telemetry stats worker using combination of roomID, participantID (#4323)
Some checks failed
Test / test (push) Failing after 17s
Release to Docker / docker (push) Failing after 3m42s
* Key telemetry stats work using combination of roomID, participantID

With forwarded participant, the same participantID can existing in two
rooms.

NOTE: This does not yet allow a participant session to report its
events/track stats into multiple rooms. That would require regitering
multiple listeners (from rooms a participant is forwarded to).

* missed file

* data channel stats

* PR comments + pass in room name so that telemetry events have proper room name also

f3e9b68854 Do not increase max expected layer on track info update. (#4285)
* Do not increase max expected layer on track info update.

When max expected layer increases, the corresponding trackers are reset
so that first packets from those layers can trigger a layer detected
change enabling quick detection of layer start.

A track info update changing max to what is in track info could set the
max expected to be higher without resetting the tracker. And that would
cause dynacast induced max layer change to miss tracker reset too.

Sequence
- dynacast sets max expected to 0
- track info update sets it to 2
- dynacast sets it to 1 --> this should have reset tracker on layer 1,
  but because it is less than current max (2), it is skipped.

* thank you CodeRabbit

08ac4ecdc5 Support preserving external supplied time. (#4212)
In some paths, it is better to preserve pre-recorded time. So, make the
base implementations preserve the RTCP Sender Report receive time.

Also, add a method to enable forwarding packet arrival time. Could be
used across relay.

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.
