Raja Subramanian 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.

* Resolve RTX pair via OnTrack also.

In simulcast probing path, the interceptor chain is not invoked
for primary stream. Not sure if this is a recent change. Due to this,
the RTX pair does not get resolved.

Use the onTrack callback to resolve the pair.

* Make data message naming a bit more consistent.

OnDataPacket and OnDataMessage half-way in the chain made it confusing

API still uses SendDataPacket, but that is not harder to read.

Raja Subramanian 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 Subramanian 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 Subramanian 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.

Raja Subramanian 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.

Raja Subramanian bd5382daaa Splitting transport close timeout logs. (#4108)
After adding more fields in
https://github.com/livekit/livekit/pull/4105/files, it was not even
logging. Access to one of the added fields must have ended up waiting on
a lock and blocked.

Unfotunately, the deadlock fix in https://github.com/pion/ice/pull/840
did not address the peer connection close hang.

Splitting the logs so that the base log still happens. Ordering after
looking at the code and guessing what could still log to see if we get
more of the logs and learn more about the state and which lock ends up
the first blocking one.

* Add checks for participant and sub-components close.

Looks like there might be some memory leak with participant sessions not
getting closed properly. Adding checks (to be cleaned up later) to see
if there is a consistent place where things might hang.

aleb_the_flash 27d82a724e Fix "address" typo in transport logs (addddress → address) (#4097)
Correct triple-d spelling of "address" field in transport logs.

I’m not sure whether this was intentional, but I noticed it
while creating Grafana queries and filters. This matters because
anyone filtering logs using the correct spelling may
unintentionally miss relevant data, leading to incomplete or
misleading analysis.
