* Do not send both asb-send-time and twcc.
In single peer connection mode, both extensions are set on the media
engine and both would be negotiated. Unfortunately, pion/webrtc does
not yet support RTPSender.SetParameters() which would allow setting
specific header extensions for the sender. So, check for TWCC enabled
and use it. If not, do abs-send-time if that is enabled.
* check BWE type
* comment
Not sure why only that was applying from req which is effectively a
no-op as the clone is a replica of the req. Guess, it was a typo/miss.
Change it to use room preset config value.
* Handle migration better in single peer connection case.
Have to avoid creating a sender for publish tracks.
Otherwise, the sender messes up the answer SDP because
it forced to inactive and that gets used by type match when setting
remote description offer.
Create sender only for m-lines which was used to send.
* remove unnecessary RemoveTrack
Was breaking migration in cases where there was inactive transceivers
because of direction check.
This change will break single peer connection case, but can look at that
one later.

Not sure how it happens, but seeing a panic caused by no codecs in track
info. Avoiding that and logging information when it happens.

* Populate SDP cid in track info when available.
- Adding SDP cid to TrackInfo. Browsers like FF uses a different stream
id for AddTrack and actual SDP offer. So, have to look up using both
on server side. To make it easier, store both (only if different) in
TrackInfo.
- Use a codec in TrackInfo for audio also. There is some discussion
around doing simulcast codec for audio so that something like PSTN can
use G.711 without any transcoding. So, just keep it consistent between
audio and video.
- Populate SDP cid when SDP offer is received. It could populate a
pending track or an already published track if the new offer is for a
back up codec where the primary codec is already published.
- Passed around parsed offer to more places to avoid parsing multiple
times.
- Clean up MediaTrack interface a bit and remove unneeded methods.

* Send `participant_connection_aborted` when participant session is closed

There is one sticky case. If there is a migration and the migration
fails, this will send `participant_connection_aborted` even though the
participant may have connected properly on the previous node.

Proper message id checks.
Some refactoring for common code in rtcv2service handlers.
Instantiate signalling based on synchronous local candidates flag, but
needs better defined code.
* More v2 signalling changes
- Use wire message in relay signal
- Generate offerId for SDP for sync mode also
- more checks for SDP offer/answer state to see if there are cases of
missed/duplicate messages
* clean up
* Split signal segmenter and reassembler.
As reassembler may need to run a goroutine for pruning, splitting it up
so that we do not have unnecessary goroutines. Keeping the UT unified
though.
Also, for now, trying to see if `Prune` can be called from external
place to avoid creating a goroutine and have extra state/functions to
close the reassembler and clean up goroutine etc. May still have to do
goroutine, but have not created one for now.
* fix: do not increase packetId for each fragment of a packet
