Workarounds around issue #2037 to have other participants receive the mute event and therefore avoid frozen camera bug

It implements SAS verification as per the Matrix spec, adapted to our environment.

* feat(face-landmarks): add timeline

* add duration to xmpp payload

* Remove support for legacy endpoint based signaling and make source-name signaling as the only signaling mode. The legacy screensharing mode will no longer be supported. The client will still be able to process remote presence sent in the old format to support interop with very old mobile clients and jigasi that do not support source-name signaling.
* remove code related to presenter mode.

fix: corrected error message (see 6810839edc)

Instead of Jicofo signaling all the remote sources available in the call, the bridge now signals only a limited set of SSRCs and then rewrites the SSRC on the outgoing media streams. The SSRC mapping is done based on the sources requested by the clients through the receiver constraints. This limits the number of m-lines in the remote/local SDPs on the client and therefore results in better performance in large calls.

* Handle source remapping messages from bridge
* Added track_owner_changed events
* don't process an invalid rtx ssrc.
* keep track of remote ssrcs, only renegotiate on new ones.
* Change source name on remote track on ssrc remapping.
* Don't remove tracks on member leave.
* Remove (orphaned) tracks on session terminated.
* Use serial number (per media type) to create msid attribute.
* Update videoType on remapping.

This fixes an issue where mute camera operation doesn't stop sending camera stream even though locally it appears to the user that they are muted. This happens when multiple camera streams are added to peerconnection because of how toggle of the video button is implemented. This limitation will be removed when the application is fixed.

Avoid needing an external dependency.

Since Track effects and mute/unmute operations use the same flow, i.e., removing/adding the track from the RTCPeerConnection but not from TPC, make the names of the methods involved more generic.

Since the track is only temporarily removed and added back, it can be treated like mute & unmute operation. Fixes https://github.com/jitsi/lib-jitsi-meet/issues/2048. Remove a TODO thats no longer needed, track replace operation don't force renegotiations anymore.

In most cases it's not a real issue and it's still part of the logs,
throwing an unhandled exception at the global handler just prints an
ugly trackeback in the JS console which looks much worse than it really
is.

* fix(multi-stream): Fix local SSRC cache to include multiple video streams.
If multiple local video streams are found in the SDP, cache all of them instead of the first video SSRC. This fixes an issue where the resolution/fps stats for the screenshare track are not available.

* squash: new track inherits the source name of old track if it exists.

Removing and adding a track back to the conference doesn't generate new source signaling all the time so presence needs to be updated every single time.
Fixes https://community.jitsi.org/t/screen-share-doesnt-work-a-second-time-on-p2p/114024 and possibly https://github.com/jitsi/lib-jitsi-meet/issues/1997.

With just source-name enabled, set the source name of the replaced track before configuring the encodings, this fixes an issues where the sender constraints are not applied on the p2p connection because the source name is undefined.

* fix(video-quality) Update frame heights in content-modify for p2p.
When the user changes the preferred video quality settings from the UI, update the frame height values in content-modify for p2p connection when source-name signaling is enabled.

* fix(multi-stream) Send presence for desktop track before signaling when it is the first track to be added to the conference.
Also do not suppress renegotiation for desktop track on p2p since the browser doesn't fire negotiation needed event.

* squash: fix build

* squash: fix linter issues

* squash: add comment.

When a screenshare track is removed in the legacy mode, presence needs to be sent with the muted state and videoType so the remote gets updated.

* Plumbing for e2e pings.
* linter fixes
* Re-use existing event instead of introducing a new one.

Disable p2p between endpoints that are not running in the same SDP mode. The source-add/source-remove handlers assume the mids to follow the same pattern on both self and peer but the mids generated in plan-b mode are different from unified plan mode. Fixes https://github.com/jitsi/jitsi-meet/issues/11100.

* fix: Set affiliation.

XEP-0045:
Affiliations are granted, revoked, and maintained based on the user’s bare JID, not the nick as with roles.

* squash: Fixes own revokeOwner.

If there are more than one video track at pc creation time, add them sequencially to avoid renegotiation loop.

* Do not send analytics periodically.
* Stop sending e2eping after 5 responses (or 10 requests with no response).
* Pace requests based on conference size.
* Only send e2eping in one direction in a pair of endpoints.

* fix(multi-stream-support) Support muting of desktop track.

* fix(multi-stream) Always initiate responder renegotiation even for p2p.
This is needed since the new m-line is always added to the remote description.

* fix(multi-stream) Support multi-stream only on Unfied plan endpoints.

* fix(multi-stream) Advertise source-name signaling to Jicofo when supported.

* fix(JitsiLocalTrack): Remove unnecessary reject.

* fix: add the correct source name attribute for the second video track.

* squash: Address review comments.

* feat(multi-stream-support) Add TrackStreamingStatus class
update JitsiRemoteTrack to init and dispose TrackStreamingStatus
stop emitting LASTN_ENDPOINT_CHANGED event when source name signaling is enabled
convert TrackStreamingStatus class to typescript

* rename methods and use TrackStreamingStatus enum

* update jdocs for JitsiConferenceEvents.FORWARDED_SOURCES_CHANGED

* feat(multi-stream-support) Adjust presence and videoType message.
Adjust the sourceInfo for all the available local tracks. Do not add handlers for videoType changes on the peer since the videoType doesn't change when multiple stream support is enabled.

* fix(presence) Send the presence in old format for backwards compat.
Send the presence messages in both the old and new format when source name signaling is enabled and sending multiple streams is disabled.

* fix(JitsiConference) Send the videoType bridge msg after mute/unmute op is complete.

* ref(multi-stream-support) Throw if a track is being replaced with a track of different videoType.
This is not supported in the multi sender enabled mode.

* Address review comments.

The encodings for local video tracks are confiugured based on the SenderVideoConstraintsV2 constraints received from the bridge. The constraints are sourceName based. Also ignore enableLayerSuspension flag since it has been deprecated and layer suspension has been enabled by default. Also having it off makes screensharing on Chrome in unified plan not work as expected.

* feat(multi-stream-support) Add the support for multiple local video streams.
This feature is behind 'sendMultipleVideoStreams' config.js flag and is currently supported only on clients running in Unified plan mode.

* squash: Use the track index from source name to find the matching transceiver on unmute.

* feat: Adds events for session-add, session-remove and session-accept.

* feat: Refactor updating presence for audio/video mute and video type.

This brings few changes and fixes. Thew initial presence will always miss audioMuted and videoMuted value, those will be added on session accept. All updates to presence are done on sessionAccept, on source-add or on source-remove and the only one not signalled when camera track is replaced by video track and vice versa.
This change brings more presence updates when number of participants are below startAudioMuted/startVideoMuted, but when participants are above those numbers we get less presence update. This is important for big meetings.
Fixes wrong videoMuted state, as replace track and mute are both executed in promise, sometimes the replace-track one finishes first and when the mute one is resolved there is no conference object in the track to be able to update the presence (hitting this when we pass the startAudioMuted threshold).

* squash: Put back the tracks for _setTrackMuteStatus and _setNewVideoType.

* squash: Fix line length.

* squash: Fix skip sending presence twice.

* squash: Adds the error to the error callback.

* squash: Fix newJingleErrorHandler.
