Since these objects will change with reasonable requency, we'll create
many shapes and consume more memory than a Map.

Delete hasAnyVideoTrackWebRTCMuted method as it is not used anymore.

* 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.

The identities are coming from the presence and all values there are string.

* 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.

* feat: Adds a property to JitsiParticipant is hidden from recorder.

When hiddenFromRecorder is enable in config we check the presence for the flag (the jwt identity part).

* squash: Fixes comments.

* feat: Drops unused code about handling incoming caps changes.

* fix: Drop using private fields outside JitsiParticipant.

* fix: Drops unused parameter of join and sendPresence.

* feat: Skips using disco-info for features.

Uses presence to publish features added externally.
Recognizes jigasi participants using a specific presence extension used by jigasi.

* squash: Fixes tests.

* squash: Adds e2ee to the features in presence.

* squash: Fix function name and docs.

* squash: Drops detecting jigasi from initiator.

Using the newly added presence features.

* squash: Drops unused var.

* squash: Fix comments.

* squash: Adds a constant and for E2EEE feature.

...if one is already in-flight.

The code for handling device availability has been disabled for a long time,
plus it's ill named since it represents 2 abstractions: lack of permissions and
lack of devices.

Time for it to rest in the git graveyard.

* Uses optional statsId to report to callstats and push it to presence.

The feature is behind a flag which is disabled by default.

* Renames statsId to statsID.

* Fixes doc.

* feat: multiple, simultaneous RTP stats

Makes it possible to have remote RTP stats running for more than one
peerconnection at a time.

* feat(stats): report RTT all the time

Will report JVB RTT (and end to end) while in P2P mode and vice versa.

* fix(JitsiConferenceEvents): remove CONNECTION_STATS

CONNECTION_STATS event is no longer emitted.

* fix(AvgRTPStatsReported): users with no video

Do not include FPS == 0 in average remote FPS calculation. Report NaN
for local FPS when video muted or no video device. NaN will be reported
for avg remote FPS if no video is received.

* fix(AvgRTPStatsReported): reset total packet loss

* feat(AvgRTPStatsReported): report 'screen' FPS

Will report average FPS for screen videos separately from camera videos,
but only if available (camera video reports NaN FPS when not available).

* fix(AvgRTPStatsReported): end2endRTT

Needs to report JSON with value.

* feat(AVG RTP stats): separate audio and video bitrate

Will report average audio and video bitrates separately.

* doc(JitsiConference): try to improve comment

* fix(AvgRTPStatsReporter): remove confusing reset

There's no a clear reason for doing reset there.

* ref(AvgRTPStatsReporter): rename var

* Adds peer connection statuses (active/inactive/interrupted/restoring).

The peer connection used to be check with is connection active. Adding new states like active, inactive, when the connection was intentionally stopped by the bridge, interrupted due to network problem and restoring, which is the state of a peer which was inactive as being out of lastN and is now entering lastM and eventually will become active.

* Adds timers to track restoring status.

If restoring too long we set the connection status to interrupted. We save timestamps for all participants entering lastN and set the status for the connection to restoring for 5 seconds, or till it goes into active or exits lastN.

* Adds initial connectionStatus of newly created participant - active.

* Fixes some jsdocs.

* Uses symbols for strings and use of map, fixing comments on PR.

* Removes symbols.

The event is triggered when the notification about the user's connection
status change arrives from the JVB.

via presence (via special items with a tag name beginning with
"jitsi_participant_). An events is fired when the value of a property changes.
