* Adds confID to JitsiConference option and enables callstats siteID.

* Simplifies siteID logic and use '/' as default when there is no tenant.

The version change is invoked from add/remove features which controls whether to submit the presence.

* Always uses 8 hex digits for the MUC nickname/endpoint ID.

* squash: Fix a comment and add the full JID to the log.

* squash: Fixes the compilation and style.

They contain no information about the failure (this is available in the onclose
event) and the event references the WS object itself, which causes hangs on
mobile.

Add 'timeSinceLastSuccess' to the details of connection dropped event.

Also do not execute any peerconnection callbacks like
'oniceconnectionstatechange', 'onicecandidate' etc. after close.

Attempts to fix this race condition:
1. Web client joins a conference.
2. Electron client joins the same conference.
3. Web client requests capabilities of Electron
   using version 1111.
4. Electron adds remote control capability,
   settings its version to 2222.
5. Electron responds to web client's requests
   but with features of 2222.
6. Web client caches request under 1111.
7. Any future calls to get features for a client
   with version 1111 will incorrect include the
   remote control capability.

Attempts to fix the following issue:
1. Electron user starts the conference join process.
2. Electron user adds remote control capability and
   attempts to send presence.
3. Electron user presence send is blocked because the
   conference has not been joined.
4. Electron user joins the conference.
5. The remote control capability is not emitted until
   some other presence change triggers another
   presence send. Until then, other uses will not see
   remote control option available for the electron
   user.

* Updates kicked event to inform local and remote kicks and who it affects

* Parses actor from MuteIQ and adds participant info to mute track event.

* Fixes emitting both events.

* Fixes comments.

The idea is to not show the frozen video indication for intermittent
failures which can be confusing to users.

* Removes Edge support.

* Removes unused dependency.

In TraceablePeerConnection: we're no longer injecting a recvonly SSRC
when the local video track is muted, so it's normal that there is no
SSRC found in the local SDP when it's muted.

About RTPStatsCollector: at the time of adding this log statement a case
was missed when local audio track could be replaced in the P2P
connection when a new audio device is selected.

* fix(permissions): remove space from requesting camera

Chrome errors on querying permissions with "camera "
because it does not match an expected enum.

* fix(permissions): check value of returned PermissionStatus

A permissions query returns an object with a status/status
of whether or not permission has been granted. Check that
value in addition to the existence of the object.

* fix(permissions): prevent permission being set to undefined

* ref(permissions): move permissions strings to constants

jitsi-meet-spot currently supports mobile browsers. A
line should be drawn somewhere but maybe not here.
Chrome iOS does not have navigator.mediaDevices so add
a truthy check before checking for getDisplayMedia.

Spot is the consumer of screensharing using a camera
input and through a proxy connection. To differentiate
which one is active, declare a source type on the
created "desktop" stream.

A camera source can be used as a screenshare source.
Normally for screenshare resolution is not capped and
the same will be true for the fake screenshare source.
