It hasn't been useful or used in years.

Restarting media session when ICE fails has been working well for some time now.

When a remote user does a ICE restart and a source-remove followed by source-add is received for its sources, mute event on new remote track may not be fired if the old track hasn't been disposed yet.

* feat(conference): Adds a method to request short live tokens.

* squash: Move to ChatRoom.

* feat(conference-request): Attach token to the conference request sent to jicofo.

* squash: Skip adding header when there is no token.

This is the case with permissions reset on backend.

Encoder/decoder issues were noticed with AV1 for Safari. This includes no scalability for the stream that is send, not decoded videos on the receiver side, etc. This should be disable until all issues are resolved.

* fix(conference) Fix different bugs with startMuted policy.
If the user changes mute state after joining the call and before the other participats join the call, make sure those state changes are honored.

* feat(startMuted) Ignore startMuted in Jingle from focus.
Apply startMuted policy based on startMuted setting in room meta data.
Moderator settings and AV moderation settings will now be propagated to new endpoints joining the call through room meta data.
Advertise a new capability 'start-muted-room-metadata' to Jicofo for feature detection.

There is a single implementation of it, so inline it.

Also make sure we only initialize device change listeners once.

We require navigator.mediaDevices.enumerateDevices to exist.

It appears that when the gDM flow is used we do not set properly the sourceId of the shared stream.  When the user has multiple screens we use the sourceId to identify the display that is currently shared. Therefore in electron we can't identify the display that is used and we fail.

Technically anyone can use it as long as they provide connection
options, but we don't need any of that for JaaS.

It's a short-hand for leaving the conference and then disconnecting the
underlying connection.

In the general case (no breakout rooms) this is likely a preferred way
to handle leaving, since there is no good reason to keep the connection
open afterwards.

The bridge is now able to use DD headers for VP8 and VP9 as well so there is no need to remove it from remote desc when the call switches from AV1 to VP8/VP9.
