* Initial impl of lobby rooms.

* Fixes tests to check the new fulljid added to MUC_MEMBER_JOINED.

* Updates few of the comments, renaming some functions.

* Renames disableLobby ChatRoom option to enableLobby.

* Fixes a comment.

* Moves setMembersOnly method to ChatRoom.

* Fixes counting members, to exclude jicofo.

* Moves setLobbyRoomJid earlier and renames a method.

Rename _maybeEnableDisable to maybeJoinLeaveLobbyRoom.

* Drops using custom roomconfig lobbypassword field and reuse room lock.

* Handles destroying the lobby room.

* Handles clear lobby room on destroy for moderators.

We do not try to leave the lobby room as it is server-side destroyed and we handle that. The only case of leaving a lobby room is when request to join room is being approved.

* Join main room if lobby is disabled while waiting.

* Adds MEMBERS_ONLY_CHANGED conference event.

* fix: Make sure we leave lobby if main room is joined.

* fix: Setting password when joining locked room.

* fix: Fixes case where we enable lobby for already locked room.

* fix: Fixes case where we enable lobby and then lock room.

* fix: Fixes lint.

* ref: Removes shared password for lobby.

This functionality is handled by the lock room password and handled there.
Removes duplication and unnecessary complicated API for lobby room.

* fix: Fixes comments.

* fix: Skips sending an extra presence on join.

* Renames the variable names.

Add RFC 4588 to the list of advertised features on Firefox.
Use RtxModifier only for cases when simulcast is achieved through SDP munging
This will ensure that RTX is negotiated whenever it is offered by the browser.

removes the SDES mapping. This is a leftover of the time when
Chrome only supported SDES and shouldn't be required anymore.

This has become obsolete thanks to ES6 arrow functions

removing an old FIXME

See: https://chromium.googlesource.com/external/webrtc/+/refs/heads/master/pc/ice_server_parsing.cc#299

follow-up from #1146. Very high level but this should cover the relevant code paths.

The jingle offer was taken from a current focus offer with a few bits removed:
* ssrc-info element
* web-socket element inside transport
* rtcp-mux element inside transport
* bridge-session element
* bundle element (removed in focus already)

and make the code use arrow functions with named parameters in .each()/.map.

Switches from using JitsiConference.isJvbConnectionInterrupted
flag to peerconnection's ICE state. The interrupted
flag is not set if the connection fails initially.

Audio fails on Safari when we try to re-use audio m-lines whose direction has been set to 'inactive'
when the remote source left the conference.
Disable noisy mic detection on Safari as this causes audio input to fail on Safari on iPadOS

removes two unused methods for mangling SDP.

Fixes random tests failures after frameworks upgrade.

A new method which not only has Promise interface,
but also allows to queue IQs regardless of the current
connection's status.

Ping and send ICE failed notification requests are changed
to use this method which makes it more reliable on XMPP
Websocket connections on mobile(which in contrary to BOSH
dies much faster there).

* feat(video-quality): control the sender resolution based on video quality settings

* fix(video-quality): Apply the settings on newly created p2p/jvb jingle sessions
If a p2p/jvb session is not present when setSenderVideoConstraint is called,
make sure the settings are applied when they are created

If ICE config object gets modified while there's any native
PeerConnection instance holding a reference, it will cause
an exception about final object being modified.

It happens when trying to reconnect XMPP Websocket on RN and
is caused by the fact that new TURN config is fetched after
the connection is re-established.

If user experiences any failed reconnect during the entire
session, even if followed by a success, then
the "connectionFailed" flag will trigger
JitsiConnectionEvents.CONNECTION_FAILED on hang up while
processing the disconnected transition.

Get rid of the experimental flag for simulcast support, update js-utils for detecting Edge on Android

Trigger renegotiation only for plan-b when tracks are muted or unmuted

The 'searchParams' are not implemented on react-native.

The LipSyncHack is currently broken in Jicofo and
will lead to unstable behavior.

Switch to using ontrack for remote tracks, re-use mids/transceivers when remote sources are removed and added.

Prevents from calling disconnect on the Strophe
connection if it already has been called or
not connected.

When modifying the room protection (setting or unsetting a password), the muc#roomconfig_passwordprotectedroom should always be defined. This fixes issue #512.

Trigger renegotation only when negotiationneeded event is fired on the browser.
Do not disable simulcast for screensharing in unified plan.
Fix the order of the simulcast streams for Firefox

Use unique session id per TPC.
Translate a=rid to Jingle only when simulcast through RIDs, i.e., ssrc-less simulcast is supported

Send conference.join event only after the peer connection is created.
This way we won't send events for lonely calls.

Copy/paste mistake - there's no such thing as this.connection in
the XmppConnection. Hard to track down because no error is logged.

Either connect or attach can be used to initiate the connection.

Use the rest argument expression to not miss any.

When Jiconop is used to attach to a warmed up BOSH session Strophe goes
to ATTACHED instead of the CONNECTED state.

The LastSuccessTracker has direct access to the Strophe.Connection.

The XMPP stream resumption will enable automatically if supported by
Prosody on Websocket connections. Pass the 'enableWebsocketResume'
config option set to 'false' to disable.

Websocket keep alive is HTTP GET request sent on the service URL passed
to Strophe. It is used to keep the stick tables alive. The feature comes
in enabled by default whenever Websocket are used. Pass
'websocketKeepAlive' config option set to -1 to disable.

See the code for more details about the default interval value.

If Strophe goes to the ERROR state it will pass the error message there
and then transition to the DISCONNECTED state, but without any error
msg.

Given that the XMPP connection is able to reconnect after a drop, now
the jingle session needs to hold off any updates that have to be sent
while the signalling is down. Send the update upon reconnect to sync
Jicofo and JVB with the client's source description.
