this._room should be used only by jitsi-meet-torture and for test purposes. Also this._room is assigned later than room. This may cause some issues, for example conference.getMyUserId() may return undefined while the user id is already available beacuse this._room hasn't been assigned yet.

* Adds back talk while muted notification.

* Adds unmute button to the notification.

* Adds option to be able to cancel locked rooms and leave.

* Removes not needed operations when canceling password prompt.

Join notifications are already supressed for the local
participant, so hide the left notification. For now
the notification is not being shown on mobile to keep
the same existing behavior and because a copy change
will be needed, but will be added once batching is
implemented.

* Updates kick showing who kicked us.

* Notify participants that someone was kicked.

* Shows notification to user who is remotely muted.

* Updates the notification type.

* Muted by notification for mobile.

* Moves code to react and adds the kick notifications to mobile.

* Updates lib-jitsi-meet.

* Updates start silent, turning on startWithAudioMuted and few UI tweaks.

Disabled mic unmute button and removes remote participants volume slider.

* Adds analytics for start silent.

* Removes extra semi colon.

* Updates lib-jitsi-meet and updates meeting info text.

* fix(recording): do not prompt hidden participants for name

* squash: update package.json

- Use actions to notify the rest of the app that
  a mic or camera error has occurred
- Use middleware to respond to those notifications
  of errors by showing in-app notifications and
  notifying the external api

* Groups devices notifications by type audio/video.

* Fixes passing correct device array.

* Skips setting undefined device id to sink in audio preview.

* Fallbacks to use labels for user selected devices.

* Fixes comment.

The proper field name is "messageType",
not "type." Also using "type" would
override the actionType.

* Fix detecting preferred audio output.

Fixes detecting when a new output device is found and we have stored user preference of using that device.

* Does not store which is the currently open device on save.

Does not save the currently opened device when saving settings dialog, this will be done once we successfully replace the tracks to use the new devices.

* Saves opened audio device after successfully changing it.

If we do it earlier _updateAudioDeviceId is using localAudio and can store wrong value.

* Adds notification for new non preferred devices.

A notification is shown which gives an option to the user to select and use the newly plugged devices.
Adding custom button and handler for the action to the notifications.

* Changes logic to search and handle all newly added devices from array.

* Moves some utility methods to features/base/devices.

When updating the currently used devices always uses the id that is used by the local track instance.

The state about currently opened devices is filtered and not stored, where we only store when user selects a device preferences.
Also allow changing input devices for Firefox when we are not in a conference.

* feat(screenshare): emit source type when starting screenshare

* squash: update doc

When a conference is started, the currently used
camera device id is saved. I believe this is happening
because lib-jitsi-meet does not use exact device id
mathcing when calling getUserMedia, so it's possibl
to request camera A but get camera B back because
camera A is not available. When config.startScreenSharing
is true, the syncing occurs and saves the desktop
source id. So when screensharing is stopped, jitsi-meet
requests that desktop source id instead of the preferred
camera.

* fix(large-video): do not show avatar if no url

By default the large video dominant speaker avatar
has an empty src, which will result in a broken
image displaying. There is also disconnect with
non-react code trying to set an undefined src.
To prevent such until local avatar generation
work is done in the future, just don't show the
avatar.

* fix(conference): set the room instance earlier

Set the room instance on APP.conference before triggering
a redux update of the conference being set,, because
middleware can then fire and call methods on APP.conference
that depend on the room being set.

* get local participant directly from store instead of from global

Stores the Logger.LogCollector instance in base/logging state instead of
global APP variable and enables it on mobile.

* feat(screenshare): support remote wireless screensharing

- Pass events to the ProxyConnectionService so it can
  handle establishing a peer connection so a remote
  participant, not in the conference, can send a
  video stream to the local participant to use as a
  local desktop stream.
- Modify the existing start screensharing flow to accept
  a desktop stream instead of always trying to create one.

* adjust ProxyConnectionService for lib review changes

Delay removing the room reference. This is in case a
consumer of the API is attempting to submit feedback
after hangup but before redirecting to another page.
If the room reference is removed, feedback submission
will fail during this period.

This feature is intended for spot. Spot can have an
HDMI -> usb adapter hooked up to it. In that case,
attempting to screenshare should use that adapter
as a screensharing source. Jitsi-Meet should pass
a configured screenshare source into lib-jitsi-meet
so it can be used as a source.

- Reset some state on the singletons conference
  and VideoLayout.
- Add a way for LocalVideo to clean itself up
  by sharing logic with the other SmallVideos.
- Add clearing of chat messages so they don't
  linger.
- Remove some UI event listeners.

- Change "features/chat" to support listening for new chat messages
  and storing them, removing that logic from conference.js.
- Combine chat.scss and side_toolbar_container.css, and remove unused
  scss files. Chat is the only side panel so the two concepts have
  been merged.
- Remove direct access to the chat feature from non-react and non-redux
  flows.
- Modify the i18n translate function to take in an options object.
  By default the option "wait" is set to true, but that causes
  components to mount after the parent has been notified of
  an update, which means autoscrolling down to the latest rendered
  messages does not work. With "wait" set to false, the children
  will mount and then the parent will trigger componentDidUpdate.
- Create react components for chat. Chat is the side panel
  plus the entiren chat feature. ChatInput is a child of Chat and
  is used for composing messages. ChatMessage displays one message
  and extends PureComponent to limit re-renders.
- Fix a bug where the toolbar was not showing automatically when
  chat is closed and a new message is received.
- Import react-transition-group to time the animation of the
  side panel showing/hiding and unmounting the Chat component.
  This gets around the issue of having to control autofocus if the
  component were always mounted and visibility toggled, but
  introduces not being able to store previous scroll state
  (without additional work or re-work).

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.

Extracts methods which share the common logic. There are still some
leftovers on the web side left which are not used on RN. But this can be
a first step.

The process for doing a replaceLocalTrack is async. Is it
possible to trigger replaceLocalTrack multiple times before
each call is finished. This leads to situations where
replaceLocalTrack is called multiple times with oldTrack being
null and a new track. In this scenario, each new track will be
added, causing UI issues such as the local participant's
large video not displaying for remote participants.

The action replaceLocalTrack is used when unmuting audio or
video, when creating new tracks on device switch, and when
toggling screensharing. These actions can collide with each
other. One way to fix this would be to queue replaceLocalTrack.

This changes a log message from “initialized with %s local tracks 2” to “initialized with 2 local tracks”.

This makes the logs more readable.
