* ref(large-video): combine selectParticipant logic from web

Currently native/middleware/redux has its own logic for selecting a participant
on the bridge. To have the logic web respect that logic, a few changes are
needed.
- Web no longer has its own call to selectParticipant.
- To keep in line with web logic selectParticipant action should act even when
  there is no track. This makes it so that when a participant does get a track
  that the bridge will send high quality. The bridge can already handle when the
  selected participant does not have a video track.
- The timing of web is such that on joining an existing conference, a
  participant joins and the participant's tracks get updated and then the
  conference is joined. The result is selectParticipant does not get fired
  because it no-ops when there is no conference. To avoid having to make
  uncertain changes (to be lazy), update the selected participant on conference
  join as well.

* squash: update comment, pass message to error handler

* ref(device-selection): do not override var that is not reference again

* ref(device-selection): do not override var that is not reference again

* ref(device-selection): always update known devices on device list update

* ref(device-selection): replace call to get devices from legacy to redux

* ref(device-selection): remove unused device list state from mediaDeviceHelper

* ref(device-selection): update store before updating UI

When replace track is called in JitsiConference, there is no
guarantee a videoType update will come in presence before
the track added event. This can lead to the situation in
LargeVideoManager where an update is called with a track
with an undefined videoType.

Very likely I broke something subtle and I'm prepared to fix it.

- Instead of having 4 listeners for local connection status
  updates and 1 for remote, remove two of the redundant listeners.
- Instead of calling into 4 separate VideoLayout methods to update a
  participant's connection status, expose one handler.

When in audio only, the video should not be shown and instead the
avatar should display.

* ref(video-layout): move middleware for TRACK_ADDED

* ref(video-layout): call mucJoined when redux knowns of conference join

* feat(settings): setting dialog

- Move device selection, profile edit, language select, moderator
  options, and server auth into one modal with tabs.
- Remove side panel profile and settings and logic used to update
  them.
- Pipe server auth status into redux to display in the settings
  dialog.
- Change filmstrip only device selection popup to use the new
  stateless settings dialog component.

* squash: do not show profile tab if not guest

* squash: profile button not clickable if no profile to show

* squash: nits

* ref: Settings dialog.

* ref(large-video): permanently enable canvas based background

* squash: leave flag for disabling background

* ref(toolbar): show recording features based on explicit configs

* squash: bring back button configs, use final config names

* squash: update interfaceConfig comment, remove unused config whitelist

* squash: change order of button enabled checks to reduce diff

* squash: fileRecording -> fileRecordings

Instead of keeping dominant speaker locally, get it from redux and be
updated when the dominant speaker changes. This is in an attempt to mimic
the video layout being reactified and connected to redux.

With so many abstractions called conference, I'm not surprised I made a
mistake and my reviewer didn't catch it.

As we are transitioning from remote participants identified by ID alone
to an ID-conference pair, the subsequent commits "Protect against late
PARTICIPANT_JOINED" and "Refine PARTICIPANT_LEFT for ID collisions"
caught the error.

The commit message of "Associate remote participant w/ JitsiConference
(_JOINED)" explains the motivation for this commit.

The plan set in motion here is to associate remote participants with the
JitsiConference instances that created them in order to be able to
remove remote participants when a JitsiConference is no longer the
primary focus of the jitsi-meet app. And that's supposed to alleviate a
problem with multiplying remote thumbnails.

Doing all of the above in a single commit is a bit of a high order. So
I'm splitting the whole into multiple successive commits for the
purposes of observability, comprehension. Each commit is supposed to be
safe even if subsequent commits are not accepted, are reverted,
whatever. Obviously, without the successive commits, a commit may be
"unused".

One of the important pieces of the multiplying remote thumbnails "fix"
offered is removing remote participants who are no longer of interest
i.e. PARTICIPANT_LEFT. But in order for _LEFT to be implemented, _JOINED
must be implemented first.

Instead of using JS, just use CSS 100% width and height. This
also resolves a jitter that occurs on edge when a modal's
container appends to the body.

* fix(PresenceLabel): Use translated strings for the presence label.

* feat(sounds): Implements loop and stop functionality.

* feat(invite): Add ringtones.

* fix(invite): Code style issues.

* feat(recording): frontend logic can support live streaming and recording

Instead of either live streaming or recording, now both can live together. The
changes to facilitate such include the following:
- Killing the state storing in Recording.js. Instead state is stored in the lib
  and updated in redux for labels to display the necessary state updates.
- Creating a new container, Labels, for recording labels. Previously labels were
  manually created and positioned. The container can create a reasonable number
  of labels and only the container itself needs to be positioned with CSS. The
  VideoQualityLabel has been shoved into the container as well because it moves
  along with the recording labels.
- The action for updating recording state has been modified to enable updating
  an array of recording sessions to support having multiple sessions.
- Confirmation dialogs for stopping and starting a file recording session have
  been created, as they previously were jquery modals opened by Recording.js.
- Toolbox.web displays live streaming and recording buttons based on
  configuration instead of recording availability.
- VideoQualityLabel and RecordingLabel have been simplified to remove any
  positioning logic, as the Labels container handles such.
- Previous recording state update logic has been moved into the RecordingLabel
  component. Each RecordingLabel is in charge of displaying state for a
  recording session. The display UX has been left alone.
- Sipgw availability is no longer broadcast so remove logic depending on its
  state. Some moving around of code was necessary to get around linting errors
  about the existing code being too deeply nested (even though I didn't touch
  it).

* work around lib-jitsi-meet circular dependency issues

* refactor labels to use html base

* pass in translation keys to video quality label

* add video quality classnames for torture tests

* break up, rearrange recorder session update listener

* add comment about disabling startup resize animation

* rename session to sessionData

* chore(deps): update to latest lib for recording changes

To reduce the amount of motion that has to be blurred, use a canvas
to essentially set the FPS of the video background. This canvas
component is behind a temporary feature flag, as well as being able
to disable the blur, so it can be played around with on deployed
environments.

- Change copy
- Add labels to dropdowns
- Adjust color and positioning

Avoid branching on the same condition and remove unneeded showToolbar call on
filmstrip only mode.

* feat(recording): show the YouTube live stream URL

- From the start live stream dialog, push up the broadcast ID
  of the chosen broadcast. It is assumed the ID can be used to
  create the YouTube link.
- Listen for lib-jitsi-meet to emit updates of the known live
  stream URL, shove it into redux, and have InfoDialog display
  it.

* ref(info): pass in dial in and live stream url

Passing these values in should trigger AtlasKit InlineDialog
to re-render and reposition itself.

* ref(info): use conference existence as trigger for autoshowing dialog

* feat(info): add live stream link to invite copy

* Revert "ref(info): use conference existence as trigger for autoshowing dialog"

This reverts commit 1072102267.

* hidden -> url

* _onClickHiddenURL -> _onClickURLText

- old toolbox actions
- chat command processor
- room subject handling

On hangup while audio only, audio only is set to false on
conference leave to reset redux state on mobile. Large video will
update itself on conference leave, but large video has been cleaned
up by that time so trying to directly access the user ID on large
video will fail. Be defensive about this check, because its
callers are already defensive about its return value.

The feature was not ported to the new toolbar. Arguable these
can all be moved into notification but for now simply the
logic will be removed and worked on again as demand arised.

The old toolbar had a dialpad button that did a no-op.
Remove the remnant of that logic.

The flag is always false.

The animate flag is always being passed in as false, so
essentially the animation isn't needed, unless a setTimeout 0
behavior is for some reason required...

jquery animate during animations sets an element's overflow to
hidden and then back to the overflow declared before the start
of the animation. If multiple animations are fired, then the
overflow could be set to hidden permanently. No calls
to Filmstrip#resizeThumbnails have animate set to true, so the
animate call is not even needed.
