* feat(tile-view): initial implementation for tile view

- Modify the classname on the app root so layout can adjust
  depending on the desired layout mode--vertical filmstrip,
  horizontal filmstrip, and tile view.
- Create a button for toggling tile view.
- Add a StateListenerRegistry to automatically update the
  selected participant and max receiver frame height on tile
  view toggle.
- Rezise thumbnails when switching in and out of tile view.
- Move the local video when switching in and out of tile view.
- Update reactified pieces of thumbnails when switching in and
  out of tile view.
- Cap the max receiver video quality in tile view based on tile
  size.
- Use CSS to hide UI components that should not display in tile
  view.
- Signal follow me changes.

* change local video id for tests

* change approach: leverage more css

* squash: fix some formatting

* squash: prevent pinning, hide pin border in tile view

* squash: change logic for maxReceiverQuality due to sidestepping resizing logic

* squash: fix typo, columns configurable, remove unused constants

* squash: resize with js again

* squash: use yana's math for calculating tile size

* feat: Displays the E2E RTT in the connection stats table.

* fix: Whitelists the ping config properties.

* ref: Addresses feedback.

* npm: Updates lib-jitsi-meet to e097a1189e.

* ref: Moves the e2ertt and region to the existing stats object.

* feat(welcome-page): be able to open settings dialog

- Create a getter for getting a settings tab's props so the device
  selection tab can get updated available devices.
- Be able to call a function from a tab after it has mounted. This is
  used for device selection to essentially call enumerateDevices on
  the welcome page so the device selectors are populated.
- Remove event UIEvents.AUDIO_OUTPUT_DEVICE_CHANGED. Instead directly call
  setAudioOutputDeviceId where possible.
- Fix initialization of the audioOutputDeviceId in settings by defaulting
  the audio output device to the one set in settings.

* squash: updateAvailableDevices -> getAvailableDevices, add comment for propsUpdateFunction

* Shows final translated speech to text results as subtitles

* Use conference from redux state and removes addTranscriptMessage

They were required only on Android because of its old JSC version. With the JSC
version bump they are no longer required.

* Moves google-api in its own feature.

* Stores the profile email in redux.

When a call is tarted in audio only mode due to the switch on the welcome page,
the wrong audio mode was chosen.

Use react-native-fastimage, which uses 2 full-native image impleentations using
well known and mature (native) libraries.

This gets us rid of 2 libraries which were observerd as a source of bugs and
created trouble with dependencies: react-native-fetch-blob and
react-native-img-cache. They are also no longer well maintained.

The Image adds a fade effect without asking, so lets explicitly disable
it. More info here:
https://github.com/facebook/react-native/issues/10194

* ref(filmstrip): create an empty container for local filmstrip move

This might be necessary for tile view. To support making the
local video display at the end of remote videos while in tile
view, but separateed from scrollable remote videos, moving
the local video might be necessary. By creating an empty
container, there is a target for local video to move to.

* squash: rename id

* [WEB] add UI for transcription

* add analytics event for button, do not use global APP object

* use props instead of state, use local conference to kick participant

* put imports in alphabetical order

* add translation for TranscribingLabel

* fix merge conflict

* add closed caption button

* purge OverFlowMenuItem which starts and stops Transcription

* readd closed caption icon and fix small issues due to purge

* delete unused icon in _font.scss

* ref(filmstrip): apply filmstrip class to Conference root

Instead of apply the layout class to the body, it can be
applied to Conference. This will allow easier switching
between tile filmstrip and horizontal/vertical filmstrip.

* squash: fix typo filstrip

Move away from middleware and instead update video quality
when the selected video quality updates in redux. This also
lead to removing of automatically exiting audio only because
with the change it's not so readily possible to tell if the
user switched off audio only by re-selecting the already
preferred video quality. Removing this automagic removed
some additional checking done for mobile.

The internal max will be used for tile view. Whatever the
user has set for preferred video quality, the internal
maximum will be respected. This allows for the case where
the user prefers high definition video, but in tile view
it only makes sense to send low definition; ux wise the
user is allowed to continue messing with the video quality
slider.

- "preferred" is being appended because in tile view there is a
  concept of what the user prefers to be the maximum video quality
  but there is also a maximum respected internall. For example,
  the user may prefer HD, but in tile view the tiles may be small
  so internall the preferred would be set to LD.
- "receive" is being renamed to "receiver" to be consistent with
  the naming in lib-jitsi-meet.

* Get back the Notice class
* Add Notice component in the Conference web view
* Notice is not exported in index.js. Only used internally by
  Conference.
* noticeMessage value obtained from features/base/config
  * using mapStateToProps
  * value is stored in the internal _message property
* Notice component, orignal in `toolbox` is moved from
  `toolbox/components` to `conference/components`
* Notice component only implemented and renderable in web views
* Dummy `conference/components/Notice.naive.js`

This patch is partially based in the removed logic included
originally in:

      Toolbar notice as React Component

In reply to: Saúl Ibarra Corretgé @saghul> comments

Signed-off-by: Pablo Saavedra <psaavedra@igalia.com>

* ref(popover): allow for popover content from the right

Popovers contents can display to the left of the trigger
and above the trigger. Add the ability to display to the
right of the trigger my adding mouseover padding. This
may be needed for tile view, depending on where the triggers
are located.

* squash: abstract common css proprties into placeholder class

The previous location no longer exists. This is a fork of the original package,
which is actively maintained.

Fixes: #3304

* fix(welcome-page): css tweaks in prep for branded welcome page

- Watermarks should no longer depend on toolbar size. The left watermark made
  room for the toolbar when the toolbar was on the left side of the screen, but
  the toolbar has been moved to the bottom. The right watermark...well it'll
  clash with the vertical filmstrip but at least the margins will be consistent
  with the left watermark.
- Apply new font-family so fonts are more likely to be consistent across the
  app. Design likes SF UI and keeps requesting it so use it by default.
- Change sizings of welcome page header to be more responsive. This will help
  the header be scrollable when there is no additional content and the header
  overflows.
- Change colors of the welcome page header and remove background image that
  was in the header. Leave in the dom for the background image in case other
  deployments need to continue showing an image.
- Add a period to the title of the welcome page.
- Move watermarks dom location as it is not part of the header; it's part of the
  whole page.

* [squash] Size and font adjustments. Renaming.

* 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

It will only be requested if a user joins a meeting or flips the switch from
video to audio and back, but never as the first thing when the welcome page is
mounted.

It's a separate view (on the native side) and app (on the JavaScript side) so
applications can use it independently.

Small reorganization so other features can send events to the native side.

* Show subtitles when Jigasi sends transcription results in JSON

* fix: Import PropTypes from prop-types.

* apply feedback on initial PR

* Changed Object to Map, alphabetic ordering fixes ,css changes in transcription subtitles

* Sends Map of transcriptMessages as prop to Component

* Documentation fixes and uses config in redux state

* Minor doc fix

* rename feature 'transcription' to 'subtitles'

* Moves subtitles config to interfaceConfig and minor fixes

* minor lint fix

There doesn't seem to be a strong need for the initialized React
Component state in BaseApp so remove/delete it.

BaseApp does all the heavy-lifting related to creating the redux store,
navigation, and so on.

App currently handles URL props and actually triggering navigation based on
them.

Move it away from AbstractApp into an auxiliary function. In addition, introduce
a new `getServerURL` function which gets the configured server URL and defaults
to meet.jit.si as before.

It was never used in practice, and it would be very cumbersome to use, since it
would have to bcreated with all the middlewares and reducers we need. After
discussing this with Lyubomir, we are confident this is not going to be needed
so it can go.
