The client now listens for changes to lastN, selectedEndpoints and maxReceiverVideoQuality in redux to trigger sending  bridge message in the new format. This fixes an issue where the stage view <-> tile view changes prompt two receiver constraints messages to be sent, first with the maxHeight update and then with the selected endpoints update.

Set higher preference for screenshare over dominant speaker when trying to elect a participant for large-video. This prevents the dominant speaker from taking over the stage when a user toggles tile view on and off while a screenshare is in progress.

Found via `codespell -q 3 -S ./lang`

* feat: Exposes a method for checking is remote track received and played.

Used for some tests in torture.

* squash: Drop not matching string.

Duplicate translation key with not matching content.

* squash: Moves torture specific functions to features/base/testing.

Listens for media events from the video tag of the large video and stores them in redux.

* squash: Fix comments.

* feat: Listens for media events from the video tag of the remote videos and stores them in redux.

* squash: Fix undefined videoTrack if between switches.

When trying to auto pin screenshare, always select the endpoint even though it happens to be the large video participant in redux. The auto pin screenshare logic kicks in after the track is added.  If the screenshare endpoint is not among the forwarded endpoints from the bridge, it needs to be selected again.

Participants that join video muted do not have video tracks attached. Fixes https://github.com/jitsi/jitsi-meet/issues/7942.

Get the existing HTMLVideoElement for large video instead of creating a new video element for capturing the screenshot.
This should prevent the video player from getting displayed on mobile Safari.

* feat: Allows jvb to control DTLS/SRTP protection profile.

* test: Adds dominant speaker change print for large in testing mode.

Up until now we relied on implicit loading of middlewares and reducers, through
having imports in each feature's index.js.

This leads to many complex import cycles which result in (sometimes) hard to fix
bugs in addition to (often) breaking mobile because a web-only feature gets
imported on mobile too, thanks to the implicit loading.

This PR changes that to make the process explicit. Both middlewares and reducers
are imported in a single place, the app entrypoint. They have been divided into
3 categories: any, web and native, which represent each of the platforms
  respectively.

Ideally no feature should have an index.js exporting actions, action types and
components, but that's a larger ordeal, so this is just the first step in
getting there. In order to both set example and avoid large cycles the app
feature has been refactored to not have an idex.js itself.

Use a dimensions detecting root component. The Dimensions module does not
measure the app's view size, but the Window, which may not be the same, for
example on iOS when PiP is used.

Also refactor the aspect ratio wrap component since it can be taken directly
from the store.

Last, remove the use of DimensionsDetector on LargeVideo and TileView since they
occupy the full-screen anyway.

Fixes PiP mode on iOS.

The playsInline attribute needs to be set to true for video to be rendered on Safari on iOS

It happens when you are drawing into hidden canvas.

It's been considered too disruptive and will often misfire especially
if there are issues with the data channels.

* ref(web): removes video blur when ICE is disconnected.

Removes the blur effect from the large video and stops showing
the network connectivity issues message when ICE disconnects.

The feature has been considered too disruptive and there's a plan to
have it replaced with a more subtle indication.

* remove RECONNECTING key from main.json

This adds an option to disable video autoplay that will be used mostly with maleus (our selenium-based load testing tool for testing the new bridge). Disabling video rendering lowers the resource utilisation of the selenium nodes.

Bring back the workaround introduced in afd2aea7
but removed in 21dcc41d. On conference join,
several other actions have already been fired
that try to set the large video participant
and select the participant on the bridge.
The problem is there is no conference during
these actions so the select participant
never fires. Then subsequent actions do not
fire select participant because the large
video participant has not changed.

🔥🔥🔥

Using anything non-serializable for action types is discouraged:
https://redux.js.org/faq/actions#actions

In fact, this is the Flow definition for dispatching actions:

declare export type DispatchAPI<A> = (action: A) => A;
declare export type Dispatch<A: { type: $Subtype<string> }> = DispatchAPI<A>;

Note how the `type` field is defined as a subtype of string, which Symbol isn’t.

* 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

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

- Create a tile view component for displaying thumbnails in a
  two-dimensional grid.
- Update the existing TileViewButton so it shows a label in the
  overflow menu.
- Modify conference so it can display TileView while hiding
  Filmstrip.
- Modify Thumbnail so its width/height can be set and to prevent
  pinning while in tile view mode.

* use style array for thumbnail styles

* change ternary to math.min for expressiveness

* use dimensiondetector

* pass explicit disableTint prop

* use makeAspectRatioAware instead of aspectRatio prop

* update docs

* fix docs again (fix laziest copy/paste job I've ever done)

* large-video: rename onPress prop to onClick

* change forEach to for...of

* use truthy check fallthrough logic instead of explicit if

* put tile view button second to last in menu

* move spacer to a constant

* the magical incantation to make flow shut up
