The majority of the code is in the WASM file and models, this is just a few KB.
It's so little, in fact, that the performance hint for the main bundle didn't
have to be adjusted.

The error object changed its shape through time, adapt to the change.

Show an overlay with a spinner when slow gUM is fired

When there's no jitsiTrack set on the base/tracks entry it means
a track is being created (get user media is in progress).

This fixes the issue where the local preview appears muted when presenter camera is turned on and then off while screenshare is in progress.

When on prejoin screen, if the device list changes (devices are added or removed),
the newly created tracks do not properly replace the old ones, resulting in
errors after joining the meeting and trying to change the devices.
This change fixes the problem.

- Remove external install dialogs and fix related screensharing error handling.
- Remove obsolete options from config.js and from configWhitelist.js

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.

The resolved promise is expected to return an array.

- Adds the ability to share video as a "PiP" when screenshare is in progress.
- Add a method for creating a local presenter track.
- Make sure isLocalVideoTrackMuted returns the correct mute state when only screenshare is present.
- Make sure we get the updated window size of the window being shared before painting it on the canvas.
- Make sure we check if the shared window has been resized

React Native doesn't define __filename nor __dirname so do it artisanally. In
addition, this helps with centralizing the configuration passed to loggers.

* ref(user-interaction): remove storing of listener

* ref(user-interaction): move browser requirement check to lib-jitsi-meet

* ref(user-interaction): no inner function for listener, use module scope

This only shows up if we cannot prompt again, like when turning permissions off
in the Settings app in iOS.

* fix(conference): require user interaction to unmute in iframe

* squash: explicitly whitelist react native

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

* Fallbacks to use labels for user selected devices.

* Fixes comment.

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.

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.

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.
