They also need to be applied when changing conferences.

Also, use the configured resolution to set it as the max received frame size.

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.

Android for Enterprise provides special feature for applications to obtain configuration through RestrictionManager remotely by some MDM solution.

Jitsi Meet can be remotely installed and provisioned with a proper URL (making URL not editable by the user) inside the Work Profile or Fully managed device.

720 is requested by default for the local video stream
and when using the quality slider the resolution would
be increased to 1080.

Note that this will limit the receive quality to 720 as well,
because both send and receive constraints are changed at
the same time when the quality slider is used.

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

saghul: torture tests also need it.

When setSubject is called too early we store it as pensing, but thanks to the
default parameter value, if undefined is passed to the function we'll store the
empty string.

This will trigger a needless update because undefined !== ''.

Skip processing any other participant updates.

There are occasions when role to moderator can change a little bit after joining the room, and initial try to set subject will silently be ignored if not moderator.

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 lobby feature adds the possibility to lock a meeting and only allow people in after virtually knocking and going through formal approval

Update userSelectedAudioOutputDeviceId and userSelectedAudioOutputDeviceLabel when a new speaker is selected from the audio settings popup menu

Pass the real deviceId to gUM instead of 'default' for Chrome to return the correct media stream

* fix: Fixes using token with no user context.

* feat(moderated): Adds option to add moderated rooms and subdomains.

When a user joins such room or subdomain in order to be a moderator needs to provide a valid jwt token for that room.

* squash: Renames function.

* ref: Removes filtering jicofo setting owners.

This will be disabled on jicofo side and will greatly simplify logic.
Also check the checks to avoid jwt for main domain to access subdomains and the other way around.

* fix: Skips allowners logic for admins.

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.
