...caused by bad state as a result of timing issue around the prejoin flow.

If get user media call is delayed for a while and if user joins
the conference, when it hasn't completed then confrence.js will not assign
'localAudio' and 'localVideo' variables and will create additional media
tracks on unmute operation and add them to JitsiConference via replaceTracks
operation.

Do not resize the desktop share to 720p by default when the desktop track resolution is higher than 720p. This is causing bluriness when presenter is turned on.
Remove the 'detail' contentHint setting for the desktop+presenter canvas stream as it forcing chrome to send only 5 fps stream for high resolution desktop tracks.
Move the desktop resizing logic behind a config.js option - videoQuality.resizeDesktopForPresenter.

There is no need for setting the availability of desktop sharing anymore. It can
now be detected on the spot.

The reson for the previous code was that way back when browser extensions were
needed, it was possible to start a conference without desktopo sharing support
and get it afterwards. This is no longer the case.

Take into account the start muted values stored in local storage.

Through several avatar work iterations it's no longer used.

Adapt to E2EE changes in lib-jitsi-meet. Notably:

---
    e2ee: introduce per-participant randomly generated keys

    This the second stage in our E2EE journey.

    Instead of using a single pre-shared passphrase for deriving the key used for
    E2EE, we now establish a secure E2EE communication channel amongst peers.

    This channel is implemented using libolm, using XMPP groupchat or JVB channels
    as the transport.

    Once the secure E2EE channel has been established each participant will generate
    a random 32 byte key and exchange it over this channel.

    Keys are rotated (well, just re-created at the moment) when a participant joins
    or leaves.

* Adds a dropdown indicator which displays the status of the internet connection.
* It uses the same data as `https://network.callstats.io`.
* The algorithm for the strings displayed to the user is also the one used on `network.callstas.io`.

* ref: Moves xmpp logs to be accessed from connection.

In cases where there is no room like pre-join and lobby screen we still want to be able to debug xmpp messages.

* squash: Updates lib-jitsi-meet.

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

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

* ref: disable ICE restart by default

The reason for that it's currently causing issues with signaling when
Octo is enabled. Also when we do an "ICE restart"(which is not a real
ICE restart), the client maintains the TCC sequence number counter, but
the bridge resets it. The bridge sends media packets with TCC sequence
numbers starting from 0.

The 'enableIceRestart' config option can be used to force it, but it's
not recommended.

* Add dialog to set the E2EE key
* Use the Redux action / middleware to update the key even when set through the
  hash parameter
* Cleanup URL after processing the key so it's not recorded in browser history

Logs the device list when is updated in the reducer and removes
"button enabled" logging which used to dump the device list, but
in a useless way(Object[Object]).

Makes an attempt to log currently selected device, but because of
multiple possible paths it's impossible to find one reliable spot to log
selected device. One has to rely on device list and the GUM call logged
to figure things out.

This effect doesn't modify the media stream, so its safe to start/stop effect and not apply it on the JitsiLocalTrack. This way we can make sure that this effect is not switched out when presenter effect is applied.
