Introduce ConnectionFailedError type.

Delay the CONFERENCE_FAILED event until the user cancels the login
dialog using the 'recoverable' event flag.

It seems that the external API will not send any event to let the sdk
consumer know that the conference has failed if the problem occurs at
the establishing of XMPP connection stage. That's because the config was
loaded successfully, but the conference instance does not exist yet, so
neither base/config nor base/conference will emit any failure.

Make the external API emit CONFERENCE_WILL_JOIN early on SET_ROOM action
which occurs before the XMPP connection is created. At this point we
know that config has loaded and if there's a valid conference room to
be joined. We were thinking of doing that even on CONFIG_WILL_LOAD,
but that seemed to be to risky at this point.

With this the RN component and the consumer app can share same CallKit
provider, configuration, and enable to be part of multiple listeners of
the CallKit flow events. The main driver of this is to enable the
consumer app to be able to report an incoming call to the OS before
loading the JitsiMeetView. Once the user answers the call, the app can
instantiate a JitsiMeetView, pass the CallKit call UUIID, and the Jitsi
Meet components will handle the connection and report back to CallKit
that the  call has been established.

Hristo Terezov, Chris Cordle, and I/Lyubomir Marinov agreed that we'd
try to use "invite" & "invitee(s)" in Web/React's iframe API,
mobile/react-native's SDK invite API, and internally for the purposes of
consistency, ease of understanding, etc.

I'm unsure why all textareas need overflow hidden. Doing so
essentially overrides what I would expect to be standard textarea
behavior. I would rather remove the reset and fix any areas that
have issues.

To be consistent with how the main window toolbar has audio mute,
hangup, and then video mute.

If the beginAddPeople delegate method is implemented, and they haven't been
explicitly set to NO, they willbe YES.

This can happen if there are multiple JitsiMeetView instances are active at the
same time, because there is a single bridge, which means all of them would get
the events.

Currently enterPictureInPicture action can only be dispatched when
the app is on the conference view and the enter PiP button is displayed,
so no check should be necessary.

Activity.enterPictureInPictureMode method must be invoked synchronously
on userLeaveHint callback in order to be sure that the current Activity
is still visible (does not transit to PAUSED state). Previously if the
asynchronous processing would be delayed enough for the Activity to go
into the PAUSED state it will be too late to go into the PiP mode.

To reduce the amount of motion that has to be blurred, use a canvas
to essentially set the FPS of the video background. This canvas
component is behind a temporary feature flag, as well as being able
to disable the blur, so it can be played around with on deployed
environments.

When closing and reopening a notebook, the browser will fire
a devicechange event. This event should not be listened to
after hangup because the current listener will call gum if
there is no current audio/video, which is the case after
hangup.

Initially this change was going to be remove all conference
listeners but then I noticed that the listener for devicechange
is set differently. It might be worthwhile future work, although
potentially unnecessary right now, to ensure all listeners
registered in conference.js are properly cleaned up on hangup.

* Creates conf.d in /etc/prosody if missing.

Fixes a problem installing prosody 0.10 when using prosody repositories.

* Cleanups certificates on purge.

There are various occasions where users purge packages and the new installations after that generate certificate which doesn't end up in the java trust store on the target machine.

* Generate jicofo user and component passwords if missing.

There are situations where if prosody is already installed, the order of configuring the packages is not in the correct order. In those situations jitsi-meet-prosody got configured before jicofo and the user password and the component secret are not available and we ask the user for that and later when jicofo is configured we generate new set of them. Now we will end up always generating them in jitsi-meet-prosody or jicofo and we will reuse them. See https://github.com/jitsi/jicofo/pull/283.

It's required by lib-jitsi-meet when using WebSockets.

- Change copy
- Add labels to dropdowns
- Adjust color and positioning

- Update font files to add new icon.
- Update markup and style so the icon has a small background
  to fill in the text of the icon.
- Remove some css transitions that don't seem to do much.

The app will crash for me with react complaining about not a component
being passed.

* feat(icons): add new recording button icon

* feat(toolbar): show different rec/streaming icon

* Separate local thumbnail in filmstrip

* style(Filmstrip.native): utilize full line length

In order to be able to add analytics to the deep-linking pages the
lib-jitsi-meet initialization has been moved so it happens earlier.

The introduced `initPromise` will eventually disappear, once conference is
migrated into React and / or support for Temasys is dropped. At that stage, it
can be turned into a sync function which all platforms share.

* Button conditionally shown based on if the feature is enabled and available
* Hooks for launching the invite UI (delegates to the native layer)
* Hooks for using the search and dial out checks from the native layer (calls back into JS)
* Hooks for handling sending invites and passing any failures back to the native layer
* Android and iOS handling for those hooks

* Adds in memory log storage, to be used while testing.

Enabling it only when config.debug is set, a configuration provided by jitsi-meet-torture.

* Moves to using config.testing.testMode property for logs storage.

* Fixes comments.

Avoid branching on the same condition and remove unneeded showToolbar call on
filmstrip only mode.
