Use the curstom _switchCamera API provided by react-native-webrtc to toggle the
camera instead of destroying the current track and creating a new one.

_switchCamera is implemented at a low level, so the track perceives no changes,
thus being a lot faster and less involved since the capturer doesn't need to be
destroyed and re-created.

In addition, don't mirror the video for the back camera.

When a new local video track is created an associated video capturer is created
for it. The cause for the freezes seems to be creating mutliple tracks (which
come with a video capturer each). Fix this by first disposing of the previous
video track before creating the new one.

Lib-jitsi-meet does not really implement isScreenSharing. Besides,
getCameraFacingMode will already make sure that the video track does not
represent a desktop stream.

This reverts commit e2e04e3f16.

It got broken while rewriting the Web toolbar in React Toolbox. There is
a problem with the toolbars and how we construct the intialState of the
buttons. The _getInitialState() in the toolbox reducer gets the list of
buttons from interfaceConfig, but in fact interfaceConfig is meant to be
overriden in several very important cases. One of the cases being the
external API, which we use in several projects in production.

babel does not modify existing builtins by default. That means
some newer methods, such as Array.prototype.includes, may not
be available unless babel-polyfill is used.

JSDoc comments didn't follow the ESLint rule for properly formatted
sentences.

BTW, I'm not blind to the fact that PasswordRequiredPrompt and
RoomLockPrompt participated in a birthing of source code through
copy+paste. (If we do not copy+paste, we will not have to fix one and
the same source code such as comments  multiple times.)

Queries room for their size or room particiapnt's information. Depends on luarocks net-url module.

fix: P2P address indication

* Uses new peer connection statuses to check and show different user msgs.

Checks for interrupted state of peer connection and shows appropriate messages. In case of inactive or restoring state a message is show to user that video was stopped on purpose. Removes some unused parameters from the event handlers about peer connection status change.

* Removes isParticipantConnectionActive.

Password required dialog (web&native) and native room lock using basic react dialogs.

Moves the P2P indication next to the remote IP address
and rewords it to "(p2p)".

It's no longer needed for building since Node >= 6 already has the minimum
required ES6 syntax. In addition, drop it from app.js since we use Webpack with
the Babel loader to transpile ES5 to ES6.

jsdocs were added, remove old comment which no longer applies.

We (i.e. the jitsi-meet project) are using the haste module system on
Web as well, not only on React Native. Unfortunately, Flow does not
support .web.js by default. Override Flow's defaults to include .web.js
as well. Technically, we have .native.js as well so the choice of
.web.js may lead to errors. Practically though, it is a potential future
problem that we do not have at the time of this writing.

https://github.com/jitsi/jitsi-meet/pull/1397 will take advantage of the
wider Flow use. The PR in question is huge at the time of this writing.
In order to reduce it, I'm extracting changes not directly related to
React-ifying the Toolbar.

https://github.com/jitsi/jitsi-meet/pull/1397 (React Toolbar) is huge at
the time of this writing. In order to reduce it, I'm extracting changes
not directly related to React-ifying the Toolbar such as added jsdocs
and source code formatting.

fix(iframe_api): Passing config params is not working

Fix executeCommand race condition

deps: include styled-components package for @atlaskit components

@atlaskit components will all require styled-components in the
future. Including it now will remove the unmet peer
dependency warning during npm install and prevent future build
breakages that might occur from using a new @atlaskit component
that requires it.

Pull Request #1449

This is in preparation for an upcoming "audio only mode" feature. Setting last N
will also be required for it, so this patch factors out the action and makes it
public so other modules can reuse it.

In addition, if the value is set to undefined the configured default value (or
-1 if absent) is picked.

Moves native dialogs to use dialog container. Implements native Dialog that uses react native Prompt.

All z-indexes found in css files have been moved into css
variables. If the z-index is used only once, the variable
name will be the same as the selector it is used in. If
the z-index is used multiple times, then the plain name
of $zindex# was used. This allowed a more confident
moving down of the toolbar so that the new modal dialog,
with z-index 500, could display on top of it.

Replaces changeAvatarID, changeAvatarURL and changeEmail with
participantUpdated action.
participantUpdated can be fired for local user without id. This
fixes the problem with updating the local user before the user
join the conference which results in fix for failing to execute
commands for avatarID, avatarURL and email right after the iframe
api creates the iframe with Jitsi Meet.

If executeCommand('displayName') is executed before Jitsi Meet
is fully initialized some listeners were not added and the
display name was not changed.

any remote video.

Filmstrip overlays

Fixes settings panel translation.

Strings are not translated when opening the settings side panel. It was that we were creating settings panel html after i18n library had loaded and had translated the rest of the html.
The element selecting the current language was also not translated, which end up with no selection in the UI for the current language.
