Updates also to latest react-callstats 3.27.0 as lib-jitsi-meet already updated to it.

https://github.com/DylanVann/react-native-locale-detector/pull/3

* Removes unused config logic.

* Whitelists config options that can be overridden using the URL.

* Recorder login with credentials, not supported by externalconnect.

Jibri uses xmpp credentials to login, which is not supported by externalconnect, so we want to skip it till that is supported.

* Whitelist only config.js

* Extracts whitelisting in separate function.

* On adding participant show the initial status text if any.

When participant joins and there is an initial status we show it, instead of the connected notification. If initial status is missing proceed with the default user connected notification.

* Updates to latest lib-jitsi-meet (365bd886ee).

* Adds a fixme comment.

It was decided along with the mute participant dialog reactification
that these types of warning messages should not be toggleable--that
they should simply always display because there is no undo action.
As such, the component NotificationWithToggle is no longer needed.

It's possible for a track to be disposed but still on the redux store, before
the reducer removed it.

After looking at the jquery-ui documentation, I believe it
is being used only in one place, when toggling the smiley
menu. That toggling has been quickly replaced with a normal
jquery call.

Note: @atlassian/aui also uses jquery-ui but killing that
off will be more difficult due to its CSS being used.

That standalone ButtonGroup package has been deprecated.
The deprecation warning says to use the ButtonGroup component
from the Button package.

* feat(keyboard-shortcuts): show help in a react dialog

- Move shortcut help dom declaration to a react component
- Let open/close logic be handled by AtlasKit Dialog
- Remove static html for help from index.html
- Consolidate keyboard shortcut css

* squash: use lozenge for key styling

* squash: use different iteration style

* squash: update package-lock for lozenge

It seems to me that npm 5 starting adding github: as the protocol of
dependencies in package.json which are from GitHub. I personally don't
know which npm version supports these and whether we care about such a
support. Anyway, having some use github: and most not is not consistent.

Everything strophe related is now handled in lib-jitsi-meet project.

ESLint 4.8.0 discovers a lot of error related to formatting. While I
tried to fix as many of them as possible, a portion of them actually go
against our coding style. In such a case, I've disabled the indent rule
which effectively leaves it as it was before ESLint 4.8.0.

Additionally, remove jshint because it's becoming a nuisance with its
lack of understanding of ES2015+.

This commit adds initial support for CallKit on supported platforms: iOS >= 10.

Since the call flow in Jitsi Meet is basically making outgoing calls, only
outgoing call support is currently handled via CallKit.

Features:
 - "Green bar" when in a call.
 - Native CallKit view when tapping on the call label on the lock screen.
 - Support for audio muting from the native CallKit view.
 - Support for recent calls (audio-only calls logged as Audio calls, others show
   as Video calls).
 - Call display name is room name.
 - Graceful downgrade on systems without CallKit support.

Limitations:
 - Native CallKit view cannot be shown for audio-only calls (this is a CallKit
   limitaion).
 - The video button in the CallKit view will start a new video call to the same
   room, and terminate the previous one.
 - No support for call hold.

The global.performance.now polyfill is removed since it's polyfilled by
react-native-callstats.

callstats no longer depends on it and it doesn't break when we use the latest.

As https://facebook.github.io/react/docs/typechecking-with-proptypes.html
says, React.PropTypes have moved into the npm package prop-types since
React v15.5. I've already failed to update certain devDependencies
because they mandate the use of prop-types so I'd rather we (gradually
at least) move to prop-types rather than face a lot of work later on.
