This is required to get rid of a warning after react native update. See related commit in lib.

None of the breaking changes seemed to affect current
usage of react-i18next and light testing of features
and language switching did not produce issues.

This update is a pre-requisite for removing deprecated react
lifecycle methods, as older versions of react-i18next
have a higher order component that uses the deprecated
componentWillMount, and that issue has been fixed since 7.8.0.

Updates LJM to fix grey overlay with "user is having connectivity
issues" caused by remote track overwrite.

It's impossible to avoid conflicts on a long lived PR like this. Sigh.

- Change "features/chat" to support listening for new chat messages
  and storing them, removing that logic from conference.js.
- Combine chat.scss and side_toolbar_container.css, and remove unused
  scss files. Chat is the only side panel so the two concepts have
  been merged.
- Remove direct access to the chat feature from non-react and non-redux
  flows.
- Modify the i18n translate function to take in an options object.
  By default the option "wait" is set to true, but that causes
  components to mount after the parent has been notified of
  an update, which means autoscrolling down to the latest rendered
  messages does not work. With "wait" set to false, the children
  will mount and then the parent will trigger componentDidUpdate.
- Create react components for chat. Chat is the side panel
  plus the entiren chat feature. ChatInput is a child of Chat and
  is used for composing messages. ChatMessage displays one message
  and extends PureComponent to limit re-renders.
- Fix a bug where the toolbar was not showing automatically when
  chat is closed and a new message is received.
- Import react-transition-group to time the animation of the
  side panel showing/hiding and unmounting the Chat component.
  This gets around the issue of having to control autofocus if the
  component were always mounted and visibility toggled, but
  introduces not being able to store previous scroll state
  (without additional work or re-work).

* feat: Displays the server region in the stats panels.

* feat: Displays the server count in the local stats panel.

* ref: Renames a variable.

* fix: Makes bridgeCount a number, clarifies docs.

* chore: Updates lib-jitsi-meet to 1ac6df97e3.

There are (at least) two changes that are breaking:
- defaultTab is gone
- The re-rendering logic looks to have been re-written so that
  passing in a new array of tabs causes a re-render, which can
  reset the currently selected tab.

The fixes involved removing defaultTab from each tab configuration,
as it is no longer respected anyway. Also, instead of letting Tabs
be uncontrolled and allowing it to set its own selected, which
would result in the first tab automatically being selected on
Tabs re-render, use Tabs a controlled prop to dicate which
tab is selected; this is accomplished by specifying a selected
prop.

This is a pre-requisite to updating atlaskit/tabs to 8.0.8.
Without updating, clicking a dropdown menu within a tab
component within a modal, such as the language selector in
the settings dialog, will lock the browser.

Update the following to the latest:
avatar
button
checkbox
field-text
field-text-area
icon
inline-message
layer-manager
lozenge
modal-dialog (one version before breaking changes)
multi-select
spinner
theme
tooltip

The following were not updated:
- droplist was removed because usage could not be found
- flag was not updated due to regressions with stacking animations
- inline-dialog was not updated because it requires (likely simple)
  fixing of position props

It causes false positives when submitting the app to the Store. Use the new
permissions API in react-native-webrtc instead.

It includes a W3C-ish permissions API which we will leverage.

Fixes a memory leak in Android: https://github.com/DylanVann/react-native-fast-image/pull/214

We are using our fork which is 4.0.14 + the leak fix because the last version
(5.0.3 at the time of this writing) contains a bug that prevents us for using
it: https://github.com/DylanVann/react-native-fast-image/issues/208

Required due to API changes for promises support.

App Store Connect reported the following issues in (and rejected the binary
of) Jitsi Meet 1.18.x:

NSBluetoothPeripheralUsageDescription
NSAppleMusicUsageDescription
NSMotionUsageDescription
NSSpeechRecognitionUsageDescription

Starting spring 2019, all apps submitted to the App Store that access user
data will be required to include a purpose string for the following:

NSLocationAlwaysUsageDescription
NSLocationWhenInUseUsageDescription

PR https://github.com/wmcmahan/react-native-calendar-events/pull/186 has
been merged upstream.

Fixes a crash on Android. Upstream PR: https://github.com/wmcmahan/react-native-calendar-events/pull/186

* Refactor calendar-sync feature to be loaded on web.

For the web part it just adds new property to enable/disable calendar web integration, disabled by default.

* Initial implementation of retrieving google calendar events.

* Initial implementation of retrieving microsoft calendar events.

* Fixes comments.

* Rework to use the promise part of microsoft-graph-client api.

* Moves dispatching some actions, fixing comments.

* Makes sure we do not initializeClient google-api client multiple times.

* Do not try to login when fetching calendar entries.

The case where there is a calendar type google selected, but not logged in, trying to login on loading welcome page will show a warning that it tried to open a popup, which was denied by browser.

* Updates profile display data on sign in.

* Propagate google-api state to calendar-sync only if we use google cal.

* Adds sign out action.

* Clears the event listener when the popup closes.

* Clears calendarIntegrationInstance on signOut.

* WIP: UI for calendar settings, refactor auth flows

* Clean up some unused constants, functions and exports.

* break circular dependency of function and constant

* Exports only isCalendarEnabled from functions.

* Checks isSignedIn when doing fetchCalendarEntries on web.

* address comments

List microsoftApiApplicationClientID in undocument config.

alpha order reducer, return default state on reset

alpha order persistence registry

remove unnecessary getType from apis

update comments in microsoftCalendar

alpha order google-api exports, use api.get in loadGoogleAPI

set jsdoc for google signin props

fix calendartab docs

* Moves fetching calendar from APP_WILL_MOUNT to SET_CONFIG.

The web part needs configuration in order to refresh tokens (Microsoft).

* Fixes storing token expire time and refreshing tokens in Microsoft impl.

* Address comments

updateProfile changed to getCurrentEmail

rename result to results

stop storing integration in redux, store if ready for use

use existing helpers to parse redirect url

* update jsdocs, get google app id from redux

They were required only on Android because of its old JSC version. With the JSC
version bump they are no longer required.

The JSC version used by React Native is about 3 years old, and doesn't implement
things like Symbol or Typed Arrays, which require polyfills. These polyfills are
sometimes a los less performant, as is the case for Typed Arrays.

Bumping an updated JSC version makes both platforms consistent when it comes to
the JavaScript platform.

Use react-native-fastimage, which uses 2 full-native image impleentations using
well known and mature (native) libraries.

This gets us rid of 2 libraries which were observerd as a source of bugs and
created trouble with dependencies: react-native-fetch-blob and
react-native-img-cache. They are also no longer well maintained.
