* feat(tile-view): initial implementation for mobile

- Create a tile view component for displaying thumbnails in a
  two-dimensional grid.
- Update the existing TileViewButton so it shows a label in the
  overflow menu.
- Modify conference so it can display TileView while hiding
  Filmstrip.
- Modify Thumbnail so its width/height can be set and to prevent
  pinning while in tile view mode.

* use style array for thumbnail styles

* change ternary to math.min for expressiveness

* use dimensiondetector

* pass explicit disableTint prop

* use makeAspectRatioAware instead of aspectRatio prop

* update docs

* fix docs again (fix laziest copy/paste job I've ever done)

* large-video: rename onPress prop to onClick

* change forEach to for...of

* use truthy check fallthrough logic instead of explicit if

* put tile view button second to last in menu

* move spacer to a constant

* the magical incantation to make flow shut up

* Disable buttons only when token features is enabled. Fixes #3355.

* squash: update disabled check.

* squash: update disabled and disabledByFeatures.

* feat(tile-view): exit tile view on pin

* Try out this other ux impl

* Adds dial in default number and pin to the text for calendar/share.

* Handles fail to fetch numbers or conference id.

Since they are a language feature, they make the source code more easily
comprehensible than `if (typeof XXX === 'undefined') { XXX = ...; }`.

The styles.actionColumn does not exist. It looks the same without the
extra View.

Moves NotificationContainer to the toolbox and filmstrip container, so
that there's no need to manually calculate the positions.

The outer container is not necessary if 'justifyContent: flex-end' is
used with the absolute fill on the main container.

Extracts methods which share the common logic. There are still some
leftovers on the web side left which are not used on RN. But this can be
a first step.

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

* Add joing button to the calendar events.

* Add space between calendar lines.

* Adjust recent list name.

* Fixes test failure.

* Restyle mobile recent list message.

* Add analytics events.

Calendar integration ui

The current code was splitting it on a space, which made nicknames such as “Link Mauve” appear as “Link”, whereas it gets displayed correctly everywhere else in the UI.

* Implements calendar entries edit.

Share text generation between calendar-sync and the share-room feature.

* Fixing comments.

* Clone the event element we modify on update.

- navigator.{platform,plugins} were needed by the no longer existing screenshare
  adapter
- document.implementation is already polyfilled by xmldom

If a relative BOSH URL is found (as docker-jitsi-meet does) construct a full URL
based on the location URL and context root.

Also remove some default options since we need the config file anyway, so I see
no point in doing the extra work.

Yours truly refactored routing in https://github.com/jitsi/jitsi-meet/pull/3222
and broke it. When a bare room is entered the pathname was not updated when
applying the default URL.

* 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

- Increase z-index so the subtitles display over tiles.
