This reverts commit c9a29153dd.

Now that react-native-webrtc supports the permissions system in 23, use it since
it provides a more pleasant experience to users.

In addition, fix a bug in the previous code: the React Native view must be
loaded after we have acquired the permission to draw on top of other apps,
otherwise our app may crash while we accept the permission, since React may try
to draw.

Remove unneeded css styles

fix an error when testing a result from a method that returns a promise

* feat(local-video): convert to react

- Create a VideoTrack component for displaying a video element.
  This mirrors native also having a VideoTrack component.
- The VideoTrack component does not let React update it to prevent
  the video element from re-rendering, which could cause flickers
  and would not work with temasys's overriding of the video element.
- VideoTrack extends AbstractVideoTrack to mirror native
  implementation and to get the dispatch of the onplaying event.
- Remove the onclick handler on the video element. Honestly, I
  didn't get it to work, and did not try, but it is also unnecessary
  because another handler already exists on the video wrapper.

* ref(device-selection): VideoInputPreview uses VideoTrack to show video

* squash into conversion: change css selectors

* squash into conversion: mix in abstract props

* squash into conversion: change shouldComponentUpdate check

* squash: update comment about why triggerOnPlayingUpdate is used

fix(remotecontrol): Replace info dialogs with notifications.

config.disableDesktopSharing - when set to false will disable desktop
sharing

interfaceConfig.DESKTOP_SHARING_BUTTON_DISABLED_TOOLTIP - when value is
assigned, will not hide the desktop sharing button completely, but show
as disabled with this value used as the tooltip text.

Fix(base.scss): Don't restyle inputs, selects and buttons

feat: Adds TURN indication.

* added checks for audience and issuer values
default audience and issuer checks to validate only appId
added missing documentation lines from the previous PR for context_user and context_group session values

* support for accepting any audience
option set to accept any audience by default

Listeners were set for when a track muted or changed its video
type, but the listeners were never removed. This would could
cause events to keep firing on the removed tracks, which would
cause redux to fire and error because the tracks were no longer
known. That the tracks still fire events after removal is
another issue...

Changes video thumbnail menu icon

stick user and group from token context into session if available

Chrome has deprecated line breaks in requests. The template
literal used for the searchPeople url has a line breaks. Instead
of line breaking the request url, concatenate it together.

Explicitly calls 'updateVideoIconEnabled' in case both audio and video
permission were not granted and device list changed callbacks will not
be executed (check in lib-jitsi-meet that it requires GUM call to
succeed at least once for device list changed events).

Will make an attempt to create video only stream in case microphone
permissions were not granted.

Remove duplication and direct access to kind of private 'state' field by
introducing 'getCurrentContainer' method.

Dynamically enables/disables the toolbar video button. Prior to that
commit if we would start with no video there would be no way to enable
it later on.

Screen sharing video should not be muted if video input device is
disconnected.

Will restore the camera video state from before screen sharing was
started (and will mute it if it was muted).

Do not go back to video from screen sharing if there was no video stream
at the time when screen sharing was being started.

Instead of disabling the video button in the toolbar, mark it as muted,
so that the user can click it to try enable video later on, even if
joined without video (either declined permission or was starting with
screen streaming and dismissed the dialog).

The container needs to store user's ID in order for the 'isOnLargeVideo'
logic to work correctly when user has no stream (previously it was
obtained from stream which can be null/undefined).

* Fix(AddPeopleDialog): Fixes error state and close dialog

* (to-squash) Addresses comments
