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.

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

Since this is a feature implemented in the SDK, it makes sense that all the
plumbing required to make it work it's in the SDK itself.

This makes the PermissionsAndroid builtin module work.

Introduce the JitsiMeetActivityInterface, which defines the interface that
activities using JitsiMeetView directly must implement in order to ensure full
functionality.

Queue replaceLocalTrack

The process for doing a replaceLocalTrack is async. Is it
possible to trigger replaceLocalTrack multiple times before
each call is finished. This leads to situations where
replaceLocalTrack is called multiple times with oldTrack being
null and a new track. In this scenario, each new track will be
added, causing UI issues such as the local participant's
large video not displaying for remote participants.

The action replaceLocalTrack is used when unmuting audio or
video, when creating new tracks on device switch, and when
toggling screensharing. These actions can collide with each
other. One way to fix this would be to queue replaceLocalTrack.

The instance variable is not accurate. By default isVisible is
set to false but nothing sets the video container to actually
not be visible. As such it is possible for the video element
itself to autoplay, thereby making video visible, while the
isVisible boolean is still false. The fix chosen is to remove
instance variable and always respect calls to show/hide so
that the video container can be set to hidden.

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

The border changes the tile sizing, due to box-sizing, and that
messes with the video aspect ratio.

Required due to API changes for promises support.
