A reducer must always return a state or null to ignore it. When the color scheme
is undefined we should return the previous state.

This reverts commit 7c911eca96.

I'm dumb. We need global mode because otherwise lastIndex is not updated in the
regex object, which we rely upon, so this is intentional.

The logMessage can be very long. Probably only it's length could be
important to why sendApplicationLog has failed. Stringify the error
though.

Stores the Logger.LogCollector instance in base/logging state instead of
global APP variable and enables it on mobile.

Looks like custom-scheme links no longer work in all browsers. They do on
Firefox, but the don't in Chrome and other default browsers.

So, switch to intent links on Android:
https://developer.chrome.com/multidevice/android/intents

Example:
```
<a href="intent://meet.jit.si/test123#Intent;scheme=org.jitsi.meet;package=org.jitsi.meet;end">Open Jitsi Meet</a>
```

Dominant speaker events can trigger local participant updates
without a display name. Do not update the name unless there
is an explicit update in the action.

Instead of bundling it in lib-jitsi-meet, which unnecessarily increases
lib-jitsi-meet's bundle size, polyfill it here so it's available in the global
scope, just like the web does.

* fix(local-recording): allow config override to enable

Config overrides are not set until some time after
APP_WILL_MOUNT has completed and not in the same execution
context as when APP_WILL_MOUNT is called. So instead
choose recording controller initialization at a later time.
The time chosen is after conference join because the
controller needs the conference instance to work.

* remove redundant conditional check

Analytics is erroring when unpinning because the logged
event sends null for the objectId. The objectId should
be the id of the person getting unpinned.

This feature is intended for spot. Spot can have an
HDMI -> usb adapter hooked up to it. In that case,
attempting to screenshare should use that adapter
as a screensharing source. Jitsi-Meet should pass
a configured screenshare source into lib-jitsi-meet
so it can be used as a source.

We no longer need it since Rect 16 takes care of passing the context around.
It's also deprecated: https://atlaskit.atlassian.com/packages/core/layer-manager

componentWillMount is a deprecated lifecycle method;
componentDidMount should be used to kick off things
like ajax. In the case of the _App hierarchy, a promise
chain is used to perform initialization, and it is
first started in the constructor by initializing
storage. However, by the time storage is initialized,
resolving the first promise, _App has already mounted.
So, move it all to the componentDidMount lifecycle.

The package now requires using a ModalTransition component
to handle animations. The existing DialogContainer component
has been split into native and web implementations to support
this change.

Updating react-native-fast-image brings a couple of interesting changes:

- onLoad is not called for cached images (reported and ignored upstream)
- load progress not working if component not displayed (on Android)

In order to fix this, a combination of 2 approaches was used:

- onLoadEnd / onError are used to detect if the image is loaded
- off-screen rendering is used on Android to get progress events

While implementing the above, yours truly noticed the complexity was increasing
way too much, so some extra refactoring was also performed:

- componentWillReceiveProps is dropped
- an auxiliary component (AvatarContent) is used for the actual content of the
  Avatar, with the former passing the key prop to the latter

Using the key prop ensures AvatarContent will be recreated if the URI changes,
which is not a bad idea anyway, since the new image needs to be downloaded.

The upstream package has been unmaintained for 2 years now, and making the litle
changes needed as React Native needs them is getting old. The actual
funcionality is a couple of one-liners plus tons of boliterplate, which gets
reduced by quite a bit if we just embed it. So here it goes.

It doesn't seem like videoTrack needs to be set onto state
if it can be accessed directly from props. Removing the state
automatically removes the deprecated componentWillReceiveProps.

Filmstrip remote thumbnails display under certain conditions, as
defined in filmstrip/functions.web.js. Previously the raw
participant count was used, which included fake participants.
Using the selector getParticipantCount excludes fake participants,
causing YouTube thumbnails to remain hidden in a 1-on-1 call.

- Derive the showOverlay state. When the sidebar should be hidden,
  the internal showOverlay state should remain true until the
  animation hides it. When the sidebar should show, the showOverlay
  state should become true immediately.
- Use PureComponent to prevent additional animation triggers
  instead of explicitly checking changes to the "show" prop.

Based on react-native docs, looks like animations should be
started after mount. Updating animation states I'm not certain
on so I moved it to componentDidUpdate and tested with the
live streaming label to ensure the component still animated fine.
