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.

* feat(Android): implement ConnectionService

Adds basic integration with Android's ConnectionService by implementing
the outgoing call scenario.

* ref(callkit): rename _SET_CALLKIT_SUBSCRIPTIONS

* ref(callkit): move feature to call-integration directory

* feat(ConnectionService): synchronize video state

* ref(AudioMode): use ConnectionService on API >= 26

Not ready yet - few details left mentioned in the FIXMEs

* feat(ConnectionService): add debug logs

Adds logs to trace the calls.

* fix(ConnectionService): leaking ConnectionImpl instances

Turns out there is no callback fired back from the JavaScript side after
the disconnect or abort event is sent from the native. The connection
must be marked as disconnected and removed immediately.

* feat(ConnectionService): handle onCreateOutgoingConnectionFailed

* ref(ConnectionService): merge classes and move to the sdk package

* feat(CallIntegration): show Alert if outgoing call fails

* fix(ConnectionService): alternatively get call UUID from the account

Some Android flavours (or versions ?) do copy over extras to
the onCreateOutgoingConnectionFailed callback. But the call UUID is also
set as the PhoneAccount's label, so eventually it should be available
there.

* ref(ConnectionService): use call UUID as PhoneAccount ID.

The extra is not reliable on some custom Android flavours. It also makes
sense to use unique id for the account instead of the URL given that
it's created on the per call basis.

* fix(ConnectionService): abort the call when hold is requested

Turns out Android P can sometimes request HOLD even though there's no
HOLD capability added to the connection (what!?), so just abort the call
in that case.

* fix(ConnectionService): unregister account on call failure

Unregister the PhoneAccount onCreateOutgoingConnectionFailed. That's
before the ConnectionImpl instance is created which is normally
responsible for doing that.

* fix(AudioModeModule): make package private and run on the audio thread

* address other review comments

supports a '*' in the sub claim to allow access to any room

This marks our switch to CalVer: http://calver.org/

Major: year
Minor: release number
Patch: build (in case we need to retry)

* 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

This makes Dropbox work on apps using the SDK without needing to build it
themselves.

- remove unneeded dialog (it's taken care of by StartRecordingDialogContent)
- pass correct props so integrations (Dropbox) show up

While Apple doesn't want to allow us to enable Dropbox, it's good to have it
available for testing.

Load it at build time from a "dropbox.key" file. The file should contain the API
key in a single line.

* feat(screenshare): support remote wireless screensharing

- Pass events to the ProxyConnectionService so it can
  handle establishing a peer connection so a remote
  participant, not in the conference, can send a
  video stream to the local participant to use as a
  local desktop stream.
- Modify the existing start screensharing flow to accept
  a desktop stream instead of always trying to create one.

* adjust ProxyConnectionService for lib review changes

There was a missing delegate method call into RNGoogleSignIn, which fixed this.

I'm ashamed to admit that I spent several _days_ chasing a bug that was already fixed. :( This obvious instruction would have been a time-saver.

Delay removing the room reference. This is in case a
consumer of the API is attempting to submit feedback
after hangup but before redirecting to another page.
If the room reference is removed, feedback submission
will fail during this period.

These values must match these ones in React Native:
5939d078a0/ReactAndroid/src/main/java/com/facebook/react/modules/systeminfo/AndroidInfoHelpers.java (L20-L22)

Used for building and deploying builds to TestFlight and the App Store.

Read it from the GoogleService-Info.plist file and apply it into Info.plist.

No caps are allowed, so this would trigger a rejection when uploading to
TestFlight.

- unpin participant (if the local one was pinned it would remain)
- close any dialog (except if authentication is pending)

feat(screenshare): use camera as a screenshare source
