It releases the SDK and all dependencies (including React Native) to the
specified Maven repo.

Use an ever increasing number so no manual updates are necessary.

On some Samsung devices the call done with the ConnectionService end up
in the native call history which we don't want. That's fixable by
marking the Connection as "external" just before the call is
disconnected.

Another issue specific to Samsung devices about the audio focus not
always being release when that call ends. That's fixable by marking
the call as holding just before disconnecting it.

They greatly simplify starting a JitsiMeetActivity by encapsulating the creation
of the Intent adn extras placement.

In order to make this possible JitsiMeetConferenceOptions now implements
Parcelable so it can be serialized and passed around when creating an Intent.

Now that we have both a Fragment and an Activity there are lifecycle methods
that overlap. If a Fragment requests permission by calling requestPermissions
then the result handler will be called on itself. React Native's permissions
module, however, calls ActivityCompat.requestPermissions on the Activity, thus
we need to handle the results at the Activity level and not at the Fragment
level.

It's a number whichb must be ever increasing with each build submitted to the
store.

Automate its value by using the number of seconds since 1st of January 2019.
That should be enough for ~680 years.

Turns out that on Samsung phones the calls placed with
the ConnectionService appear in the calls log as weird long numbers.
The system mangles the address we give it ("sip:meet.jit.si/something")
into this weird long number and the call to request.getAddress() returns
that. Turn off the presentation as neither this number nor our address
makes sense. This way the call appears as from "Unknown" caller in call
history which is still not perfect, but better than the random number.

Note that other phones will preserve the originally passed address value
(tested on One Plus 5).

Turns out the microphone will not work on some devices when starting in
"audio only", because the audio mode is not set to the MODE_IN_COMMUNICATION,
but to the MODE_IN_CALL. Calling setAudioModeIsVoip(true) makes
the system adjust to MODE_IN_COMMUNICATION and the mic works fine.

When running the app from Android Studio the React packager is not automatically
started. In vanilla RN projects this is done by the "react-native run-android"
command, but often times it is desired to run from Android Studio.

This fixes that by starting the packager from Gradle.

It's enabled by default, but marked as experimental (uh?!). It creates trouble
as sometimes the packager goes bananas. Disable them until further notice, our
bundle is not that large anyway.

This new version comes with an updated JSC runtime, so we no longer need to
depend on the updated version ourselves.

Consolidate all failure cases into a single one: CONFERENCE_TERMINATED. If the
conference ended gracefully no error indicator will be present, otherwise there
will be.

It renders a single JitsiMeetFragment which holds the JitsiMeetView view.

In practice, we are never going to be in a position where we don't have a
ReactContext but we do have some React Native code running. So let's not expect
the impossible.

It was never used and typicallt the Activity / Fragment holding the
JitsiMeetView object will be the listener.

In addition, once we refactor the events they will be reduced into far fewer.

Add JitsiMeetFragment and refactor the app to use it.

The android.telecom.CallAudioState class was only added in API level 23 (Android
M), so make sure we don't import it in lower versioned devices.

They generate a bunch of harmless yet confusing error messages and they are not
really useful.

We are going to implement the invite dialog *inside* the SDK, so there is no
need to have all this machinery anymore.

* 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

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

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

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