changed to .ajax from .post to allow content type to be set

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

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

* fix(large-video): do not show avatar if no url

By default the large video dominant speaker avatar
has an empty src, which will result in a broken
image displaying. There is also disconnect with
non-react code trying to set an undefined src.
To prevent such until local avatar generation
work is done in the future, just don't show the
avatar.

* fix(conference): set the room instance earlier

Set the room instance on APP.conference before triggering
a redux update of the conference being set,, because
middleware can then fire and call methods on APP.conference
that depend on the room being set.

* get local participant directly from store instead of from global

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 URL cannot end in a /.

e729f0948c contained an off-by-one error:

URI_PROTOCOL_PATTERN includes the colon, so after applyting the regex we are
left with something like '//example.com/room' thus we only need to strip the
first 2 characters.

🤦

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.

* 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

* 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

- 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.

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

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

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.

The class name is similar to the one used for the mute button and is used by the tests to locate and click the button.

This is done to kill off the last deprecated lifecycle
usage. There is special logic within index.native to get a
default meeting url by asynchronously fetching it, if
a url is not passed initially. The url is then put onto
state and overridable on subsequent prop updates.
