- Adds the ability to share video as a "PiP" when screenshare is in progress.
- Add a method for creating a local presenter track.
- Make sure isLocalVideoTrackMuted returns the correct mute state when only screenshare is present.
- Make sure we get the updated window size of the window being shared before painting it on the canvas.
- Make sure we check if the shared window has been resized

* Adds an option to set email through iframe API init and to stats.

* Simplifies configuring email and displayName in stats.

Removes enableStatsID as not needed as when off we are sending as callstats id xmpp resource which is unique per call and id must be something that sticks between calls (callstatsUsername).

* Adds email and displayName in stats config for mobile.

* chore(deps): Updates lib-jitsi-meet to latest dd31f0a.

* Removes enableStatsID from config and whitelist.

It crashes on Android. Well, on the JSC version React Native uses on Android.

While we could use this fallback only on Android, we have decided to use it
on all mobile platforms for consistency.

iOS 10 crashes, so don't use it there, in any case.

Currently only 2 options are implemented, mainly aimed at helping troubleshoot
audio related problems:

- Disable native call integration (it disables CallKit / ConnectionService)
- Disable P2P

We are downloading code off the Internet and executing it on the user's device,
so run it sandboxed to avoid potential bad actors.

Since it's impossible to eval() safely in JS and React Native doesn't offer
something akin to Node's vm module, here we are rolling our own.

On Android it uses the Duktape JavaScript engine and on iOS the builtin
JavaScriptCore engine. The extra JS engine is *only* used for evaluating the
downloaded code and returning a JSON string which is then passed back to RN.

None of them work on mobile.

- use AbortController for setting the fetch timeout
- use async / await syntax for clarify
- set the default timeout to 5s (previously non-existent, aka 0)
- add ability to load but not evaluate a script

They never worked on mobile and pose an impediment for makinf config.js more
future proof. Specially if we want to move to a non-executable form of
configuration.

For now all keys are whitelisted.

This adds an option to disable video autoplay that will be used mostly with maleus (our selenium-based load testing tool for testing the new bridge). Disabling video rendering lowers the resource utilisation of the selenium nodes.

It crashes like hell. See:
https://bugs.chromium.org/p/webrtc/issues/detail?id=11002

We try to load the configuration with every room change, even when there is no
room. There is a bad (corner) case: when we have no config cached (first boot or
wiped app data). In such case the user is trapped in an infinite loop because we
require the config to show the welcome page, oh well.

Pretend we have a configuration by creating the most minimal one to at least get
to the welcome page.

There are just a couple of logs in this feature, and it's included in bundles
like external_api, which would bloat it due to cascaded dependencis.

These provide the ability to integrate the SDK with some other application
loggers.

At the time this was written we use Timber on Android and CocoaLumberjack on iOS.

In addition to the integration capabilities, a LogBridge React Native module
provides log transports for JavaScript code, thus centralizing all logs on the
native loggers.
