Update the version to 0.61.5-jitsi.1 to avoid build aching problems due to the
version not changing.

Fixes datachannels not working.

While Fastlane recommends automagic screenshots, we cannot really do that since
we require a specific setup for a video call and so on.

Since we only support iOS 11, 32 bit architectures must not be built.

This makes it possible to compile the SDK with Xcode 10 and 11. The problem is
that the Google SDK (used for sign-in) is compiled with Xcode 11. This avoids
the issue.

Fixes an Android crash on craptacular devices.

Fixes: https://github.com/jitsi/jitsi-meet/issues/4812

It was introduced in Xcode 9 and made the default in Xcode 10. We were forcing
the use of the legacy version, which doesn't support some new features that we
wish to enable, such as building the SDK for distribution.

Matches the app / SDK deployment target and avoids compilation warnings.

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.

See: https://github.com/jitsi/jitsi-meet/issues/4720

It's available on both Xcode 10 and 11.

The subsystem is set to the bundle ID and the category to "JitsiMeetSDK".

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.

Will emit new 'network.info' action with the online/offline status and
extra details for native like the network type and
'isConnectionExpensive' flag.

This commit refactors device selection (more heavily on iOS) to make it
consistent across platforms.

Due to its complexity I couldn't break out each step into separate commits,
apologies to the reviewer.

Changes made to device handling:

- speaker is always the default, regardless of the mode
- "Phone" shows as a selectable option, even in video call mode
- "Phone" is not displayed when wired headphones are present
- Shared device picker between iOS and Android
- Runtime device updates while the picker is open

* Adds live streaming sound notification.

* Adds ios resources for the new files.

WebRTC is now at M75
