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

Fixes datachannels not working.

Fixes an Android crash on craptacular devices.

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

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.

WebRTC is now at M75

https://github.com/react-native-community/releases/blob/master/CHANGELOG.md#v0598

It was extracted from the RN core to a community maintained package.

New M69 build with Metal crash fixes.

Time has come. We need to enable bitcode. It's optional for iOS targets, but
mandatory for the entire project if there is a watchOS target. Since we have a
watchOS target, it's time to enable it.

Fixes a crash on some old Android devices.

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

This is done at the app level, not the SDK.

Currently 2 Firebase services are used:

  - Crashlytics
  - Dynamic Links

They are enabled in tandem, if the appropriate Google services file
(GoogleService-Info.plist on iOS or google-services.json on Android) is found.

Each service needs to be individually enabled in the Firebase console.

Bumping React to 16.6.3 is a requirement for this update.

WebRTC no longer actively fixes iOS 9 issues.

The upstream package has been unmaintained for 2 years now, and making the litle
changes needed as React Native needs them is getting old. The actual
funcionality is a couple of one-liners plus tons of boliterplate, which gets
reduced by quite a bit if we just embed it. So here it goes.
