This update doesn't touch thousands of lines of package-lock which caused a
runtime breakage on both platforms.

Watch out when updating beyond this version:

Looks like the "Firebase Analytics" dependency is needed when migrating to the
new Firebase Crashlytics SDK. We are only interested in the "latest iversion
crash-free users" stat, which seems to require this. The documentartion is
somewhat confusing though.

We hadn't updated in a while.

It can help catch very weird bugs which are only triggered after a reset.

Use Fastlane to get them from Apple after processing, them upload them.

Also make sure WebRTC dSYMs are included when uploading.

It's back in active development and fixes a warning in iOS.

Rebase our patches (in PR) on top of latest master.

Sshould fix a crash when requesting permisssions.

The dynamic size of it was causing trouble. Fix it by setting a fixed PiP window
size (150px) which makes it consisstent with what we have on Android.

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.
