This provides an environment for testing out using WebRTC from an iOS extension. It implements a ReplayKit broadcast extension for live streaming games and screensharing. The extension is only supported on iOS 11+ and is guarded by a build flag. Bug: webrtc:9335 Change-Id: Id218d6c73ef7599f5953c5a1e0e62e5d0dc4f10b Reviewed-on: https://webrtc-review.googlesource.com/80000 Commit-Queue: Anders Carlsson <andersc@webrtc.org> Reviewed-by: Patrik Höglund <phoglund@webrtc.org> Reviewed-by: Kári Helgason <kthelgason@webrtc.org> Cr-Commit-Position: refs/heads/master@{#23504}
