+ [WebRTC] Add support for incoming and outgoing libwebrtc audio tracks
+ https://bugs.webkit.org/show_bug.cgi?id=167438
+
+ Reviewed by Eric Carlson.
+
+ RealtimeIncomingAudioSource consumes audio buffers given by libwebrtc.
+ RealtimeOutgoingAudioSource consumes audio buffers from WebCore tracks (capture typically) and feeds libwebrtc with them.
+ To be covered by Layout/mock tests once LibWebRTC peer connection will be added.
+ These are only skeletons right now, the conversion between WebCore and LibWebRTC data is not yet implemented.
+
+ * WebCore.xcodeproj/project.pbxproj:
+ * platform/mediastream/mac/RealtimeIncomingAudioSource.cpp: Added.
