The AudioMixer is now split in a mixer and audio source interface part, which has moved to webrtc/api, and a default implementation part, which lies in webrtc/modules. This change makes it possible to create other mixer implementations and is a first step to facilitate passing down a mixer from outside of WebRTC. It will also create less build dependencies when the new mixer has replaced the old one.
