Switch OnMoreData() to use AudioBus.
As titled, with this change we're now piping float data around the pipeline from end to end. This change is in preparation for browser side channel remixing and resampling. As a consequence of this change the shared memory now represents the contents of an AudioBus object, which is essentially audio data in a float planar format. BUG=114700 TEST=Should be no audible change. Ran all existing tests. Compiled ran WebAudio/HTML5/WebRTC on all platforms and PPAPI on Linux.
