* remotes/kraxel/tags/pull-audio-20151215-1:
  audio/coreaudio.c: Avoid deprecated AudioDeviceAdd/RemoveIOProc APIs
  audio/coreaudio.c: Use new-in-OSX-10.6 APIs when available
  audio/coreaudio.c: Factor out uses of AudioDeviceGet/SetProperty
  audio/coreaudio.c: Use new-in-OSX-10.6 API for getting default voice
  audio/coreaudio.c: Factor out use of AudioHardwareGetProperty
