[build] Bump version.
[sink] Track stream extra devices more carefully.

Count extra routes and do routing change only if there are no streams
with extra route. Prevents skipping audio if multiple streams with same
extra route property are played simultaneously.
Merge pull request #11 from jusa/additional-route

Track stream extra devices more carefully.
Added droid-util headers for 4.4
quick hack for unknown item in audio_policy.conf

global_configuration {
  attached_output_devices AUDIO_DEVICE_OUT_EARPIECE|AUDIO_DEVICE_OUT_SPEAKER
  default_output_device AUDIO_DEVICE_OUT_SPEAKER
  attached_input_devices AUDIO_DEVICE_IN_BUILTIN_MIC|AUDIO_DEVICE_IN_BACK_MIC|AUDIO_DEVICE_IN_REMOTE_SUBMIX
  speaker_drc_enabled TRUE
}
