Add new APIs for USB audio output device

Add new APIs for USB audio output device

For getting/setting a particular sample format and rate,
a user can use these new APIs below.
  sound_manager_get_supported_sample_formats()
  sound_manager_set_sample_format()
  sound_manager_get_sample_format()
  sound_manager_get_supported_sample_rates()
  sound_manager_set_sample_rate()
  sound_manager_get_sample_rate()

If a user wants to use stream's original sample information
to the USB device without S/W resampling in audio daemon,
these new APIs can be useful.
  sound_manager_set_avoid_resampling()
  sound_manager_get_avoid_resampling()

A user can set the USB device only for media sound. If set
it true, only media type streams can be routed to the device.
  sound_manager_set_media_stream_only()
  sound_manager_get_media_stream_only()
