So using V4L2 for audio is not new from this point of view.
Even now I still think V4L2 is the best option, but it looks like there
are a lot of rejects. If develop a new ALSA-mem2mem, it is also
a duplication of code (bigger duplication that just add audio support
in V4L2 I think).

This adds support for the fraction_bits field, used with integer controls.
This allows fixed point formats to be described.
The fraction_bits field is only exposed through VIDIOC_QUERY_EXT_CTRL.
For a given signed two's complement Qf fixed point value 'f' equals
V4L2_CAP_AUDIO_M2M is similar to V4L2_CAP_VIDEO_M2M flag.
It is used for audio memory to memory case.
