mobile: integrate GAPK based audio (voice) I/O support
This change introduces a new feature to the mobile application -
audio I/O support, which allows the user to speak right from the
host side running mobile through its ordinary mic and speakers.
The audio I/O is based on libosmo-gapk, which offers ALSA sound
sysyem support. The libosmo-gapk's API implies to use the
processing chains and queue, which basically consist of a source
block, several processing blocks, and a sink block. So, there
are two voice processing chains:
- 'pq_audio_source' (voice capture -> frame encoding),
- 'pq_audio_sink' (frame decoding -> voice playback).
Both of them exchange frames from two dedicated buffers:
- 'tch_fb_ul' - a buffer for to be played DL TCH frames,
- 'tch_fb_dl' - a buffer for encoded UL TCH frames.
In its turn, both buffers are served by a new gapk_io_dequeue()
function, which is being called within the mobile_work() loop.
