Change in osmocom-bb[master]: mobile: integrate GAPK based audio (voice) I/O support

Attention is currently required from: Hoernchen, laforge, pespin. Hello Jenkins Builder, Hoernchen, laforge, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmocom-bb/+/30337 to look at the new patch set (#7). Change subject: mobile: integrate GAPK based audio (voice) I/O support ...................................................................... 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 libosmogapk [1][2], which in its turn uses the ALSA sound system for the playback and capture. This is a new optional dependency of mobile, which is automatically picked up if available during the build configuration. Whether to depend on it or not can be controlled using '--with-gapk-io'. The API offered by libosmogapk implies to use the processing chains, which generally consist of a source block, several processing blocks, and a sink block. The mobile app implements the following chains: - 'pq_audio_source' (voice capture -> frame encoding), - 'pq_audio_sink' (frame decoding -> voice playback). both taking/storing TCH frames from/to the following two buffers: - 'tch_fb_ul' - a buffer for to be played DL TCH frames, - 'tch_fb_dl' - a buffer for encoded UL TCH frames. The buffers are served by a new function gapk_io_dequeue().
