Verify stack usage of:
- ServiceAudio
- application music player
- decoder worker
Change if possible to a realistic value keeping a 30% margin.
Stack usage reduction is limited due to an extensive stack usage of
every call to the filesystem, which uses around 2 kB of stack.

Audio devices are created in the audio subsystem and it is not possible

Introduce hookable audio device factory to allow sharing bluetooth

Refactor audio module to use only one callback for communication
with audio service. This also simplifies the logic and removes
necessity to define defaults for audio values in multiple places.
