Reorganize Audio Files & Name Remaining Audio Files (#1494)

* reorganize audio files

* audio code files

* split audio and libaudio

* audio_init_params to audio_configuration

* simplify file names

* move aisetnextbuf to libaudio

* move src/audio -> src/code/audio

* adjust makefile comment

* reorganize again into internal/external

* adjust comment

* restructure again
