audio: refactor: work towards unentangling audio decoding and filtering

Similar to the video path. dec_audio.c now handles decoding only. It
also looks very similar to dec_video.c, and actually contains some of
the rewritten code from it. (A further goal might be unifying the
decoders, I guess.)

High potential for regressions.
