Move some mpegaudio functions to new mpegaudiodsp subsystem
...
This separation allows these functions to be used in a cleaner
fashion from other codecs (e.g. qdm2) and simplifies creating
optimised versions of them.

This adds a _fixed suffix to the fixed-point versions of things
with both float and fixed-point variants. This makes it more

flag, which appears necessary to playback corePNG P-frames.
