Coldfire DSP Assembly: Fix a bug in the resampler that would only affect one frame on the transition from up to down. Fix a bug in sample output that could be the cause of reported FLAC glitching. Output routines now pass all alignment and size combination tests.

SWCODEC: Tighten up coldfire assembly a little bit more. Cleanup to make differing parameters between ARM and Coldfire halfway clean. Hopefully those differences can be reconciled soon. A tiny bit of C optimizing for karaoke channel mode.

SWCODEC: Dsp speed optimizations. Changes for more modularity. Removal of some usless stuff. Some assembly routines for Coldfire with speed in mind over size for the outputs but the channel modes remain compact. Miscellaneous coldfire asm updates to accomodate the changes. Codec API structure version has to increase so do a full update.

SWCODEC, Coldfire, upsampling: Shave a couple more cycles out of the typical case and I think four bytes. Don't wanna look at this again for awhile. :)

SWCODEC-Coldfire: Small upsampling tweek improves speed and size a tiny bit and prevents unneeded reloading of the previous sample. I imagine it would help most with non-iram source buffers.

SWCODEC: DSP optimizations for conversion to internal format and resampling. Assembly resampling for Coldfire. Word has it ARM will get that soon.

Keep assembler versions of DSP routines in dsp_arch.S files. This also

solves the annoying register allocator problem when not using
-fomit-frame-pointer for the Coldfire assembler optimised crossfeed
routine.
