ARM assembler for resampling. Should provide some gains, though not huge ones.

Adapt ARM crossfeed assembler to work like the Coldfire one. Remove SWITCHPARAM cruft as it's no longer needed.

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

Assembler optimised crossfeed routine for ARM. Performance improvement is more than double. Should work fine, but watch your ears nevertheless.

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.
