Initial commit of Monkey's Audio (.ape/.mac) support. Note that Monkey's is an extremely CPU-intensive codec, and that the decoding speed is directly related to the compression level (-c1000, -c2000, -c3000, -c4000 or -c5000) used when encoding the file. Current performance is: -c1000 to -c3000 are realtime on a Gigabeat, -c1000 is realtime on Coldfire targets (H100, H300 and Cowon), and nothing is realtime on PortalPlayer targets (iPods, H10, Sansa). Hopefully this can be improved. More information at FS #7256.

C optimisations to the predictor decoding - create a single function for decoding stereo streams, and reorganise to minimise the number of variables used. My -c1000 test track now decodes at 93% realtime on PortalPlayer (was 78%), 187% on Coldfire (was 170%) and 447% on Gigabeat (was 408%).

APE codec: Assembler optimised predictor for coldfire. Heavily based on the arm version atm, instruction reordering will probably allow for a bit more speedup soon. Speedup: -c1000: 177% -> 210%, -c2000: 135% -> 147%, -c3000: 97% -> 103%.

vector_math16_arm7.h

Tiny performance improvement for the (not yet usable) compression levels >= -c2000 on ARM7TDMI, utilizing the multiplier's early termination.

vector_math16_armv5te.h

Avoid unnecessary register copies on ARMv5.

|
vector_math16_armv6.h
|
Another minor improvement: better pipelining and one less register used in vector addition/ subtraction.

vector_math16_cf.h

Further optimised the filter vector math assembly for coldfire, and added assembly filter vector math for ARM. Both make use of the fact that the first argument of the vector functions is longword aligned. * The ARM version is tailored for ARM7TDMI, and would slow down arm9 or higher. Introduced a new CPU_ macro for ARM7TDMI. Speedup for coldfire: -c3000 104%->109%, -c4000 43%->46%, -c5000 1.7%->2.0%. Speedup for PP502x: -c2000 66%->75%, -c3000 37%->48%, -c4000 11%->18%, -c5000 2.5%->3.7%
