Fix APE 16-bit mono output: mono signals need to be scaled for rockbox.

Get rid of unused return values, except the one from decode_chunk() which will be used in the dual core split.

Compile-time choice between 16 bit and 32 bit integers for the filters. 32 bit filters are faster on ARMv4 (with assembler code), so use them there. Nice speedup on PP and Gigabeat F/X.

Various speedups: (1) Put actual decoding functions into IRAM on PP5002. (2) Put the insane filter buffer into IRAM on coldfire and PP502x (just for completeness, as long as there's no better use). (3) Use the ARMv6 'ssat' instruction for saturation on Gigabeat S.

APE codec: Assembler optimised vector math routines for coldfire. -c2000 is now usable at 130% realtime (was 107%), -c3000 is near realtime (93%, was 64%). -c1000 doesn't change.

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%).

Seeking and resume support for Monkey's Audio

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.
