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.
