FS #7166. Musepack optimizations and cleanups. Huge speedup on ARM. Note that all ARM (Ipod/Sansa/Gigabeat) targets will now play back Musepack files with somewhat reduced accuracy. Please get in touch via forums or Flyspray if you've got sample files where this is very apparent. Most users should hear no difference.
