2e6d604bb6 Stop hiding errors by redirecting stderr to /dev/null. If we really need to do re-introduce somewhere we should rather make it dependent on the V variable so that make V=1 would still show the error and only "normal" builds would hide it.

953348f1ba 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.

c78b019944 I figured out what was *really* causing the MPC track-change noise, so I 
backed out Thom's change and made the appropriate change. Note that this
should not fix the track change *pop* because there still seems to be a
problem decoding the first and last several hundred samples of MPC files.
