Commit FS#9318 - MP3 synthesis filter on COP. Loads the MP3 synth filer on to the CoProcessor on all PortalPlayer devices, resulting in an ~90% speedup according to test_codec on the Sansa. Real world improvement is somewhat less, but still considerable. Allows MP3 decoding at 30MHz without boosting, or use of more DSP/EQ with less boosting/skipping, thus improving battery life. Minor changes to mpegplayer to retain compatibility with libmad changes. Should be no significant changes for other targets or codecs.

FS #6705 - ARM optimisations for libmad by Tomasz Malesinski. Modified slightly by me to not put code in IRAM for PP502x (it's slower), and for the mpegplayer version of libmad for PP5002 (there isn't enough room). On my ipod Color, it increases a 320kbps MP3 test file from 169% realtime to 188% realtime. Reported speedup on the ipod 3G was from 118% to 155% realtime for a 192kbps MP3.

Fix build warnings. A better fix might be to define HAVE_LIMITS_H, but someone with a better knowledge of libmad should decide that.
