Mpegplayer: Assembler optimised IDCT for coldfire, based on FS #5995 by Karim Boucher. Put the IDCT block buffer in IRAM for better performance. The whole libmpeg2 decoder struct doesn't fit without throwing some libmad buffers out of IRAM, but then doesn't change performance significantly. Mpegplayer is quite usable now on X5; H300 is sort-of usable for widescreen.
