cd9fc7a2b9 Coldfire assembler version of qmf_synth(). Wideband and ultra-wideband Speex files should see a great speedup. Also add faster and symmetric clipping in iir_mem16().

9d9225ed1d iir_mem16() in assembler for Coldfire for a decent performance boost. Add EMAC init in nb_celp.c, since all modes need this as a base.

86a999c478 Change decoder struct dynamic array members to static arrays sized based on current maximums. Move decoder state structs into IRAM for big speedups This means only one decoder can be instantiated at a time, but that should not be a problem. Tweak Makefile to use -O2 for Coldfire. Update SVN revision info to sync-time revision.

5d066590cc APE codec: Assembler optimised predictor for coldfire. Heavily based on the arm version atm, instruction reordering will probably allow for a bit more speedup soon. Speedup: -c1000: 177% -> 210%, -c2000: 135% -> 147%, -c3000: 97% -> 103%.

2e9c77cc2a APE codec: Further optimised filtering yields 3..4% speedup for -c2000 (now 135% realtime), -c3000 (now 97% realtime) and higher modes. Single 32 bit stores are faster than movem/lea in IRAM.

c13eba29ff FS #7833: Optimizations to the Vorbis codec: 
- ARM assembly version of parts of mdct,
- special case for vorbis_book_decodevv_add for 2 channels and even book->dim,
- store the output in vb->pcm if possible, as it is usually in IRAM as
  opposed to v->pcm.

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.

f52c178517 Revert r14050 (apart from the non-related whitespace changes) and fix the S3C2440 (Gigabeat F/X) problems introduced by my r14041 commit in a slightly different way: Introduce a mad_iram.h file and centralise all IRAM-related decisions in there (similar to how Tremor does it). Now checks for CPU type (S3C2440) instead of target (TOSHIBA_GIGABEAT_F) and there is also a .ibss variable in syth_full_arm.S which shouldn't go in IRAM on S3C2440 targets. Closes FS#7500

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.
