8159b9ee9a Faster Q1.31 multiply for ARM. Add some ARM asm windowing code. Simply replacing c code with loop unrolled + load/store multiple instructions makes a surprising difference on PP. Also, add comments to the windowing code.

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

66b51909c0 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.

362f894a53 Sync the bitstream functions with ffmpeg. Switch wmadeci.c over to get_vlc2 which is how ffmpeg now does it and is also slightly faster. Add in defines for later VLC memory usage optization. Kill some header files that weren't needed and update others that were out of sync. We're now much closer to the current ffmpeg codec which should make fixing the remaining issues much easier.

88e32c2fc6 Reorganise the wma_decode_superframe() function - split into a separate init and decode functions. Each call to the decode function now decodes a single frame (2048 samples) instead of an entire superframe (which typically contained about 7 or 8 frames and can in theory contain up to 16 frames). This allows us to replace the 256KB output buffer with a 8KB buffer, and also perform more yields in the main decoding loop.

f5114daa73 Move MDCT reconstruction window code over to new trig function. Improves accuracy significantly and slightly reduces code size. Codec SNR now appears to be limited by truncation to 16 bit. Comparison to MS decoder gives > 91 dB of agreement, and a lower RMS error verses the source wav then MS. Additionally, move one commonly accessed table into IRAM.
