132bc634ed We removed the old Q15.16 precision trig functions from decoding ages ago, so no need to leave them in. Also, this code needs a GPL header.

877ea486ba Move multiply routines into the header. Give Coldfire a fixmul32b(). Remove some tabs and empty lines.

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.

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.
