wma_decode_end() doesn't exist any more - it was only used to deallocate memory.

Inline wma_window functions. No real performance improvement. Also, thanks to Benjamin Larsson for cleaning up some code I was simply to lazy to fix myself.

Fix rare overflow when decoding MDCT coefficients. As a bonus, decoding is now slightly faster. Thanks to preglow for suggesting I test with a full scale normalized square wave.

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.

Merged in first part of ffmpeg accuracy improvments. No change on my samples, but brings us closer to ffmpeg's source and clears the way for additional bug fixes.

Merged in ffmpeg combined MDCT reconstruction. Saves us a 16KB buffer, and gives a nice speed increase. Brings code much closer to ffmpeg's.

Initial, work-in-progress, version of a WMA codec using Michael Giacomelli's fixed-point and malloc-less WMA decoder (based on the ffmpeg WMA decoder from early 2006, and also building on the work started by Paul Jones). The codec itself and the ASF parsing code were written by me, inspired by the ASF parser in libasf. Current performance is around 400% realtime on gigabeat, 100% realtime on PP and 20% realtime on Coldfire.
