This table is probably 128 entries long beginning with -60. Greatly improves FS#7488, but does not entirely fix it. Also, while I'm recomputing tables, use proper whitespace formating.

Increase the size of one of the look up tables. Fixes 'burst of static' in some files. I still have no idea how big it really needs to be...

Apparently, negative exponents are possible when decoding exponential VLC. Should fix occasional glitches that happened in files of all bitrates.

Initial attept at supporting Line Spectral Pairs. Various issues remain, and the ffmpeg decoder itself often fails on certain valid LSP files. Expect some issues.

Add incomplete support for files using noise coding but not LSP. In practice, this means files >= 20kbps will probably work, and those below will probably not.

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.

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.
