0a1baa36b1 Fix FS#10174 by correcting an oversimplification of the AAC window switching code I introduced with the unified IMDCT library. Should significantly improve accuracy for all AAC files.

f5884fdeb6 Disable AAC-SBR, AAC-SSR, and AAC-PS on Sansa clip. Clean up warnings introduced by this. Enable compiling the AAC codec on the Clip. Due to lack of memory for seek tables, files over 10 minutes long or so will probably fail.

46f85c4c54 Combine the Vorbis, WMA and AAC IMDCT functions and put them into the codeclib. Combined IMDCT is now based on existing Tremor transform. Reduces CPU for 192k AAC by 21MHz on Coldfire, and 5MHz on PP5024. WMA and Vorbis should have no functional changes since they already used this code. Further optimization is possible and would benefit all 3 codecs.

999d3e89a8 Put pointer arrays in the correct iram section, tiny const police to make it possible too

db3b70c748 AAC codec: Reduce IRAM usage slightly, to fix the profile builds (on Coldfire).

3fa5e5f592 Apply a bunch of simple AAC decoder optimizations. Biggest speedup is on ColdFire targets, but ARM targets benefits too. Allows realtime playback of some AAC files on Iriver targets (H1x0, H3x0). Remove support for some rarely used AAC profiles to reduce code size a bit.

798a4f3533 Changes to make libfaad compile in Rockbox. Also remove compiler warnings, use some IRAM (IRAM usage needs reviewing) and drastically reduce the stack usage

65de1cc6af Initial check-in of unmodified libfaad (part of the FAAD2 project). This is the last version of libfaad available under the GPL - the state of FAAD2 CVS at midnight on 2005-02-01
