03e23d1113 Implement error handling for libfaad's memory allocation. Do not allocate PS related types dynamically anymore to minimize code changes.

a602f46d69 Rework of libfaad in several areas. Allow removal of malloc with a new define FAAD_STATIC_ALLOC (in common.h). For now malloc is not fully removed but used by a few arrays needed for AAC-HE SBR+PS only. Reason to keep malloc is to have this amount of memory available for AAC-LC files which might require large m4a tables. The changes make the allocation routines much smaller, better centralized and allow to move duplicated code from aac.c/raa.c to libfaad. The rework includes removal of (now and former) unused code as well.

8033cb6250 Use MEM_ALIGN_ATTR in libfaad. Remove global array and re-use existing one.

20de4c55a2 Fix libfaad error that was introduced with r27225. Noise bursts during playback of several files were reported in the forums.

811af5968a Submit FS#11461. Major speedup for aac he profile (PP5002 +20%, PP5020 +15%, PP5022 +19%, MCF5249 +35%, MCF5250 +80%), still not realtime on most targets though. This change does a lot of refactoring in the sbr filters and the dct, switching to our optimized codeclib fft and tweaking IRAM usage.

52f17dfe9d Submit FS#11445. Speed up of faad (aac) decoder via several optimizations like refactoring some requantization routines, moving several arrays and code tables to IRAM, using an optimized swap32() function and inlining several huffman decoder functions. Decoding is sped up by ~10% (PP5002, PP5022, MCF5249) and ~22% (MCF5250).

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.

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
