c8da311de4 Fix scaling error that was introduced with r28069. With this fix the level of the hf-spectrum will be correct when decoding aac-he files.

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).

50a6ca39ad Move c/h files implementing/defining standard library stuff into a new libc directory, also standard'ify some parts of the code base (almost entirely #include fixes). 
This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build.

af5bad46d8 Libfaad pow2/log2 improvements: 
Correct pow2_* to calculate correct output for input < 0.0 or between 0.0 and 1.0 instead of returning 0. This will change output, but the float version of this codec uses pow(2.0,x) in place of these functions, so this behavior was probably a bug
Replace 64-bit multiply in pow2_* with left or right shift by whole part of input, rounding if shifting right. An ARM-specific optimized version is provided as a C inline function, other targets use a C macro.
Increase constant size of table for pow2 to improve accuracy, also avoid early truncation in linear interpolation of result.
Move constant tables for pow2 and log2 to iram.

85aad9b397 Extend av_log2 in codeclib into a generic for scanning for set bits, which can provide either log2 or leading-zero-count output, and can force mapping 0 input to 0 output if needed (otherwise 0 input produces undefined result). Replace av_log2 in lib/codeclib.h, floor_log2 and wl_min_lzc in libfaad/common.c and common.h, and count_leading_zeros in libalac/alac.c with macros using bs_generic.

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.

1334738071 Use Tremor IMDCT for WMA. Gives a ~20% speedup on ARM and coldfire. All my test samples gave equivilent or better accuracy (>>16 bit), but there may still be problems. Code becomes somewhat less readable since the IMDCT has bits of Vorbis in it, but this is not a serious issue and the old ffmpeg transform remains in SVN if anyone wants it. Also, WMA now passes Vorbis as the fastest transform codec on ARM, although MPC remains the fastest lossy codec overall.
