Sync codeclib bitstream code with upstream ffmpeg code. Build ffmpeg_bitstream.c as a part of the codec lib. Use this codeclib implementation in libffmpegFLAC. Implement adapted version of the unaligned longword reading optimization for coldfire from the libwma version of this code. Speeds up cook decoding by 2-3% on h300 and flac by 25% on h300, also speeds up flac decoding by 2% on c200 (decoding speed of cook on c200 is unchanged).

Revert r25929. Test have shown that the assembler code is more than 50% faster than the C code both on ARM7TDMI (tested on PP5002 and PP5022) and on ARM1136JF-S (tested on Gigabeat S). If it is slower on ARM9*, it should be disabled for ARM9 only.

flac: remove ARM assembly

2010-05-10T13:01:40+00:00

Using current gcc it only makes decoding a tiny bit slower
Using eabi gcc it makes no speed difference
Tested on fuzev1

Move av_log2 function and asociated table to the codec lib, remove 3 identical implementations, always have LUT in iram (gives a tiny speedup on coldfire), make the clz based function return the same value as the non clz based function for 0 input to be safe (slows down flac ~2% on the gigabeat S)

Use clz instruction to calculate integer logarithms, speeds up decoding of one flac 8 sample by 12%.

Remove some unrequired SIMULATOR checks - the CPU_* family of defines are never defined for the sim.
