FS#12463: Improve performance for multichannel FLAC decoding. Speeds up decoding by 3 MHz on PP5022, 6-7 MHz on S5L870x and 11-12 MHz on MCF5250. 5.1-88kHz-files still do not decode in realtime on Coldfire and PP502x.

Fix decoding of multichannel flac, refactor sample buffer handling and decorrelation (taken from ffmpeg sources) and add some flac details to the manual. Solves FS#12371.

FS#12231

2011-08-18T16:33:41+00:00

Centralize the selection of codec compilation flags to codec.make
to avoid having to duplicate the per cpu selection logic and the
build rule in the individual codec lib make files and make tweaking
easier.

The two special cases, libmad and libspeex were left alone.

I plan to introduce a var for arm generation so that appropriate flags
can be selected per generation as benchmarking results have shown that
different arm arches might have different optimal flags.

Some of these were found with http://www.samba.org/junkcode/#findstatic. Changes of note:
* The old MDCT has been removed.
* Makefile.test files that create test programs for libatrac, libcook, and libffmpegFLAC have been removed, as they don't work. My project will have a replacement that works with all codecs.
* I've tried not to remove anything useful. CLIP_TO_15 was removed from libtremor because there's another copy (also commented) in codeclib.

Use __builtin_constant_p() to select the best byteswapping method: constant or target optimized. Same macro can then be used for constant values and inits as well as non-constant.

Switch coldfire builds over to new toolchain using gcc 4.5.2 and binutils 2.20.1

Retune codec compiler optimizations with new compiler. Overall speedup with aac and flac getting big speedups.

ffmpeg flac does actually support up to 192k sample rates, and my test file seems to decode fine, so lets enable it. Note that using 192khz is over 6 times slower then 44.1khz on my test file, so I recommend sticking to more reasonable bitrates.
