07405841c6 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.

b086458e4e FS#12231 
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.

4909e09267 FS#12141 by Sean Bartell 
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.

b965c24c0b 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.

f32294d6ab Shorten: tweak some inline asm, use local lables to not cause problems when the function gets inlined, mark it as inline, tweak clobbers and use lea instead of add in one place. Fixes problems when building libffmpegFLAC with newer gcc.

a87c61854e 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).

45c7498f59 FS#11335 by me: make ARM assembly functions thumb-friendly 
We can't pop into pc on ARMv4t when using thumb: the T bit won't be
modified if we are returning to a thumb function
Code running on ARMv4t should use the new ldrpc / ldmpc macros instead
of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc}
No modification on pure ARM builds and ARMv5+

Note: USE_THUMB is currently never defined, no targets can currently be
built with -mthumb, see FS#6734

e02ceefdbc Submit FS#11381. Use -O2 for ffmpegFLAC on ARM targets. This will give reasonable speed-up (+3% on PP502x) for svn and major speed-up when switching to eabi tool chain (+9% on PP502x). Coldfire was tested to be faster when keeping -O1.

08d3c0be37 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.

0a1d7c28b7 Make open() posix compliant api-wise. A few calls (those with O_CREAT) need the additional optional mode parameter so add it. Impact for the core is almost zero, as open() is a wrapper macro for the real open function which doesn't take the variable parameter.

2e6d604bb6 Stop hiding errors by redirecting stderr to /dev/null. If we really need to do re-introduce somewhere we should rather make it dependent on the V variable so that make V=1 would still show the error and only "normal" builds would hide it.
