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.

f51189fa4d Commit FS#11709 by me. Introduces ARMv5E optimized iQMF for atrac3 based on packed multiply instructions. Additionally, improves scheduling on arm9 and arm11 and forces cache alignment of buffers on all targets. Accuracy is slightly reduced, but still greater then 16 bit. Clip+ CPU clock required for LP2 files decreases by 13MHz and ARM11 by 18MHz. No performance or accuracy changes on armv4 or non-arm.

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

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.

2dbb424eb9 Further performance optimization of the atrac3 decoder. Rework the internal sample representation and usage of dsp routines. For now a quick and dirty solution is used to add a fract part of 2 bits. Through this several buffers and functions as well as copy loops could be removed. Furthermore add some ASM for coldfire and place some additional data in IRAM on PP5022/24 and X5/M5. Speedup on ARM: +3%, speedup on Coldfire: +639%. Both ARM and Coldfire can decode in realtime now.
