151424a6fd codeclib/libtremor: Clean up duplication of inline funcs, constify the ones in codeclib and copy over the slightly faster MULT31_SHIFT15 from tremor for cf.

85ef10826f codeclib: tweak coldfire mdct asm a bit more, flip usage of mac/msac instead of explicit negation, changes output slightly but is as close to the c version as before. Gives about 0.4MHz speedup of vorbis on cf.

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.

c537d5958e Commit FS#12069 - Playback rework - first stages. Gives as thorough as possible a treatment of codec management, track change and metadata logic as possible while maintaining fairly narrow focus and not rewriting everything all at once. Please see the rockbox-dev mail archive on 2011-04-25 (Playback engine rework) for a more thorough manifest of what was addressed. Plugins and codecs become incompatible.

85e40257dc Enforce that codecs wait for their metadata in a proper-ish and consistent manner. Sort of a halfway patch; best would be to give them an internal copy of the current track information which lasts unaltered by playback until a track switch or unload.

479414facc Fix profiling on coldfire with newer Gcc. 
In switch_thread, make the call to profile_thread_stopped from an inline asm block to make sure the sp is pointing to the right place before storing the context. This apparently worked by luck with the old Gcc.
The workaround used for coldfire in the codeclib's __cyg_profile_func_enter does not work with newer gcc, however the workaround isn't needed for those so enable it only for coldfire gcc version < 4.

a5b17b4511 Rearrange and remove some manual register assignments, make use of pointer address increments for free on arm, and remove macros in favour of explicit inline fns. also add memory clobbers to all uses of stm in inline asm. appears to resolve issues with codeclib failing to work as expected when using ARM_ASM optimisations on targets with native position independent code (e.g. android rockbox targets, but also tremor on non-rockbox targets that has been patched with the fastermdct patches)

46454ac2a8 Move setjmp to lib and add setjmp for sh (imported from newlib) and compile it as separate library. 
It's used by both, plugins and codecs, and sh/hwcodec doesn't compile codecs
so it doesn't fit into sources.

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).

35e8b1429a Rockbox as an application: Replace many occurences of #ifdef SIMULATOR with #if (CONFIG_PLATFORM & PLATFORM_HOSTED) (or equivalently). 
The simulator defines PLATFORM_HOSTED, as RaaA will do (RaaA will not define SIMULATOR).
The new define is to (de-)select code to compile on hosted platforms generally.

Should be no functional change to targets or the simulator.

No modification on pure ARM builds and ARMv5+

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.
