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

00e01e82cb Submit FS#11365. Speed up mp3 decoding on ARM processors. It is faster to use the C-implementation of dct32 compiled with -O1 as the asm implementation of dct32 compiled with -O2. Configuration for Coldfire processors is untouched. In the new configuration the stack of the COP decoding thread needs to be increased on dualcore targets. Speed is increasing by up to 0.9 MHz (-O2 against -O1 using eabi).

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.

4e36a2b991 Commit FS#9318 - MP3 synthesis filter on COP. Loads the MP3 synth filer on to the CoProcessor on all PortalPlayer devices, resulting in an ~90% speedup according to test_codec on the Sansa. Real world improvement is somewhat less, but still considerable. Allows MP3 decoding at 30MHz without boosting, or use of more DSP/EQ with less boosting/skipping, thus improving battery life. Minor changes to mpegplayer to retain compatibility with libmad changes. Should be no significant changes for other targets or codecs.

bc97952134 libmad: PP5002 does in fact profit more from -O2 than PP502x, so use it for all targets. The previous check was half-baked (excluded iPod 3rd Gen only, but 1st/2nd Gen are also PP5002).

f52c178517 Revert r14050 (apart from the non-related whitespace changes) and fix the S3C2440 (Gigabeat F/X) problems introduced by my r14041 commit in a slightly different way: Introduce a mad_iram.h file and centralise all IRAM-related decisions in there (similar to how Tremor does it). Now checks for CPU type (S3C2440) instead of target (TOSHIBA_GIGABEAT_F) and there is also a .ibss variable in syth_full_arm.S which shouldn't go in IRAM on S3C2440 targets. Closes FS#7500

66b51909c0 FS #6705 - ARM optimisations for libmad by Tomasz Malesinski. Modified slightly by me to not put code in IRAM for PP502x (it's slower), and for the mpegplayer version of libmad for PP5002 (there isn't enough room). On my ipod Color, it increases a 320kbps MP3 test file from 169% realtime to 188% realtime. Reported speedup on the ipod 3G was from 118% to 155% realtime for a 192kbps MP3.
