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.

8ed7bda64c Move udiv32_arm.S into libdemac, as this divider is specialized for the APE codec and an optimized divider is already provided for general use in codeclib.

bff5a35c3c FS#10943, optimized division and clz routines to replace libgcc routines for ARM. Replaces libgcc support functions for unsigned and signed 32-bit division on ARMv4 and up, and leading-zero count on ARMv4.

e76f30a57c Improvements to specialized dividers for APE codec: 
* Use Newton-Raphson divider on ARMv5e and ARMv6, about 7% speedup on Gigabeat S.
* On ARMv4 targets using IRAM, remove insane filter buffer from IRAM, fill available IRAM with LUT of reciprocals for small divisors - speedup varies according to target and available IRAM, APE normal sample is approx. 109% RT on e200.
* Rename apps/codecs/lib/udiv32_armv4.S to apps/codecs/lib/udiv32_arm.S, which includes dividers for all ARM targets specialized for APE.

85aad9b397 Extend av_log2 in codeclib into a generic for scanning for set bits, which can provide either log2 or leading-zero-count output, and can force mapping 0 input to 0 output if needed (otherwise 0 input produces undefined result). Replace av_log2 in lib/codeclib.h, floor_log2 and wl_min_lzc in libfaad/common.c and common.h, and count_leading_zeros in libalac/alac.c with macros using bs_generic.

b9d7f98f8c Move av_log2 function and asociated table to the codec lib, remove 3 identical implementations, always have LUT in iram (gives a *tiny* speedup on coldfire), make the clz based function return the same value as the non clz based function for 0 input to be safe (slows down flac ~2% on the gigabeat S)

c6b3d38a15 New makefile solution: A single invocation of 'make' to build the entire tree. Fully controlled dependencies give faster and more correct recompiles. 
Many #include lines adjusted to conform to the new standards.

fe04e40be7 Further optimised (vs. libgcc) unsigned 32 bit division for ARMv4 (based on the ARMv5(+) version from libgcc), in IRAM on PP for better performance on PP5002, and put into the codeclib for possible reuse. APE -c1000 is now usable on both PP502x and PP5002 (~138% realtime, they're on par now). Gigabeat F/X should also see an APE speedup.

2f50cd58b9 Codec memory reorganization 
Based on a patch by Tomasz Malesinski
* Merge Codec buffer and Malloc buffer into one large buffer.
* The new merged buffer is now 1MB on targets with lots of memory.
* Renamed codec_get_memory to codec_get_buffer and made it behave more. 
like plugin_get_buffer.
* Bumped Codec api and min api versions.

46f85c4c54 Combine the Vorbis, WMA and AAC IMDCT functions and put them into the codeclib. Combined IMDCT is now based on existing Tremor transform. Reduces CPU for 192k AAC by 21MHz on Coldfire, and 5MHz on PP5024. WMA and Vorbis should have no functional changes since they already used this code. Further optimization is possible and would benefit all 3 codecs.

80da8b141c FS#6357, patch 1: let iramcopy and bss share the same space in codecs and 
plugins. Currently, in case of plugins using IRAM bss is cleared twice,
once in the loader, once in PLUGIN_IRAM_INIT. For codecs, bss is cleared only
during codec initialization. Also, removed double variables in codecs
storing a pointer to codec_api.

c91e0bbfc9 Cleaned up the messy codec header and library system by merging codec.h, lib/codeclib.[ch] and lib/xxx2wav.[ch] into just codeclib.[ch]. Deleted much of the unused code in the xxx2wav portion. All codecs should now only include codeclib.h, and whatever codec specific headers are needed.

Note that there is a small delay from leaving a setting until the change
can be heard (due to audio data buffering).
