9f6586698a APE codec: Speed up decoding of -c2000 and higher on ARMv4 and coldfire by fusing vector math for the filters. Speedup is roughly 3.5% for -c2000, 8% for -c3000 and 12% for -c4000. To be extended to other architectures.

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.

2347a7dc65 Small fix for ARMv5e/v6 APE divider, correct large-divisor path and remove specialized version of it for small dividend, as the test and branch can't be fit into delay slots on that path.

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.

c1f4d4037a More comments for udiv32_armv4.S, reduce zero divisor test to one cycle for the skipped branch by setting flags when inverting divisor, 32-bit numerators are handled by calling the 31-bit divider and fixing the results.

822abc1236 Add 31/31-bit unsigned division in apps/codecs/lib/udiv_arm.S, with 2 cycles / iteration, falling back to previous 32-bit, 3 cycle / iteration code when needed (well under 1% of divisions in sample file). APE normal sample is now 96.90% realtime, approx 1.3% improved vs svn. TODO: unify divisor normalization for both trial subtraction routines, possibly use divisor bits to select 31- vs 32-bit division.

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)
