1bef4c6650 revert last commit (r24660). There was a mistake in the location of the 
shifts leading to a deteriorated sound quality for some samples.

f5a0d61a1b Further optimization and minor clean up of atrac codec: Unroll iqmf_dewindowing for non-ARM speeds up decoder by +10% on H300. Removed some non-used arrays. Codec is still not fully realtime on Coldfire targets.

8722c6f2bb Make deceodeSpectrum() store the spectral coefficients of odd bands in reverse order, rather than having to reverse them in IMLT(). Also saves 0.11MHz, ~0.16% speedup on PP5024.

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.

This is likely to impose a battery life hit on files which are unstreamable and not much smaller then the buffer, but should not impact streamable files at all.
