Commit FS#11709 by me. Introduces ARMv5E optimized iQMF for atrac3 based on packed multiply instructions. Additionally, improves scheduling on arm9 and arm11 and forces cache alignment of buffers on all targets. Accuracy is slightly reduced, but still greater then 16 bit. Clip+ CPU clock required for LP2 files decreases by 13MHz and ARM11 by 18MHz. No performance or accuracy changes on armv4 or non-arm.

Make atrac3 streams in wav containers work again (error was introduced with r24782). Add additional info to atrac3 debug information.

"Detach" ATRAC3 from RM. Since ATRAC3 isn't really specific to RM, it must not be obligatory to initialize the decoder through RMContext.

Smarter check for failed packet parsing in RM. Also fixes a bug in playback where sometimes "codec failure" is splashed at the end of playback.

Further performance optimization of the atrac3 decoder. Rework the internal sample representation and usage of dsp routines. For now a quick and dirty solution is used to add a fract part of 2 bits. Through this several buffers and functions as well as copy loops could be removed. Furthermore add some ASM for coldfire and place some additional data in IRAM on PP5022/24 and X5/M5. Speedup on ARM: +3%, speedup on Coldfire: +639%. Both ARM and Coldfire can decode in realtime now.
