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

Major optimization of atrac3 codec for Coldfire targets. Moving several number cruncher arrays to IRAM. Decoder is sped up by +50% on h300, decoder now finally is realtime on Coldfire targets as well.

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.

Revert r22339 as it causes immediate stack overflow on target, at least on coldfire.

Make the IMDCT temporary working buffer a local variable instead of keeping one for each channel. Saves 4KB of RAM.
