Maintenance and minor speedup of libwmapro. Comment unused arrays, fix comment, remove tabs and introduce WMAPRO_FRACT to wma.h to remove magic numbers. Swap operands of fixmul16-call for minor speedup on ARM (+1%).

Modify the wma pro decoder to produce non-interleaved samples, and work directly on the buffers in WMAProDecCtx instead to avoid the redundant copying of the output data. ~10% speedup (-2MHz) on pp502x and ~1.5% speedup (-3.8Mhz)

Add WMA Pro to the main build. WMA Pro now plays on target and decodes in 151% realtime in a 320kbps sample on a sansa e200. Lots of cleanup still need to be done, and optimisations should start soon too.

Partial conversion of the wmapro decoder to fixed point arithmetic. Currently inverse quantization & rescaling,
...
imdct and windowing are all in fixed point.

Wrote apps/codecs/wmapro.c and modified libwmapro to make the codec work in the sim. Neither libwmapro nor wmapro.c have been added to the main build yet, codecs.make should be edited to compile both with rockbox.
...
current status of the decoder :
- Plays and seeks in the sim
- Still in floating point
