4674518787 Increase wmapro decoder output sample depth to 24 bits, makes the mean error between our output and the original floating point decoder ~5e-8. (FS#11498 by Buschel)

3bbbb96395 Use codeclib's mdct in wmapro. Input coeffs to the transform needed to be scaled down first by (log2(frame_size) - 3). Increases decoding speed by 1.3MHz on PP5022 and saves ~32KB that were previously needed by the mdct tables. (FS#11511 by Buschel and myself)

aa2fca384a 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%).

2fefcdf31c Refinement of initial lowmem handling for libwmapro (r27593). Set maximum supported channels to 2 instead of 8 for low memory targets. This solution saves more RAM than the former solution and does avoid possible NULLPTR access. As add-on remove tabs.

5dd8c53b96 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) 
on mcf2049.

87d59ab56c Submit part of FS#11498. Major speedup for WMA Professional on ARM and Coldfire CPUs. Introduce asm routines for multiplications, move arrays with major impact on decoding speed to IRAM. Speeds up decoding by 25% on PP5022 and 34% on mcf5249.

d63abfc7eb 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.

816fca820c 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
