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)

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%).

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.

Remove the floating point code from wmaprodec.c and change variable names accordingly.

Complete the conversion of WMA Pro to fixed point. Floating point code is still there for better history and to have a returning point in svn should something go wrong.

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
