Drop the the mdct files from libwmapro since they are no longer needed.

Fix red by removing sine_512 from iram (2KB). minor slowdown for PP5024 (~0.05MHz) on a 320kbps sample, and ~0.03MHz slowdown for Coldfire on a 55kbps sample.

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)

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.

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