c537d5958e Commit FS#12069 - Playback rework - first stages. Gives as thorough as possible a treatment of codec management, track change and metadata logic as possible while maintaining fairly narrow focus and not rewriting everything all at once. Please see the rockbox-dev mail archive on 2011-04-25 (Playback engine rework) for a more thorough manifest of what was addressed. Plugins and codecs become incompatible.

85e40257dc Enforce that codecs wait for their metadata in a proper-ish and consistent manner. Sort of a halfway patch; best would be to give them an internal copy of the current track information which lasts unaltered by playback until a track switch or unload.

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)

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%).

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.

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.

d884af2b99 Partial conversion of the wmapro decoder to fixed point arithmetic. Currently inverse quantization & rescaling, 
imdct and windowing are all in fixed point.

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
