Details

This is a patch that modifies wma codec to produce non-interleaved output. I don't have any target to measure the speedup now, so I'd be grateful if someone could do that for CF and ARM. (I can test for ARM but in a couple of days).

The decoder uses a scratch buffer for mdct, windowing and overlapping, if this could be modified so that the scratch buffer isn't needed, it would save ~8K of memory too.
This task depends upon

Fixed a mistake in the buffers passed to pcmbuf_insert. Pointer confusion !
