4b49ef2ade Another minor ARM speedup for libwmapro. Drop lsb of multiplication result in fixmul31(). The difference to current implementation is +/-1 in the output signal. Same routines are used for other codecs and in the codec lib as well.

cc7fac27b5 Minor of libwmapro on ARM. Swap operands for fixmul31, is 1% faster.

13167d2389 Remove the comment about Coldfire asm. The current code (using fixmul16 macros) is fast enough; even faster than an equivalent CF asm version, as pointed out by Nils Wallménius.

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%).

30d286d859 libwmapro: slightly shorter and faster inline asm fixed point multiplication routines, speedup is ~0.5%. Also don't lie to gcc about which vars are changed by the asm.

imdct and windowing are all in fixed point.
