2016-05-03wmalossless: allow calling madd_int16Christophe Gisquet
This is done by actually handling the "prev_values" in the cascaded LMS data as if it were int16_t, thus requiring switching at various locations the computations.

2016-05-01avcodec/wmalosslessdec: silence a sample requestChristophe Gisquet
16bits samples with CDLMS orders of 8 are currently unsupported, but have never been encountered before. However, 8 seems to be the most frequent, if not the only order used for 24bits. In that case, the dsp functions are fine with handling order that are multiples of 8, so silence the warning. Signed-off-by: Paul B Mahol <onemda@gmail.com>

2014-06-06wma lossless: reuse scalarproduct_and_madd_int16Christophe Gisquet
This is done by padding the coefficient buffer with 0s, because the order may be only a multiple of 4, and the DSP function requires batches of 8. However, no sample with such a case was found, so request one if it uses that kind of order.
