4c0080b7e7 wmaprodec: return an error, not 0, when the input is too small. 
Returning 0 may result in an infinite loop in valid calling programs. A
decoder should never return 0 without producing any output.

42d3246948 floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp. 
Now, nellymoserenc and aacenc no longer depends on dsputil. Independent
of this patch, wmaprodec also does not depend on dsputil, so I removed
it from there also.

b4027d9749 wmapro: change max. block size to 13 bits. 
WMApro actually support 13-bits block sizes (potentially even up to 14),
and thus we should support that also. If we get block sizes beyond what
the decoder can handle (14 is possible depending on s->decode_flags),
error out instead of crashing.
