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.

aacenc: Fix a segfault in search_for_quantizers
...
This reverts the removal of scoefs from AACEncContext.
It resulted in scoefs being a NULL pointer when
search_for_quantizers() is called.
