floatdsp: move scalarproduct_float from dsputil to avfloatdsp.

This makes the aac decoder and all voice codecs independent of dsputil.

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.

Restructure av_log_missing_feature message
...
Some invocations include a verb in the log message, others do not. Yet
av_log_missing_feature expects callers to provide a verb. Change the
function to include a verb instead and update the callers accordingly.
The result is a more natural function API and correct English in the
function invocations.
