a943a132f3 aac: check the maximum number of channels
Broken bitstreams could report a larger than specified number of
channels and cause outbound writes.

d56668bd80 floatdsp: move scalarproduct_float from dsputil to avfloatdsp.

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.

f75f4194d1 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.

d53fe096e4 aacdec: Fix out of array writes (stack).
Set the element to channel vector (e2c_vec) size to be the maximum
number of aac channel elements. This makes it slightly larger than it
needs to be because CCEs are never mapped to output channel locations.

Also add a check that all input tags (legal or not) will fit.
