7464e98f74 aac: Simplify decode_mid_side_stereo 
Might spare few cycles if the compiler is naive and
makes the function more readable.

3aca10bf76 latm: Always reconfigure if no extradata was set previously 
AAC LOAS can have new audio config objects in the stream itself.

Make sure the decoder reconfigures itself when the first one arrives
midstream.

462d5e8e6c aacdec: set AVFrame sample_rate 
AVFrame.sample_rate is set in ff_get_buffer, but aacdec calls
ff_get_buffer before the samplerate is known. So it needs to be
set again before returning the frame.

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.
