the libavfilter/vf_blackframe.c filter now not only logs detected
values, but also sets frame metadata. Currently, only `pblack` value is set
but `SET_META` macro has been introduced to ease development in the future.

And use the x86util ones instead, which are optimized for mmxext/sse2.
About ~1% increase in performance on pre SSSE3 processors.

af_compand: make sure request_frame always outputs at least one frame
See: 6b68e2a43b3407522080be50a2a19cff2f9715ef

This fixes a segmentation fault because request_frame in fifo.c assumes
that the call to ff_request_frame will populate fifo->root.next.
Before, it was possible for request_frame in af_compand to not do this,
resulting in a null pointer access. Now, request_frame in af_compand
always will return at least one frame or an error, as per the API
specifications in avfilter.h for request_frame.

This is especially useful to debug queue overflow issues.
Ideally we should be able to set the debug message at the
dualinput/framesync level, but they do not have the information related
to the filter context and the inlink, so cannot access much useful
information.

The gcc version affected is very old and unmaintained AFAIK thus i made no
attempt to report this to the gcc developers.
The workaround is pushed as it may still affect users and does affect one
fate client

This makes C and MMX match, no change to fate as the differences where
apparently not sufficient to show up in fate

This surely can be optimized more, i just didnt want to cause a slowdown
when trying to make the fate test bitexact.
Further optimization left to ubitux
