From various tests, there is no evidence that the filter is faster than
the native tinterlace, and it has several more limitations and a few
bugs.

Same funcionality is provided by stereo3d=ab[2]{l,r}:sbs[2]{l,r}.
Additional "features" are barely useful and cause crash or artifacts.

The next commit will introduce a proper decimation filter to be used
along with the field matching filter. To avoid confusion with this
filter which has currently a very limited usage (and will not work
properly with the fieldmatching filter), the new decimation filter will
take the decimate name, and this filter is renamed to mpdecimate.

This removes the ability to put AVFilters in read only memory and having
them shareable.

lavfi: add avfilter_init_str() to replace avfilter_init_filter().
avfilter_graph_create_filter() opaque is still passed to avfilter_init_filter()
which continues to pass it to init_opaque as its still used in the buffer sinks
the sinks should be changed and the opaque passing removed

This also drops support for "flat syntax" and "reinit" command.
"reinit" command is not very robust and complicates the logic more than
necessary, since requires to reset all the options in the command.
*This is a syntax break*.
Since we do not support "standalone" filters not attached to an
AVFilterGraph, we should not have a public function to create such
filters. In addition that function is horribly named, the action it does
cannot be possibly described as "opening" a filter.

This expression is useful to enable/disable overlaying on the fly.
Note that this can't be easily done relying on the filtergraph structure,
since this implies caching issues or a null frame overlaying in the best
case, which is better avoided for performance and convenience reasons.
Add support for dynamic x, y expressions evaluation.
Also add support for an evaluation mode which allows to disable per-frame
evaluation, so that there is no speedloss in case the expression does not
depend on frame variables.
Except for the vintage preset, the values are defined by Lou Logan based
on the ones found in Adobe Photoshop CS6.
