This is a port of the kerndeint filter (libmpcodecs/vf_kerndeint) by
Donal A. Graft (original avisynth plugin author), and is based on the
work by Jérémy Tran <tran.jeremy.av@gmail.com> done for SOCIS 2012.

Force commands to specify the name of the test to run. This simplifies
extending the function with a new parameter, which will be done in a
following patch.

After making some blind tests on a small collection of music
samples for home usage. It turned out that the default cutoff
was too low.

The impact of filter_size was not clearly distinguishable (the
results were on the edge) with the music samples but turned out
to be clearly audible in some synthetic samples.

Thanks to Daniel for helping out with the listening tests.

Also rename the "enable_auto" field to "deint", to match the name of the
option.

This is better than repeatedly failing during the filtering stage.

The misspelling is used in the specification.
