1b20853fb3 avfilter/internal: Factor out executing a filter's execute_func 
The current way of doing it involves writing the ctx parameter twice.

18ec426a86 avfilter/formats: Factor common function combinations out 
Several combinations of functions happen quite often in query_format
functions; e.g. ff_set_common_formats(ctx, ff_make_format_list(sample_fmts))
is very common. This commit therefore adds functions that are equivalent
to commonly used function combinations in order to reduce code
duplication.

7f6d20931b avfilter/vf_v360: fix visibility test for fisheye projection 
Previously the visibility test referred to a circle in the input. This
changes it so that it refers accurately to the entire area in the input.

1050f94c22 avfilter/vf_v360: allow user to control fov for equirectagular format 
It may be useful to use different values from typical 360/180 deg.

ce8f45aaba avfilter/vf_v360: fix several problems with 'perspective' output 
The image center wasn't preserved, the output image was mirror reversed,
and rotations were made around wrong axes.
I did also remove the vector normalization, because it's sure that the vector
is already normalized if it's calculated from sin() and cos() terms.

d813e43b3d avfilter/vf_v360: adjustment out_pad and in_pad maximum value to 1/10 
Because not every user know about in_pad and out_pad reasonable value range
so maybe try to set 1.0, but setting 1.0 is so hugh to get an fatal error.
