deinterlace: Better alternate support
...
Improve line offset halving based on whether this field is top or
bottom.
Also handle the buffer state the same as mixed.

deinterlace: Call the planar functions for the Y plane of nv12/nv21
...
In some algorithms (like yadif), the Y plane has to be handled different
than the UV plane. Therefore, the planar_y functions are now called for
the Y plane, and the nv12/nv21 functions are handling only the UV/VU
planes respectively.

deinterlace: Allow for 5 fields for interpolation
...
Add an extra field to the simple deinterlace implementation,
so that methods can potentially use 5 fields - the current
field, and 2 before and 2 after.

deinterlace: add alternate support
...
In this mode each field is carried using its own buffer.
Allow deinterlace to negotiate caps with the Interlaced feature and
adjust the algorithm fetching lines.

deinterlace: stop checking line index boundaries

The LINE2() macro already prevents out of bound indexes using CLAMP_HI()
and CLAMP_LOW().

deinterlace: change field handling through methods
...
This likely breaks stuff. The good: all of the methods now create
field images aligned with input frames, without timestamp mangling.
The bad: this touches a lot of code, much of which is hairy and in
need of cleanup. However, at this point we can reasonably create a
PSNR-based test.

deinterlace: rewrite how neighboring scan lines are calculated
...
Old code was difficult to understand exactly how the neighboring
scan lines are calculated, and it appeared that some were off by
+2 or -2, depending on the field flag. Fixes #639321 .
