Makes it possible to use deinterlacers which output one frame for each field as fallback if field
matching fails (combmatch=full).
Currently, the documented example with fallback on a post-deinterlacer will only work in case the
deinterlacer outputs one frame per first field (as yadif=mode=0). The reason for that is that
fieldmatch will attempt to match the second field regardless of whether it recognizes the end
result is still interlaced. This produces garbled output with for example mixed telecined 24fps and
60i content combined with a field-based deinterlaced such as yadif=mode=1.
This patch orders fieldmatch to revert to using the second field of the current frame in case the
end result is still interlaced and a post-deinterlacer is assumed to be used.

The frei0r API requires linesize to be width * 4.
Since the align property of ff_default_get_video_buffer2
specifies line alignment, not buffer alignment, the
previous value of 16 breaks this requirement for frames
whose width is a multiple of 8, but not a multiple of 16
as it adds extra padding to ensure line aligment.
Fix Trac ticket #9873
summary: This patch modifies the `curves` filter with new `interp` option
to let user pick the existing natural cubic spline interpolation
and the new PCHIP interapolation.
reason: The natural cubic spline does not impose monotonicity between
the keypoints. As such, the fitted curve may vary wildly against
user's intension. The PCHIP interpolation is not as smooth as
the natural spline but guarantees the monotonicity. Providing
both options enhances users experience (e.g., reduces the number
of keypoints to realize the desired curve). See the related bug
report for the example of an ill-interpolated curve.
alternate solution:
Both Photoshop and GIMP appear to use monotonic interpolation in
their curve tools, which were the models for this filter. As
such, an alternate solution is to drop the natural spline and
go without the `interp` option.

Doxygen does not properly form references that span multiple levels,
so instead reword it a bit and manually add the references to what
they should point to.
This filter currently keeps the input timebase, but produces CFR output.
It is thus simpler to use 1/output fps as the output timebase.
Also, set output frame durations.
Fixes the following integer overflows:

libavfilter/vf_rotate.c:273:50: runtime error: signed integer overflow: 65286 * 38044 cannot be represented in type 'int'
Fixes ticket #9799, different output with different compilers.
Apparently this option was intended (the context contains a
currently-unused frame_rate field), but was never added. This results in
the output timebase being unset after config_output(), so the input
audio timebase ends up being used for video output, which is clearly
wrong.
Add an option for setting output video framerate. Also set output frame
durations.
When force_original_aspect_ratio and force_divisible_by are both
used, dimensions are now rounded to the nearest allowed multiple of
force_divisible_by rather than first rounding to the nearest integer and
then rounding in a static direction. This results in less distortion of
the aspect ratio.
