Requires a new upstream function to test not for *import* support on a
given output pixel format, but also whether we can render to it.
Fixes: https://github.com/haasn/libplacebo/issues/173
That feature is overkill for a constant pointer to AVFilterLink which
can be stored in AVCodecContext.opaque (indirectly, because the link is
not allocated yet at the time the codec is opened).
This also avoids leaking non-NULL AVFrame.opaque to callers.
Add an optional filter_line3 to the available optimisations.
filter_line3 is equivalent to filter_line, memcpy, filter_line
filter_line shares quite a number of loads and some calculations in
common with its next iteration and testing shows that using aarch64
neon filter_line3s performance is 30% better than two filter_lines
and a memcpy.
Adds a test for vf_bwdif filter_line3 to checkasm
Rounds job start lines down to a multiple of 4. This means that if
filter_line3 exists then filter_line will not sometimes be called
once at the end of a slice depending on thread count. The final slice
may do up to 3 extra lines but filter_edge is faster than filter_line
so it is unlikely to create any noticable thread load variation.

The HDR metadata should be removed after HDR to SDR conversion,
otherwise the output frame still has HDR side data.

This makes the filter output match that of the C version.
It was left intentionally while we figured out if it was better
or not, and while it makes certain samples better, it makes static
samples jump around slightly.
