8e0e4384b0 Revert "avfilter/vf_interlace : add AVX2 for lowpass_line 8 and 16"
This reverts commits 1a5865b6dc and
8fb1d63d91.

They made fate interlace tests fail when AVX2 was used.

a7f6bfdc18 avfilter/interlace: prevent over-sharpening with the complex low-pass filter
The complex vertical low-pass filter slightly over-sharpens the picture. This becomes visible when several transcodings are cascaded and the error potentises, e.g. some generations of HD->SD SD->HD.
To prevent this behaviour the destination pixel must not exceed the source pixel when the average of the pixels above and below is less than the source pixel. And the other way around.

Tested and approved in a visual transcoding cascade test by video professionals.
SSIM/PSNR test with the first generation of an HD->SD file as a reference against the 6th generation(3 x SD->HD HD->SD):
