GnuTLS is too strict on the SSL shutdown alert, and it's neither
mandatory in the spec or critical. As it's ignored in OpenSSL, we
should also suppress it in GnuTLS as well.

22afa87a8e kmsgrab: Fix DRM format definitions 
All DRM formats are defined in terms of little-endian words, so RGB formats
like XRGB actually have the elements in the opposite order order in memory
to the order they are in the name.

This does not affect YUYV and similar YUV 4:2:2 formats, which are in the
expected order.

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):
Results without the patch:
SSIM Y:0.956508 (13.615881) U:0.991601 (20.757750) V:0.993004 (21.551382) All:0.974405 (15.918463)
