This patchsets implements the feature requested on ticket #4347.
The first three patches are preparation work. The first one isn't
strictly related to the implementation, but comes in handy
nonetheless.
Patches 4 to 11 can be squashed into a single commit before pushing
if that's prefered, but for
Printing the dynamic buffer offset is useless.

Please fix the UB in the MMX-code.

Hello,
This patch is done for performance increase on UHD or above resolution
color space convertions.
Some SDI sources provide yuv422p10 for 10bit source and uyvy422 for 8 bit
source.
To encode these sources with NVENC 10 bits, there is a need to convert
these color spaces to P010.

Is this true or is it just working by accident?

Still, using floats in malloc() looks like a very bad idea, borderline
recipe for disaster. Especially on x86_32.
