Add the kthread handlers for video/vbi capture and video/vbi output.
These carefully control the rate at which frames are generated (video
capture) and accepted (video output). While the short-term jitter is
around the order of a jiffie, in the long term the rate matches the
configured framerate exactly.
The capture thread handler also takes care of the video looping and
of capture and overlay support. This is probably the most complex part
of this driver due to the many combinations of crop, compose and scaling
on the input and output, and the blending that has to be done if
overlay support is enabled as well.

There are several arch-specific media drivers that don't
require asm-specific includes and can be successfully
compiled on x86. Add COMPILE_TEST dependency for them, in
order to allow a broader test on those drivers.
That helps static analysis tools like Coverity to discover
eventual troubles there.
