video: remove internal QP passing

This was required by vf_pp, which was just removed.

vf_dlopen has this stuff in its API. This API is considered stable, so
the related fields are not removed from it. But the fields are always 0
now, so there's no point in keeping the example program around.

vf_pullup.c did some extremely awkward passthrough of this information,
but didn't actually use it.
