vf_vdpaupp: use refqueue helper

This makes vf_vdpaupp use the deinterlacer helper code already used by
vf_vavpp. I nice side-effect is that this also removes some traces of
code originating from vo_vdpau.c, so we can switch it to LGPL.

Extend the refqueue helper with a deint setting. If not set,
mp_refqueue_should_deint() always returns false, which slightly
simplifies vf_vdpaupp. It's of no consequence to vf_vavpp (other than it
has to set it to get expected behavior).
