Log Message:
libva: put a temp bandaid on the giant mess I created (sorry)
a circular dependency of MesaLib - now libva will not depend on it,
this breaks stuff but unbreaks the tree ASAP

add a patch so va_trace.c should compile on freebsd, dragonflybsd, linux
and netbsd -- excluding it is a bad idea (undefined references, oops)

indirectly put openbsd as a broken platform for now

still fails at runtime with mpv.

bump PKGREVISION.
