I've integrated it a bit better into the VirtualBox build system, added
the ports stuff and updated the patch for VirtualBox 4.0.2.

It is currently unclear to me why you add VIMAGE to CFLAGS but nowhere
check for VIMAGE in VBoxNetFlt-freebsd.c. Shouldn't we add a check for
VIMAGE in the #if defined line or is this already done somewhere deep in
the included headers?
