Subject: [PATCH] Add support for OpenBSD

With OpenBSD there is one major problem: no support for proper file
sharing (neither virtualbox sharing nor NFS). The only option left is
using the rsync mechanism, which has two glitches:

 * It requires an explicit `vagrant rsync` to update code in a running
   guest, as the sync mechanism is otherwise only triggered on
   `vagrant up` and `vagrant reload`.
 * The rsync mechanism is one way from host to guest. For getting files
   out of the guest some other mechanism must be used (there is a
   plugin `rsync-back` that worked for me).
