Modified Files:
        src/sys/miscfs/nullfs: null_vnops.c
        src/sys/miscfs/umapfs: umap_vnops.c
        src/sys/miscfs/union: union_vnops.c
Log Message:
We must handle MNT_NODEV at open time, so add an open op for null and union,
and do proper checks in union_open(). Fix to nullfs from OpenBSD, extended
to umap and union by me.
