The other BSDs use dev_t in both kernel and userland to mean the same
thing, which is equivalent to how we use udev_t.  Fixing this has a lot
of benefits and I'm totally in favor of it.  I share Warner's concern
about 4.x/5.x compatibility, but I gave up on that in my drivers long
ago since the API have changed to much.
