Don't include <rump/rumpvnode_if.h> from rump.h. It's not needed
unless you're doing something special, but requires register_t.
Adjust the few places which actually need rumpvnode_if.h.

Clean up vnode lock operations pass 2:

VOP_UNLOCK(vp, flags) -> VOP_UNLOCK(vp): Remove the unneeded flags argument.

Add a simple tty server which attaches to /dev/ttyU in the rump
kernel and provides the same device on the host with pud(4). I
can succesfully talk to my u3g device using tip(1) against the
server's devices. Some characters are lost here and there, though
(probably a problem with interrupt pipes in ugenhc). Once that
issues is solved, there is no reason why e.g. pppd (chat) could
not be used against the server.

Now, why would anyone want to do this instead of using the kernel
driver directly? Well, for one, on my laptop I run netbsd-5 which
doesn't have a u3g driver which supports the u3g hardware I have.

As anyone with half an eye can see, this is quite copypasted from
umserv and there is plenty of opportunity for uncopypasting for
the eager vi-wielder.
