Proposed patch
I took a stab at patching tun to bring it into parity with tap. In line with
tap behavior, it will check for the IFF_LINK0 flag on the interface. If
present, it will persist the IPs and routes even when the device node is
closed.
In addition to the use case listed in earlier comments, this makes IP-aliased
jail interaction with tun nicer in that processes within the jail (e.g.
OpenVPN) can be bounced without having to restart the jail or externally
reconfigure IPs/routes on the tun.
