Implement TUN[GS]IFHEAD ioctls. Passing a non-zero int to TUNSIFHEAD
tells that tun unit to prepend a four byte address family to packets
queued for tunread() and to expect a four byte address family at the
front of data received by tunwrite().
We queue any protocol received from the interface for tunread(), but
only accept INET, INET6, IPX and NETATALK from tunwrite(). There is
support for Xerox's NS stuff, but AFAICT config(8) doesn't ever
define NS.
