MFC:
  Implement ifnet cloning for tun(4)/tap(4).
  Make devfs cloning a sysctl/tunable which defaults to on.

  If devfs cloning is enabled, only the super-user may create
  tun(4)/tap(4)/vmnet(4) instances. Devfs cloning is still enabled by
  default; it may be disabled from the loader or via sysctl with
  "net.link.tap.devfs_cloning" and "net.link.tun.devfs_cloning".

  Disabling its use affects potentially all tun(4)/tap(4) consumers
  including OpenSSH, OpenVPN and VMware.
