  Log:
  - Factor out if_purgeaddrs_nolink(), which frees all non-link ifaddrs no
    ifnet.if_addrhead
  - Use above function in if_detach() and free link ifaddr manually, add some
    assertion there to make sure ifnet.if_addrhead is in sane state
  
  Submitted-by: pavalos@

  For tap(4)
  - Use if_purgeaddrs_nolink() to clean up tap's if_addrhead
  - Cleaning up ifaddrs has nothing to do with current tap's mode (vmnet/tap)
  - In non-vmnet mode, clear IFF_RUNNING if_flags when a tap is brought down
  
  For tun(4)
  - Use if_purgeaddrs_nolink() to clean up tun's if_addrhead
  - Cleaning up ifaddrs has nothing to do with IFF_RUNNING
  - in_control() is clever enough to set the RTF_HOST flags for tun, so tun
    does not need to record that dst addr has been set.  Since net/tun/if_tunvar.h
    was exposed to /usr/include "accidentally", instead of nuking TUN_DSTADDR,
    I just mark it as "unused" in comment.
