  Log:
  Merge if.c:1.210, if_var.h:1.85 from HEAD to RELENG_5_3:
  
    Define IFF_LOCKGIANT() and IFF_UNLOCKGIANT() macros, which conditionally
    acquire Giant if the passed interface has IFF_NEEDSGIANT set on it.
    Modify calls into (ifp)->if_ioctl() in if.c to use these macros in order
    to ensure that Giant is held.
