Merge if.c:1.210, if_var.h:1.85 from HEAD to RELENG_5:

  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.
