Pull up revisions 1.25-1.26 (via patch, requested by itojun):
  Mark cloned routes with RTF_CLONED.  Present it in ``netstat -r''
  output by ``c''.

  Let static routes overwrite cloned routes, as cloned routes can
  come back again if necessary.  Should fix PR#11916 and maybe some
  other PRs with ARP behavior.

  Cleanup cloned route when parent route (RTF_CLONING) goes away.
  Adds rt_parent to link parent from child (like NRL did, ours do
  refcnt rt_refcnt properly).
