Log Message:
Per discussion on tech-net@, discard the address-munging hack that
let one create a tunnel with equal inner and outer destination IP
numbers.  Update gre(4) documentation for this change.

Extract subroutine  gre_update_route() from gre_compute_route(),
and always call it in gre_output() to freshen the route for
tunnel-encapsulated packets.
