ospf6d: Have ospf6d cleanup when it terminates normally
A clean exit makes it easier to use memory debuggers.
* ospf6_asbr.c: (ospf6_asbr_terminate) Add a function to do route map
cleanup.
* ospf6_lsa.c: (ospf6_lsa_terminate) Add a function to cleanup the lsa
handler vector.
* ospf6_main.c: (ospf6_exit) Add an function that causes ospf6d to
gracefully exit.
* ospf6_message.c: (ospf6_message_terminate) Add a function that frees
the send and receive buffers.
* ospf6_top.c: (ospf6_delete) Enable the ospf6_delete() function.
Disable ospf6 before freeing everything.
