* ospf6_route.c: Add const qualifier to various char arrays of
constants. signed/unsigned fixes.
(ospf6_linkstate_table_show) argv is const
* ospf6_snmp.c: listnode typedef is dead.
(ospf6_snmp_init) Take struct thread_master arg, needed for
smux_init.
* ospf6_snmp.h: update ospf6_snmp_init declaration.
* ospf6d.c: (ospf6_init) add const qualifier to sargv, pass master
to ospf_snmp6_init.
* ospf6_asbr.c: const char update.
* ospf6_interface.c: ditto, plus signed/unsigned fixes.
(ipv6_ospf6_cost) Check whether cost fits in u_int32_t and use
strtoul.
* ospf6_intra.c: const char update. Parenthesise expression.
* ospf6_lsa.c: signed/unsigned and const char updates.
* ospf6_proto.c: ditto.
* ospf6_message.c: ditto.
* ospf6_lsdb.c: signed/unsigned update.
* ospf6_main.c: const char update.
* ospf6_neighbor.c: ditto.
