* ospf_lsdb.c: (ospf_lsdb_delete_entry) new function, consolidate
exact same functionality replicated in other functions.
(ospf_lsdb_add) Strip out code by using ospf_lsdb_delete_entry.
(ospf_lsdb_delete) ditto.
(ospf_lsdb_delete_all) ditto.

* ospf_lsa.{c,h}: (ospf_lsa_unlock) Change to take a double pointer
to the LSA to be 'unlocked', so that, if the LSA is freed, the
callers pointer to the LSA can be NULLed out, allowing any further
use of that pointer to provoke a crash sooner rather than later.
* ospf_*.c: (general) Adjust callers of ospf_lsa_unlock to match
previous. Try annotate 'locking' somewhat to show which 'locks'
are protecting what LSA reference, if not obvious.
* ospf_opaque.c: (ospf_opaque_lsa_install) Trivial: remove useless
goto, replace with return.
* ospf_packet.c: (ospf_make_ls_ack) Trivial: merge two list loops,
the dual-loop predated the delete-safe list-loop macro.

* ospf_lsdb.c: (ospf_lsdb_delete) robustify against NULL arguments,
print warning.
* ospf_lsa.c: (ospf_discard_from_db) ditto.
(ospf_maxage_lsa_remover) Check lsa->lsdb for validity, possible
mitigation (but not solution) for bug #269.

* (general) extern and static qualifiers added.
unspecified arguments in definitions fixed, typically they should
be 'void'.
function casts added for callbacks.
Guards added to headers which lacked them.
Proper headers included rather than relying on incomplete
definitions.
gcc noreturn function attribute where appropriate.
* ospf_opaque.c: remove the private definition of ospf_lsa's
ospf_lsa_refresh_delay.
* ospf_lsa.h: export ospf_lsa_refresh_delay
* ospf_packet.c: (ospf_make_md5_digest) make *auth_key const,
correct thing to do - removes need for the casts later.
* ospf_vty.c: Use vty.h's VTY_GET_INTEGER rather than ospf_vty's
home-brewed versions, shuts up several warnings.
* ospf_vty.h: remove VTY_GET_UINT32. VTY_GET_IPV4_ADDRESS and
VTY_GET_IPV4_PREFIX moved to lib/vty.h.
* ospf_zebra.c: (ospf_distribute_list_update_timer) hacky
overloading of the THREAD_ARG pointer should at least use
uintptr_t.

* ospf_lsdb.h: Export ospf_lsdb_clean_stat() function.
* ospf_spf.h: Add link to the LSA stat structure into vertex.
* ospf_spf.c: New functions cmp() and update_stat() to manage
candidates. Remove ospf_spf_has_vertex(), ospf_vertex_lookup(),
ospf_install_candidate() and ospf_spf_register() functions not needed
any more. Update ospf_vertex_new(), ospf_spf_next() and
ospf_spf_calculate() functions to use pqueue instead of linked list.
