When the same ip address is used on several interfaces,
and one of them gets deleted (or equivalent: set to down and
then address removed), rib_delete_ipv[46] will also remove
the connected route from other interfaces.
rib_delete_ipv[46] is called twice when an interface is
deleted:
- for the "ifdown" event
- for the address removal
(note: this may be specific to the netlink interface of linux)
The second call does not find the connected route to that same
ifindex anymore, but deletes similar connected routes to any
other ifindex instead.
Reason: the ifindex check is on the same level as the check
for ZEBRA_ROUTE_CONNECT/NEXTHOP_TYPE_IFINDEX. If everything
matches except for the ifindex, the "else" part (intended for
different route types) is executed, thus removing the route
from the wrong interface.
fix: move ifindex check inside the "then" part of the check
for ZEBRA_ROUTE_CONNECT/NEXTHOP_TYPE_IFINDEX. Now connected
routes to other ifindexes will not spill over to the "else"
part for different route types anymore.
* fix disagreement with C99 in zlog_debug calls
Format specifier in some zlog_debug calls for size_t values
was changed in order to C99 ('%u' -> '%zu').
* fix -Wsign-compare warnings
Type of return value of ospf6_packet_max() was changed.
* ospf6_route.c: (ospf6_route_best_next) Allows unlock route, even
when there's no next route. This is consistent with how
ospf6_route_next() behaves.
* ospf6_intra.c: (ospf6_intra_prefix_lsa_remove) Make sure the last
route considered is always unlocked. This is needed when the for
loop terminates because ospf6_route_is_prefix() returns zero.

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.

* ospf_abr_nssa_am_elected(): feed "best" instead of "address of best"
into IPV4_ADDR_CMP(), because "best" is a pointer; also, mean s_addr
field of the structures to get better typed pointers
IPV4_ADDR_SAME() wasn't passed the right union member, this could cause
a bug due to strict-aliasing. IPV6_ADDR_SAME() case got its fix before
the error could be created by macro upgrade.

ZEBRA_HELLO message is used by routing daemons to inform zebra
what type of routes daemon will be announcing to zebra. Also
zebra uses route_type_oaths array to track which daemon announces
which protocol. Zebra mops up routes if daemon didn't for some
reason.
The old algorithim looked up every node twice as it withdrew
the entry. It looks up entry once in redistribute_withdraw, then
looks it up again info_delete. Use result of first lookup
to do the free directly.
This may explain the slow performance observed in
https://bugzilla.vyatta.com/show_bug.cgi?id=4421
The delete_hook was being run after calling access list delete function.
This would cause ospf to dereference a NULL, in ospf_filter_update
because 'access->name' was already freed.

The new implementation makes use of a 64KB mapping table, which makes it
possible to compute masklen faster and with constant execution time. The
map also allows for additional version of the function, which can detect
errors in input argument.
The previous implementation had a variable cost of execution, which
depended on masklen in a non-linear manner, and at its worst (/31) was
4 times slower, than the new implementation. The only case of old
function just slightly outperforming the new one is /0, which is of
little practical interest.
All daemons modified to support custom path to zserv
socket.
lib: generalize a zclient connection
zclient_socket_connect added. zclient_socket and
zclient_socket_un were hidden under static expression.
"zclient_serv_path_set" modified.
Second patch replaces "VTY_GET_LONG ("AS", as_ul, arg);"
by "VTY_GET_INTEGER_RANGE ("AS", as, arg, 1, BGP_AS4_MAX);"
as done in all other code, which parses AS numbers.
ospf6_routemap_rule_match_interface* was imported from ospfd
daemon with minor changes. new CLI options defined.
`ospf6_routemap_rule_match_interface' was changed to support
IPv6 (ospfv3) route's external information.
AS_PATH is a well-known, transitive path attribute and cannot be flagged
as "Partial". This is what commit
77a20b8af32c926176f8492a086d9e4ec670496b implemented, but it did not
account, that bgp_attr_aspath() is also used to process AS4_PATH, which
is an optional, transitive path attribute and as such may be flagged as
"Partial". This change justfies the test condition.
