Description:
OSPF6 GR HELPER router should consider as TOPOCHANGE when
it receives lsas with max age and should exit from Helper.
But, it is not exiting from helper because this max age lsa is
considered as duplicated lsa since the sender uses same seq
number for max age lsa from the previous lsa update.
Currently, topo change is not considered for duplicated lsas.
So removed the duplicated check when validating TOPOCHNAGE.

When ospf6d originates an AS-external route that has been read from a kernel
routing table, then the metric of that route was ignored until now.
If a routemap is configured, then this metric will be redistributed from
now on.
Using metric increment and decrement in routemaps is supported by ospf6d now.

Pre-b74e965, we always merged nexthops of old (existing) and new (newly
generated, based on a LSA update) routes, making it impossible to remove
individual nexthops from a route. b74e965 replaced this by copying nexthops
from the new route to the old route. This works as long as the old and new
route are derived from the same LSA (e.g. multiple ECMP paths to the same
ABR). However, in case of multiple parallel ABRs, each of them originates a
LSA and the nexthops derived from them need to be combined to get the proper
route nexthops. So instead of trying to incrementally update the route
nexthops based on the old and new route nexthops, always recompute the route
nexthops by merging all of its path nexthops (which we're already updating
based on the LSA being processed).
Fixes#15777.

interface_up also handles changes to the interface type, i.e. broadcast
to ptp to ptmp. Connected routes for these are different and must be
readvertised, which is done in ospf6_interface_recalculate_cost() - but
only if the cost changed. Use the force variant here.

The code emitting connected routes was checking against the interface
state (which can also be lo/ptp/ptmp) rather than the interface type.
This was causing wrong IA prefixes for connected routes getting put up
out if the interface was down intermittently.

I noticed that ospf6d always had a linked list memory leak.
Tracking it down shows that frr_fini() shuts down the memory
system and prints out memory not cleaned up. eigrpd, mgmtd
and ospf6d all called cleanup functions after frr_fini leaving
memory leaked that was not really leaked.

Unfortunately, `ospf6d` is much worse than `ospfd` and `isisd` regarding
its state saving, due to the existence of the auth trailer code.
Again, this belongs in `/var/lib`, not `/var/run`.
Merge both state files into one, and add reconciliation code for the
auth seqno.
I'm gonna save my comment on the fact that `ospf6_auth_seqno_nvm_delete`
is not in fact used anywhere. Which is now a warning because it's
`static`. Well. It probably should be used somewhere, so leave it in.

clang-format doesn't understand FRR_DAEMON_INFO is a long macro where

(Also use only one `FRR_DAEMON_INFO(` in isisd so editors don't get

Replace `struct list *` with `DLIST(if_connected, ...)`.
NB: while converting this, I found multiple places using connected
prefixes assuming they were IPv4 without checking:
- vrrpd/vrrp.c: vrrp_socket()
- zebra/irdp_interface.c: irdp_get_prefix(), irdp_if_start(),
irdp_advert_off()
(these fixes are really hard to split off into separate commits as that
would require going back and reapplying the change but with the old list
handling)

https://www.rfc-editor.org/rfc/rfc5340.html#page-37 states:
If the interface type is point-

global scope IPv6 addresses associated with the interface (if any)
are copied into the intra-area-prefix-LSA with the PrefixOptions
LA-bit set, the PrefixLength set to 128, and the metric set to 0.

When redistributing a local route, ensure the forwarding address field
of AS-External LSAs is only set when the associated nexthop interface
is OSPF-enabled. This is necessary because the OSPF RFC requires that
the AS-External LSA forwarding address should be resolvable using an
intra-area or inter-area path.
