Pass down the safi for when we need address
resolution. At this point in time we are
hard coding the safi to SAFI_UNICAST.
Future commits will take advantage of this.

PIM is going to need to be able to send down the address it is
trying to resolve in the multicast rib. We need a way to signal
this to the end developer. Start the conversion by adding the
ability to have a safi. But only allow SAFI_UNICAST at the moment.

The entirety of the import checking no longer needs to be
in zebra as that no-one is calling it. Remove the code.

These are no longer really needed. The client just needs
to call nexthop resolution instead.
So let's remove the zapi types.

OSPFv3 recently introduced the usage of import route. Switch it
back to using the normal ZEBRA_NEXTHOP_REGISTER command.

Allow bgp to figure out if it cares about address resolution instead
of having zebra care about it. This will allow the removal of the
zapi type for import checking and just use nexthop resolution.
Effectively we just look up the route being returned and
if it is in either table we just handle it instead of
looking for clues from the zapi message type.

This `XFREE()` call is in plainly in the wrong spot. `rp_all` (the
224.0.0.0/4 entry) isn't supposed to be free'd ever, and the
conditional above makes quite clear that it remains in use.
It may be possible to exploit this as a heap corruption bug, maybe even
as RCE. I haven't tried; I randomly noticed this while working on the
BSM code. Luckily this code is only run by the CLI for the clear
command, so the surface is very small.

The paf data structure is stored based upon an internal
bgp enum. The code is looking over all AFI/SAFI's and
doing a paf_af_find which then calls afindex to find
the right paf structure. Let's just loop over the
peer->peer_af_array[] and cut straight to the chase.
Under some loads the paf_af_find was taking up 6%
of the run time. This removes it entirely.

The ospf6 router-id is provided by order of preference by:
ospf6d itself if the "ospf6 router-id X.X.X.X" command is set.
- zebra. If the "ip router-id X.X.X.X" zebra command is set, the
configured IP is provided as the ID or alternatively the highest
loopback IPv4 address or else the highest interface IPv4 address.
The running ospf6 router-id is stored in ospf6->router-id.
ospf6->router-id can change in the following conditions:
- A configuration change provides a new router-id value according to
the above rules. ospf6->router-id is updated to the new value if
there is no adjacency in FULL state. Otherwise, the ospf6d process
must be restarted to take the new router-id into account.
- On startup of both zebra and ospf6d, if ospf6d has not yet received a
valid router-id, ospf6d->router-id is set to 0 (i.e. 0.0.0.0). Then,
zebra notifies ospf6d that the router-id is available.
At ospf6->router-id, the current behavior of ospf6d is the following:
- The self generated LSAs that refer to the previous router-id as the
advertising router are kept.
- Self generated LSAs are created with router-id value.
- LSAs from the redistribution that refer to the previous router-id are
kept and no new redistribution LSAs are created.
As a consequence, the routers in the ospf6 areas will get incorrect
LSAs and might not be able to install prefixes of those LSAs into their
RIB.
This fix solves this issue by resetting the areas and the redistribution
when ospf6->router-id updated.

The typesafe containers have been around for quite a while now and
haven't gone up in a blaze of flames, so let's add a "strong
recommendation" to use them for new code and refactors.
For the nhrpd custom lists I'm already working to remove them; meanwhile
the old skiplists are primarily used in RFAPI (4 users outside of that),
so those could be next.
What remains are the old `list_*` and `hash_*`, which have >300 and >100
users respectively, making them a much harder problem to tackle. And
the new hash implementation doesn't have the same level of
debug/introspection yet (it's on my TODO.)
