If you were to configure a v4 and v6 vrf pop and forward label
that both happened to be the same, unconfiguring one would
remove them both.
This fixes that issue by noticing if we should remove it or
not based upon v4 or v6 having the same label or not.

RFC 2328 (14.1) Premature aging of LSAs from
routing domain :
When ospf6d is going away (router going down),
send MAXAGEd self originated LSAs to all
neighbors in routing domain to trigger
Premature aging to remove from resepective LSDBs.
Neighbor Router Reboot:
Upon receiving Self-originate MAXAGEd LSA, simply
discard, Current copy could be non maxaged latest.
For neighbor advertised LSA's (current copy in LSDB)
is set to MAXAGE but received new LSA with Non-MAXAGE
(with current age), discard the current MAXAGE LSA,
Send latest copy of LSA to neighbors and update the
LSDB with new LSA.
When a neighbor transition to FULL, trigger AS-External
LSAs update from external LSDB to new neighbor.

Add the ability to pass in an afi to zebra. zebra_vrf keeps
track of the afi/label tuple and then does the right thing
before we call down. AF_MPLS does not care about v4 or v6
it just knows label and what device to use for lookup.

FRR/CL provides the means for injecting regular (IPv4) routes
from the BGP RIB into EVPN as type-5 routes.
This needs to be enhanced to allow selective injection.
This can be achieved by adding a route-map option
for the "advertise ipv4/ipv6 unicast" command.

Asymmetric routing is an ideal choice when all VLANs are cfged on all leafs.
It simplifies the routing configuration and
eliminates potential need for advertising subnet routes.
However, we need to reach the Internet or global destinations
or to do subnet-based routing between PODs or DCs.
This requires EVPN type-5 routes but those routes require L3 VNI configuration.
This task is to support EVPN type-5 routes for prefix-based routing in
conjunction with asymmetric routing within the POD/DC.
It is done by providing an option to use the L3 VNI only for prefix routes,
so that type-2 routes (host routes) will only use the L2 VNI.

When an l3-vni is enabled, type-2 routes are sent with 2 labels (l2vni and l3vni).
When it gets deleted, we need to update type-2 routes and send them with only one label (l2vni).

- ospfd/ospf_opaque.c: Update issue #1652 by introducing a new
function 'free_opaque_info_owner()' to clean list of callback owner
and call this function in appropriate place where 'listdelete_and_null'
is not used.
- ospfd/ospf_packet.c: In case of crash, ospfd is not been able to
flush LSA. In case of self Opaque LSA, when restarting, ospfd crash
during the resynchronisation process with its neighbor due to an
empty list of LSA to flood. Just add a control on the list count
in 'ospf_ls_upd_queue_send()' to escape the function and avoid the
problem.

Ensure that if multiple parameters for a VNI change simultaneously, the
changes are processed correctly. The changes of interest are the local
tunnel IP address and the tenant VRF to which this VNI is attached. The
former is used to originate type-3 routes as well as set the next hop of
all routes, the latter helps to determine the route targets and VNIs to
include in the route.

EVPN type-2 and type-5 routes received with a L3 VNI and corresponding RTs
are installed into the appropriate BGP RIB. Ensure that these routes are not
re-injected back into EVPN as type-5 routes when type-5 advertisement is
enabled; only regular IPv4 routes (and IPv6 routes in future) in the RIB
should be injected into EVPN.
As a benefit of this change, no longer restrict that EVPN type-5 routes
should be non-host routes - i.e., allow /32 IPv4 routes (and /128 IPv6
routes in future).
