current route addition mechanism on shaprd support only ipv4/v6 nexthop
routes simply. so It doesn't need to ensure flags of zapi_routes.
Then when we want to configure more complicated routing feature (like a
srv6), we will want to control flags of zapi_route. In this patch, it
will supports to configure flags of zapi_route when sharpd calls
ZEBRA_ROUTE_ADD.

FRRouting operator can install seg6local route via ZAPI,
But linux kernel operator also can install seg6local route
via Netlink directry (i.e. iproute2)
This commit make zebra to parse non-frr seg6local
route configuration via netlink and audit Zebra's RIB.

With this patch, zclient can intall seg6local rotues whem
they set properties nh_seg6local_{action,ctx} on struct nexthop
and set ZEBRA_FLAG_SEG6LOCAL_ROUTE on zapi_route's flag.

This commit is a part of #5853 works that add new nexthop's addional
object for SRv6 routing about seg6local route. Before this commit,
we can add MPLS info as additional object on nexthop.
This commit make it add more support about seg6local routes.
seg6local routes are ones of the LWT routing mechanism,
so configuration of seg6local routes is performed by
ZEBRA_ROUTE_SEND, it's same as MPLS configuration.
Real configuration implementation isn't implemented at this commit.
later commit add that. This commit add only nexthop additional object
and some misc functions.

Ensure that if allocated route is not added to a table then it is
deleted to avoid leaking memory.
Add a new memory type for route table so that ospf6 routes can be
distinguished in the show memory output in isolation.

So far, "set tag" was 99% implemented in ospf6d, but registration of the
hook functions was missing, causing "set tag" actions in route maps to be
ignored in ospf6d.
This commit adds the missing hook registration.

When we get this sequence of events:
- zebra receives interface up, sends to ospf
- ospf receives intf up, processes( including neighbor formation and spf )
and sends route to zebra for installation.
- zebra receives route for processing, schedules it too happen in the future
- zebra receives interface down event, sends to ospf
- zebra processes route X and marks it inactive because nexthop
interface is down
- zebra receives interface up event, sends to ospf
- ospf receives both events and processes the change and decides
that nothing has changed so it does not send any route change for X to zebra.
At this point zebra has a route from ospf that is marked as inactive, while
ospf believes that the route should be installed properly.
Modify the code such that on an interface down event, ospf marks the routes
as changed if the ifindex is being used for a nexthop, so that when ospf
is deciding if routes have changed post spf that it can just automatically
send that route down again if it still exists.
