This commits attempts to fix a problem that occurs when mpls-te gets
removed from ospfd config. Mpls-te has an inter-as option, which can be
set to Off/Area/AS. Whenever the inter-as takes "Area" or "AS" as a
value, this value will not be cleaned after removing mpls-te or after
removing the ospf router. Therefore, if mpls-te is configured with
inter-as AS or Area and we remove mpls-te or the ospf router, the
inter-as will still preserve its value; therefore, next time mpls-te is
enabled, it will automatically inherits the previous inter-as value
(either Area or AS). This leads to wrong configuration, which can be a
problem for frr_reload.py.
The commits forces mpls-te to reset inter-as to Off before it mpls-te
gets removed from the configuration and before the ospf router gets
removed.

The `enum zclient_send_status` enum needs to be extended
throughout the code base to use the new states and
to fix up places where we tested against the return
value being non zero.

The route_map_object_t was being used to track what protocol we were
being called against. But each protocol was only ever calling itself.
So we had a variable that was only ever being passed in from route_map_apply
that had to be carried against and everyone was testing if that variable
was for their own stack.
Clean up this route_map_object_t from the entire system. We should
speed some stuff up. Yes I know not a bunch but this will add up.

Issue:
When the ospf area is changed from default to nssa or stub, the previously
advertised external LSAs are not removed from the neighbor.
The LSAs remain in database till maxage timeout.
Fix:
Advertise the external LSAs with age set to maxage and flood to the
nssa or stub area.

When Segment Routing is not enabled, some related output messages are
printed on the console especially when Segment Routing Debug is enabled.
This patch adds additional controls to check whether segment routing
is enabled or not.

Replace all lib/thread cancel macros, use thread_cancel()
everywhere. Only the THREAD_OFF macro and thread_cancel() api are
supported. Also adjust thread_cancel_async() to NULL caller's pointer (if
present).

Change thread_cancel to take a ** to an event, NULL-check
before dereferencing, and NULL the caller's pointer. Update

Create appropriate accessor functions for the rn->lock

ospfNbrStateChange is generated when the state of neighbor regresses or
it progresses to a terminal state. When transitioning to or from Full
state on non-broadcast multi-access and broadcast networks the trap
should be sent by the designated router. This last condition was not
taken into account when checking for the conditions of generating the
trap.

For TI-LFA, it is necessay to known the Adjacency SID advetise by the nieghbor
routers. However, the current Segment Routing code skip neighbor Adjacency SID
and thus, don't store them into the Segment Routing database.
This PR takes care of neighbor Adjacency SID by allowing to store them in the
Segment Routing database. Corresponding MPLS table entry is only configured if
the advertised Adjacency SID is global i.e. with L-Flag unset.
