RFC 5187 specifies the Graceful Restart enhancement to the OSPFv3
routing protocol. This commit implements support for the GR
restarting mode.
Here's a quick summary of how the GR restarting mode works:
* GR can be enabled on a per-instance basis using the `graceful-restart
[grace-period (1-1800)]` command;
* To perform a graceful shutdown, the `graceful-restart prepare ipv6
ospf` EXEC-level command needs to be issued before restarting the
ospf6d daemon (there's no specific requirement on how the daemon
should be restarted);
* `graceful-restart prepare ospf` will initiate the graceful restart
for all GR-enabled instances by taking the following actions:
o Flooding Grace-LSAs over all interfaces
o Freezing the OSPF routes in the RIB
o Saving the end of the grace period in non-volatile memory (a JSON
file stored in `$frr_statedir`)
* Once ospf6d is started again, it will follow the procedures
described in RFC 3623 until it detects it's time to exit the graceful
restart (either successfully or unsuccessfully).
Testing done:
* New topotest featuring a multi-area OSPF topology (including stub
and NSSA areas);
* Successful interop tests against IOS-XR routers acting as helpers.

Feature Implementation.
========================
This feature will help in advertising the External LSAs with aggregation.
The commands allow us to tune the advertisement with different parameters
as mentioned in the CLI List below.
It can also help in case we do not want to advertise any prefix with the
no-advertise option.
New CLIs added:
===============
summary-address X:X::X:X/M$prefix [tag (1-4294967295)] [{metric (0-16777215) | metric-type (1-2)}]
no summary-address X:X::X:X/M$prefix [tag (1-4294967295)] [{metric (0-16777215) | metric-type (1-2)}]
summary-address X:X::X:X/M$prefix no-advertise
no summary-address X:X::X:X/M$prefix no-advertise
aggregation timer (5-1800)
no aggregation timer (5-1800)
show ipv6 ospf6 summary-address [detail$detail] [json]

Problem Statement:
==================
when route-map config is changed from permit to deny, it is not getting
applied to both connected and static and vice versa
RCA:
==================
When route-map changes from permit to deny or vice versa, a notification is
sent to ospf6 daemon via ospf6_asbr_routemap_update. In this function, a thread
is scheduled after 5 seconds to apply the route-map changes. In this thread
(ospf6_asbr_routemap_update_timer), only the first type is passed as argument
and only the first type i.e "connected" is passed and hence in callback only
on this type of route route-map gets applied.
Fix:
====
Need to loop through all the route-types in the call back and process
the route-map changes. Added a flag to mark which all route-types needs
to be processed.
Test Executed:
===============
1. Change route-map from permit to deny.
2. Change route-map from deny to permit.
3. Add new route and checked.
4. Verified summarised routes.
Risk:
============

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.
