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]
debug ospf6 lsa aggregation

Steps to reproduce the issue:
1. router ospf6
2. redistribute static
3. ipv6 route 1::1/128 Null0
4. no redistribute static
5. wait for Max aged LSA to flush
6. Check DB, crash occurs.
RCA:
Crash occurred while accessing listgetdata(listhead(ospf6->area_list))
When there is no area attached to any of the interface listhead(ospf6->area_list)
is NULL. Therefore it crashed due to NULL access.
Fix:
Check before accessing null pointer.

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:

Adding the "clear ipv6 ospf6 command" . It resets
the ospfv3 datastructures and clears the database
as well as route tables. It resets the neighborship
by restarting the interface state machine.
If the user wants to change the router-id, this
command updates the router-id to the latest static
router-id and starts the neighbor formation with
the new router-id.

For redistribute commands if route map is set, then route takes it's metric
values from the route map. But in the case that routemap is set but the
metric for the route map is not, then the route metric is set to type-1.
Check if the metric is set for the routemap. If not then set it as per
redistributed default values (type 2)

The default values will be set at the time of ospf6_redist_add

The ospf6_is_router_abr is checking to see if ospfv3 is an abr router
and also setting values. Let's rename it too `ospf6_check_and_set_router_abr`
to more accurately reflect what it is doing.
Additionally fix coverity #1505176 where we were not checking the return
value of ospf6_is_router_abr like we did every other time. In this
case we don't care about the return value so indicate that we do not.

If area is a normal area and has adjacencies up and then the user changes
the area to a stub area, the code was leaving existing AS-External LSAs in
the database and was sending AS-External LSAs into the stub area causing
the adjacency to stay in Ex-Start. With this change we now cleanup the
AS-External LSAs that existed when area was not a stub and do not advertise
AS-External LSAs into the stub area.
