RCA: When upstream transition from Joined to NotJoined due to SGRpt
prune, then only SGRpt prune was sent and SG Prune is missed.
Fix: Send SG Prune towards source as well as SGRpt prune towards RP.

The interface area command is deprecated under
router ospf6 and should be on the individual interface.
Let's modify the tests to not actually put the
interface foo area 0.0.0.0 command under the
router node.

When using build_config_from_json there exists a timing
window where neighbors can come up before the router-id
is applied. As a precaution, quickly clear the neighbors
to ensure that we get neighbors with the expected router-id.
This can especially happen under high system load.

When testers use the build_config_from_json function
the create_router_ospf function is double creating
the ospfv3 cli to be passed in. This is because
the create_router_ospf loops over both v2 and v3
and then create_router_ospf6 re-adds v3.

The ospf_basic_functionality/test_ospf_lan.py creates
a ethernet segment and attaches 4 routers to it and
assigns ip addresses in a /24. As one of the tests
it picks a new address for r0 which coincides with
a ip address on r3. Then the test immediatly
checks for other data. The problem is of course
that if a test is `slow` enough hello's will
start to be ignored from r3 to r0 and the
neighbor relationships will come down. Choose
an ip address that doesn't cause this issue.

The new bgp_route_server_client test is not setting the
timers for peers to be fast enough to have the ability
to converge in under 60 seconds if a packet is dropped/missed
at startup. Make the test have the ability to converge

The external_id_table was only ever used to store pointers to data
and was never used for lookup during the course of normal operations.
However it did lead to crashes because somewhere along the way
external routes stored in the external_table never had their
id associated into the external_id_table and we would assert
on the node lookup failing.
Since this code was never used for anything other than
storing data and it was never retrieved for anything useful
let's just remove it from ospf6d.

When the VRF interface is coming up, we don't need to fixup VRF ids - it
was already done in static_vrf_enable when the interface was created.

For IPv4 matching, we have "match ip next-hop address A.B.C.D".
For IPv6 matching, we have "match ipv6 next-hop X:X::X:X".
To have consistency, let's add "address" keyword to IPv6 commands.
Old commands are preserved as hidden for backward compatibility.

Description:
When changing the area from normal to NSSA, previous area's
ASBR router's type-5 also calculated and added to routing table along
with Type-7 lsas.
Made a change in route calculation such that it will not consider Type-5
lsas in calculation if it is originated from NSSA ASBR router.
These lsas will be age out at MAX age.

Problem Statement:
==================
on rp_change, PIM processes all the upstream in a loop and for selected
upstreams PIM has to send join/prune based on the RPF changed.
join and prune packets are not getting aggregated in a single packet.
Root Cause Analysis:
====================
on pim_rp_change pim_upstream_update() gets called for selected upstreams.
This API calculates to whom it has to send join and to whom it has to
send prune via API pim_zebra_upstream_rpf_changed(). This API peprares
the upstream_switch_list list per interface and inserts the group and
sources.
Now PIM is still in the pim_upstream_update() API context, i.e PIM
is still processing the same upstream. In the last there is a
call to pim_zebra_update_all_interfaces() which processes the
upstream_switch_list list, sends the packets out and clears the list.
Fix:
====
Don't process the upstream_switch_list in the upstream context.
process all the upstreams prepare the upstream_switch_list and then
process in one go. This will club all the S,G entries.
It also saves list cleanup with respect to memory allocation and
deallocation multiple times.
