The usage of json_object_to_json_string_ext is meant for
generation of output string and returns a `char *` pointer
to the `formatted` output. Just calling it does nothing
and it's expensive to boot.
Modify the code in ospfd to just output with the NOSLASHESCAPE
when outputting.

If the SRv6 locator is deleted in zebra, zclient(bgpd)
which allocates SIDs from the locator will update the
RIBs which use those SIDs and make them invalid.
This will cause the VPNv6 route to be withdrawn and
the VPN to stop.
If the SRv6 locator is added again, zclient(bgpd) will
allocate the SIDs from the locator again, and VPNv6
will be re-established.
This commit add a test case to confirm this.

Before this PR, in case of get locator chunk zapi from
zclient, zebra precreated a down state locator and set
the chunk ownership. After this PR, this is no longer
done, and chunks are no longer automatically generated.
In this commit, we will make a test update to check the
corresponding detailed behavior.

When running bgp evpn rt5 setup with vrf namespace backend, once the
BGP configuration loaded, some refresh like the config change of a
vxlan interface is not taken into account. As consequence, the BGP
l2vpn evpn entries are empty. This can happen by recreating vxlan
interface like follows:
ip netns exec cust1 ip li del vxlan1000
ip link add vxlan1000 type vxlan id 1000 dev loopback0 local 10.209.36.1 learning
ip link set dev vxlan1000 mtu 9000
ip link set dev vxlan1000 netns cust1
ip netns exec cust1 bash
ip link set dev vxlan1000 up
ip link set dev vxlan1000 master br1000
Actually, changing learning attribute requires recreation, and this
change needs to manually reload the frr configuration.
The update mechanism in zebra about vxlan interface updates is
already put in place, but it does not work well with namespace
based vrf backend. The function zl3vni_from_svi() is then
modified to parse all the interfaces of each namespace.

Description:
Change is intended for fixing the following issues related to vrf route leaking:
Routes with special nexthops i.e. blackhole/sink routes when imported,
are not programmed into the FIB and corresponding nexthop is set as 'inactive',
nexthop interface as 'unknown'.
While importing/leaking routes between VRFs, in case of special nexthop(ipv4/ipv6)
once bgp announces route(s) to zebra, nexthop type is incorrectly set as
NEXTHOP_TYPE_IPV6_IFINDEX/NEXTHOP_TYPE_IFINDEX
i.e. directly connected even though we are not able to resolve through an interface.
This leads to nexthop_active_check marking nexthop !NEXTHOP_FLAG_ACTIVE.
Unable to find the active nexthop(s), route is not programmed into the FIB.
Whenever BGP leaks routes, set the correct nexthop type, so that route gets resolved
and correctly programmed into the FIB, in the imported vrf.

Create a pid file for the router created by topotest.
By executing nsenter directly against this pid, developers
can execute commands directly from outside the unet shell.
This allows the developer to use script, tab completion, etc.,
and improves efficiency.

- Reduce OSPF timers to 1 and 4
- Reduce BGP connect timer to 5
- Apply configs in parallel as single file
- Remove the switches as all links are p2p, perhaps this will help with
reliability?

- The PIM tests do not need kernel routes to help them bind joins and
sources to specific interfaces. They should do that themselves directly.
Also do not change system wide "rp_filter" sysctl away from the value
required by everyone else.
