When looking for a implied host route it is not necessary
to add the `/32` to an ip route add. As such masks
will not be set in this case. Set the value of masks
to a known good value so that when the route installation
fails the test for it actually being there will tell you
that the route is not there -vs- complaining about mask
being uninited.

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This will cause the VPNv6 route to be withdrawn and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.

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.

There is a possibility that the same line can be matched as a command in
some node and its parent node. In this case, when reading the config,
this line is always executed as a command of the child node.
For example, with the following config:
```
router ospf
network 193.168.0.0/16 area 0
!
mpls ldp
discovery hello interval 111
!
```
Line `mpls ldp` is processed as command `mpls ldp-sync` inside the
`router ospf` node. This leads to a complete loss of `mpls ldp` node
configuration.
To eliminate this issue and all possible similar issues, let's print an
explicit "exit" at the end of every node config.
This commit also changes indentation for a couple of existing exit
commands so that all existing commands are on the same level as their
corresponding node-entering commands.
Fixes#9206.

Some BGP updates received by BGP invite local router to
install a route through itself. The system will not do it, and
the route should be considered as not valid at the earliest.
This case is detected on the zebra, and this detection prevents
from trying to install this route to the local system. However,
the nexthop tracking mechanism is called, and acts as if the route
was valid, which is not the case.
By detecting in BGP that use case, we avoid installing the invalid
routes.

Add a new topotest that features a topology with seven routers spread
across four OSPF areas:
* 1 backbone area;
* 1 regular non-backbone area (0.0.0.1);
* 1 stub area (0.0.0.2);
* 1 NSSA area (0.0.0.3).
All routers have both GR and GR helper functionality enabled in
the configuration. The test consists of restarting each router,
one at time, and checking that all forwarding planes (and LSDBs)
are kept intact during those restarts.
A successful run takes about three minutes to finish.
