Problem:
When IP1:M1 (local) moved to IP1:M2 (remote-VTEP) bgpd continues to
advertise IP1:M1.
Fix:
Local path del is sent to bgp if the neigh was {local-active||peer-active}.
So path del needs to be called before the sync flags (including peer-active)
are cleared.

When we hand set the router-id, but we have choosen a router-id
that is already the `winner` there is no point in updating anyone
with this data.

At startup there exists a time frame where we might not know
a particular vrf's router id. When zebra gets a request for
it let's not just blindly send whatever we have. Let's be
a bit smart and only respond with one if we have one.
The upper level protocol can wait for it to have one.

vrf_name_to_id() returned VRF_DEFAULT when the vrf name was
unknown, hiding errors. Per community recommendation, vrf_name_to_id()
is now removed and the few callers now use vrf_lookup_by_name()
directly.

Add a knob to turn a NSSA area into a totally stub area. In this
configuration a Type-3 default summary route is generated by default.
Syntax: `area A.B.C.D nssa no-summary`.

Several functions in ospf_vty.c were allocating json memory
irrelevant if it was needed or not and then at the end of the loop
free'ing it if it was not used. Clean up the access pattern.

The usage of json_object_to_json_string_ext is mean 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 bgpd to just output with the NOSLASHESCAPE
when outputting.

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.

Refactor the bgp_auth test to create common_config code to allow
non-json based tests to reset routers and load configs in parallel.

- 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.
