Use the already existing mpls label code to store VNI
info for vxlan. VNI's are defined as labels just like mpls,
we should be using the same code for both.
This patch is the first part of that. Next we will need to
abstract the label code to not be so mpls specific. Currently
in this, we are just treating VXLAN as a label type and storing
it that way.

1. When OSPF unnumbered neighbor doesn't exist in any VRF,
OSPFD prints a bunch of empty JSON objects. Fixed it
by adding an outer JSON object with VRF information in it
2. Added "vrf" option to this command so that per VRF
unnumbered OSPF neighbor information can be retrieved
JSON output:

When show ip ospf border-routers json (without vrf)
specificed, it leads to crash if there no border-routers
information.
Fix:
Do not free json object if use_vrf flag (means vrf option
is not passed) is not set.
Ticket:#3229017
Issue:3229017
Testing Done:
with fix:
l1# show ip ospf border-routers json
{
}
l1# show ip ospf vrf default border-routers json
{

Don't directly use `time()` for generating sequence numbers for two
reasons:
1. `time()` can go backwards (due to NTP or time adjustments)
2. Coverity Scan warns every time we truncate a `time_t` variable for
good reason (verify that we are Y2K38 ready).

indication LSAs, on backbone and non-backbone areas in different
scenarios.

Description:
Code changes involves.
1. Count the no.of router LSAs received with DC options bit set,
supporting do not age(DNA).
2. If no of router LSAs received with DC bit set is equal to total
no of LSAs in the router lsdb, then all the routers in the
area support do not age processing.
3. Flood the self originated LSAs with DNA flag if all routers in the area
supports the feature.
4. Stop aging of the LSAs recived with DO_NOT_AGE bit set from
other routers.
5. Self originated DO_NOT_AGE lsas will still be aging in their own
database.

a) if show_function happened to be NULL we would leak json memory
b) json_lsa_type was being allocated but only used in the default case, leaking memory
c) json output would sometimes produce text output and that is incorrect

Fix the following problems:
- Always free vertex next hops on `vertex_parent_free`
- Signalize failure on `ospf_spf_add_parent` when parent already exists
so the caller has the chance to `free()` any allocated resources.
- Don't reuse vertex next hops without the reference count logic in
`ospf_nexthop_calculation`. Instead allocate a new copy so it can be
`free()`d later without complications
