The test verifies that a kernel blackhole route is not affected by
interface's link change.

The `rib_update_handle_kernel_route_down_possibility()` didn't consider
the kernel routes ( blackhole ) without interface. When some other
interfaces are down, these kernel routes will be wrongly removed.

If we set router-id, e.g. `router-id x.x.x.x`, then we have:
```
pc.donatas.net# show ip ospf | include Router ID
OSPF Routing Process, Router ID: x.x.x.x
```
But once we remove it (`no router-id x.x.x.x`), the old router-id remains.
This is kinda OK, but to be consistent with OSPFv3 we should use what Zebra
already has, instead of retaining the old one.

Before this patch, if we set something like:
```
bgp extcommunity-list expanded 1234 permit admin
```
In running config we have:
```
bgp extcommunity-list 1234 seq 5 permit admin
```
That leads to incorrect rendering, even more the line can't be deleted.
With this fix we treat numbered community-list only if it's inside the range
1-500, otherwise it's a non-numbered clist.

Modified nhrp_connection_authorized(). Initially, when writing debug
information about incoming NHRP packets with authentication enabled,
the nhrp_connection_authorized() function would print the
passphrase of the incoming packet as if it were a null terminated
string. This meant that if the passphrase on the incoming packet
had non ASCII-complient bytes in it, it would attempt to print those
bytes anyway. There was also no check that the size of the passphrase in
the incoming packet matched the size of the passphrase on the interface.
The changes in this commit log the passphrase on the incoming packet as
well as the passphrase on interface in HEX to avoid issues with ASCII.
It also performs a check that accounts for the sizes of the two different
passphrases

Modified nhrp_topo topotest to test for newly added resolution
request retry feature. Changes to the topotest include adding a spoke to the
existing nhrp_topo topotest so that a topology with two spokes and hub
can be used to create shortcuts and test the sending/resending of
resolution requests and responses between spoke and hub. The resolution
request retry feature was tested by blocking incoming resolution requests on a
receiving nodes to stop the creation of a successful shortcut - which
then triggered the sending spoke to retry sending resolution requests

Currently the mroute code was not allowing the mroute
to be sent to the dataplane. This leaves us with a
situation where the routes being installed where never
being set as installed and additionally nht against
the mrib would not work if the route came into existence
after the nexthop tracking was asked for.
Turns out all the pieces where there to let this work.
Modify the code to pass it to the dplane and to send
it back up as having worked.

It looks like this aspath is empty, resulting in a size 0 and NULL pointer for path->attr->aspath->segments which leads to the SIGSEGV
fixe: return 0 when segments is null.

This only matters to single hop nodes that are adjacent to the bsr. More common
with IPv6 where LL address is used in PIM as the primary address. If the BSR IP
happens to be an address on the same interface, the receiving pim router
rejects the BSR address because it expects the BSR IP to resolve via the LL address
even if we have a connected route for the same BSR IP subnet. Effectively, we want to
allow rpf to be resolved via secondary IPs with connected routes on the same interface,
and not limit them to primary addresses.
