If there's no default router configured at the moment when bgpd is
connected to zebra, bgpd is not registered as a BFD client.
We should do the registration regardless of the config existence.

If the n-flag-clear option is set in the configuration of a prefix
segment, clear the flag in the extended ip reachability TLVs.
RFCs 7794 and 8667 are not too strict on the setting / clearing the
N-flag in prefix SIDs. However, if there exists a cmd line option
to clear it, it should be cleared in the TLVs announced, as other
vendors do.

If the default route redistribution is configured in OSPF6 router before
the VRF is created, then this is not currently registered in zebra after
the VRF creation.

RIPNG schedules a call to `ripng_interface_wakeup` in 1 second after
receiving the interface UP event from zebra. The function is called even
if the interface was shut down during this interval.
This is incorrect and also leads to a crash in the following scenario:
```
vtysh -c "conf" -c "router ripng vrf red" -c "network enp2s0"
ip link add red type vrf table 1
ip link set enp2s0 vrf red
ip link set enp2s0 down
ip link set enp2s0 up && sleep 2 && ip link del red
```

Track 'down' state of connected addresses with a new flag. We
may have multiple addresses on an interface that share a prefix;
in those cases, we need to determine when the first address
is valid, to install a connected route, and similarly detect
when the last address goes 'down', to remove the connected
route.

This bit of code was cut-n-pasted all over the place:

bpa->afi,
bpa->table_id, true);
