no point in scheduling an LSP refresh immediately if we know it is
going to be postponed again due to the network still being in its
instability grace period

when we receive an event from BFDD and we end up throwing it away,
make sure that we log (with debug guards) the reason for this, so
we can troubleshoot issues like the one addressed by the previous
commit.

A wrong check was silently skipping the initialization of the bfd_session
struct in the adjacency if the router was not configured for IPv6. This
would cause BFD events to be ignored regardless of the configuration.
Also add a function to return the "name" of an adjacency and use it in a
couple of places, including the new log, instead of repeating the same
code in a bunch of places.

The previous, more complex mechanism failed to take into account that
git worktrees only have a stub .git file & copying the worktree itself
is not enough. Just extract a file list beforehand & don't bother with
git inside the container.

This prevents a failed IPSec connection from preventing DMVPN from working.
A failure situation can be reproduced using a Cisco peer, and and disabling then
re-enabling the tunnel IPSec protection (after the IPSec connection has
already been established).

If we have a SAFI conflict, ie we are trying to activate safi's
UNICAST and LABELED_UNICAST at the same time, we should not
cause bestpath to be rerun and we should not try to put
labels on everything.

This bug was first reported in PR#7717. When removing an interface
from the area, the interface prefix is still shown
r1# sh ipv6 ospf6 interface prefix
*N IA 2013:12::/64 ::1 r1-r2-eth0 00:00:12
r1# conf t
r1(config)# router ospf6
r1(config-ospf6)# no interface r1-r2-eth0 area 0.0.0.0
r1(config-ospf6)# exit
r1# sh ipv6 ospf6 interface prefix
*N IA 2013:12::/64 ::1 r1-r2-eth0 00:00:22
This fix will check if the interface is disabled so the
prefix is not shown

In OSPFv3 when removing the interface from an area, all ospf6
interface commands are lost, so when changing the area you need
to reconfigure all ospf6 interface commands again
r1# sh run
interface r1-r2-eth0

ipv6 ospf6 dead-interval 4
ipv6 ospf6 hello-interval 1

This is because the interface is being deleted instead of disabled
(see PR#7717) I believe the interface should be left as disabled
(not deleted) when removing the interface from the area

Currently there is a single interval for both RX and TX echo functions.
This commit introduces separate RX and TX timers for echo packets.
The main advantage is to be able to set the receive interval to zero
when we don't want to receive echo packets from the remote system.
