When the nexthop-groups were added to FRR for some
reason the call to nexthop_group_disable_vrf was
not added although it was written.
Add it in.

Based on the current code, I think the intent was to gracefully handle
vtysh failures and print a useful error message. Barriers in the way of
that:
- Despite reading the results of subprocess.communicate(), there won't
be anything there, because we aren't passing subprocess.PIPE as stdin
and stderr when calling subprocess.Popen()
- Despite catching subprocess.TimeoutExpired, if we were to actually hit
this case frr-reload.py would just crash because it's calling
.communicate() on an unbound process variable, probably a copy-paste
error
- Aside from that, building a kwargs dict to pass to a function that
contains something if something else is not None and nothing if it is,
is pointless when we could just pass the thing itself
Net result is that if vtysh fails to read an frr.conf due to syntax
errors, instead of crashing with a traceback, we actually handle the
error condition, log the problem and vtysh's output, and exit. Actually
we were printing the failed line just by chance because stderr wasn't
captured from the subprocess and I guess showed up as part of systemd's
error capturing or something, but the traceback did a good job of
obscuring that with useless noise.

This function is poorly named; it's really used to allow the FSM to
decide the next valid state based on whether a peer has valid /
reachable nexthops as determined by NHT or BFD.

In a topology like R1 -- R2 -- R5, with R2 being NSSA ABR and R5 being
ASBR redistributing external routes, the ABR R2 will translate type-7
LSA into type-5 and advertise to the backbone. In the current implementation
R2 is also advertising a type-4 LSA when there is no need.
RFC 3101: "...NSSA's border routers never originate Type-4 summary-LSAs
for the NSSA's AS boundary routers, since Type-7 AS-external-LSAs are
never flooded beyond the NSSA's border..."
With this PR a type-4 LSA will not be advertised

The tip hash is only used when we are dealing with
evpn. In bgp_nexthop_self we are doing a memset
irrelevant of whether we will ever find data. Yes
hash_lookup will return pretty quickly.
Modify the code to avoid doing a memset in the case
where the tip hash is empty as that we know we'll
never find anything. With full BGP feeds this
small memset does take some time.

When a MAC is detected duplicate on a local
learn event (with freeze action),
do not send update to bgp to advertise into

With evpn mh, inform_client flag is set and

In the new Sysrepo, all SR_EV_ENABLED notifications are followed by
SR_EV_DONE notifications (assuming no errors occur), so there's no
need to special case the SR_EV_ENABLED event anymore (e.g. do full
transactions in one step).
While here, add a few more guarded debug messages to facilitate
troubleshooting.

Make the sysrepo plugin ignore the deletion of configuration
nodes that don't exist anymore instead of logging an error and
rejecting the changes. This is necessary because Sysrepo delivers
delete notifications for all nodes of a deleted data tree instead
of delivering a single delete notification of the top-level subtree
node (which would suffice for the northbound layer).

From Sysrepo's documentation:
"Note: do not use fork() after creating a connection. Sysrepo
internally stores PID of every created connection and this way a
mismatch of PID and connection is created".
Introduce a new "frr_very_late_init" hook in libfrr that is only
called after the daemon is forked (when the '-d' option is used)
and after the configuration is read. This way we can initialize
the sysrepo plugin correctly even when the daemon is daemonized,
and after the Sysrepo CLI commands are processed (only "debug
northbound client sysrepo" for now).

Currently, when the is-type of an area is changed and its circuits resign,
we are not resetting the DIS flag. Consequently, if the area type is reverted
we are not running the DR election and not regenerating the pseudonode LSP.

When the ASBR stops announcing a prefix into the NSSA area, the LSA
type 7 is removed from the area. However the ABR is refreshing the
type 5 in its LSDB while removing the Type 7 LSA. Routers outside
the area do not get an update.
With this change the LSA type 5 is flushed from the LSDB and the
change is announced to routers outside the area
