struct ctdb_public_ip_list is a fixed size structure and introduces an
extra level of indirection. This means one level of indirection can
be dropped for known_public_ips and available_public_ips.

_cluster_is_recovered() is used to check if all the nodes in the
cluster have recovery mode set to NORMAL. This is mainly used just
after recovery to wait till the recovery is over. Instead just check
the recovery mode on node 0.

This is unnecessary in Samba >= 4.0 because winbindd monitors IP
address itself and no longer needs to be told when they are dropped.
The smbcontrol commands can hang if a node has recovery mode active
because smbcontrol is unable to connect to the registry. Therefore,
the smbcontrol commands should be removed.

This reverts commit 0ff90f4fac74e61192aff100b168e38ce0adfabb.
BUG: https://bugzilla.samba.org/show_bug.cgi?id=11707
The checks against database generation are not required since
the global generation is updated as part of updating vnnmap
before the actual database recovery. This change was done in
5aab31a39a3589b910a78b96071d6aa5e6547696.
Checking only against the database generation is incomplete. It can
cause CTDB to abort if the following sequence of events happen.
- CTDB gets REQ_DMASTER packet (gen1)
This packet processing gets deferred to get a record lock
- CTDB goes into recovery, marks RECOVERY_ACTIVE
CTDB recovery helper updates vnnmap (gen2)
- CTDB processes REQ_DMASTER packet (gen1)
The check against database generation (gen1) succeeds.
The check for lmaster is now invalid because VNNMAP has changed.
This will cause CTDB to abort due to protocol error.
Reverting the patch stops processing packets of older generation before
they get into call processing.

This means that the NAT gateway capability in the daemon is now

The "natgwlist" command is no longer marked "auto all" and is also
marked "without daemon". That latter is not strictly true because
ctdb_natgw needs the daemon so a subsequent invocation of "ctdb
nodestatus" will work. However, "without daemon" is used here because
the top-level "ctdb natgwlist" does not need to open a connection to
the daemon. It just needs to invoke ctdb_natgw.
Update tests to suit.
It would make sense to make "ctdb natgw" generally call out to
ctdb_natgw, passing all argument. However, that can be done later.

Handle the "slave-only" option in the unit test setup. Reindent

Also drop a test that no longer makes sense. Specifying both "master"
and "slave-only' is now much more obvious, since they need to be on
the same line, and is now punishable by undefined behaviour.

Some features, such NAT gateway and LVS support, can be implemented
without daemon and (internal) ctdb CLI tool support. These are
non-core features that don't need incredible performance and they
don't need to be in the core code. They can easily be reimplemented
in scripts, along with some configuration changes.
For continuity, the ctdb CLI tool code will call out to helper scripts
so that the current status information can still be provided. Those
helper scripts may then reinvoke the ctdb CLI tool to gather
information.
So, redo the tool testing using a "ctdb" stub command. This will
swallow standard input and feed it to the test program each time the
"ctdb" stub is called.

This is intended to replace the use of "ctdb natgwlist" in 11.natgw
and provide different views of the NAT gateway status.
It replaces the use of CTDB_NATGW_SLAVE_ONLY=yes with a "slave-only"
keyword in the NAT gateway nodes file. This means the nodes file must
be consistent on all nodes in a NAT gateway group.
Note that this script is not yet integrated, so there are no behaviour
or documentation changes.
