LVS and NAT gateway support had bit-rotted. We don't use any of these
in scripts/tests and we very much doubt anyone else uses them.

For "master", if there is a master then print the PNN, otherwise print
nothing.
For "list", print the PNN and IP addresses without a colon in between.

This simply calls out to the wrapper, so that commands are changed as
follows:
ctdb lvsmaster -> ctdb lvs master
ctdb lvs -> ctdb lvs list
This provides a simple, extensible interface and means that "ctdb lvs
status" is also available.
Unit tests are streamlined so that there is a single test for each
CTDB state. Each test does "master", "list" and "status" sub-tests.

This will replace the ctdb CLI tool "lvs" and "lvsmaster" options. It
also makes LVS daemon support unnecessary.

This made sense when connections were individually queued in the
daemon. However, they're now done in batch so just keep an overall
count.

When previously killing TCP connections via the daemon there was some
latency due to each kill being sent to the daemon via a separate
control. This probably meant that when doing a 2-way kill the tickle
ACKs sent to the client end of a connection would not interfere with
listening for the reply ACK from the server end. Now that there is no
latency, the tickle ACK or RST sent to the client end can be seen as
the reply to the server end tickle ACK, and vice-versa.
To avoid this, throw away packets that look like we sent them.

This will allow killing of TCP connections without daemon involvement.
It looks strange that the common code for daemon and helper is in the
server directory. Having it in the server directory means less
temporary changes to the build configuration. This code will move
into the helper itself and will no longer be used by the daemon.

These have been scattered around the code so that
tevent_loop_allow_nesting() can be called. However, only the main
daemon and some tests currently use nested event loops.
TEVENT_DEPRECATED is already defined in the places where it is needed.

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.

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.
