67432fb9b9 messages_ctdb: Add messaging_ctdb_connection
This will be the replacement for messaging_ctdbd_connection(). This does not
default to initializing messaging but panics. We just don't have correct
default arguments for messaging_init. Implicit multiple messaging and event
contexts is a bug also.

It *might* be that some tools fail due to this, but this needs fixing in
different ways. See the previous commit for smbpasswd.

1cc970be02 dbwrap_ctdb: Use messaging_ctdbd_connection
With messages_ctdb, the global ctdb connection will change after fork.

Don't store the wrong parent connection across a fork. The alternative would
be to do a reinit on all dbwrap_ctdb databases, but that seems overkill
given that we only have one "standard" ctdb connection anyway.

5afdce0a6a messaging: Add messaging_ctdb_init/destroy
This models connecting to ctdb after the dgm code. The main point
is that we should never open more than more ctdb socket for messaging.

With more than one socket, we might end up with our pid registered with
ctdb on more than one socket. This could lead to memory overconsumption
in ctdb. ctdbd will eventually throw away messages, but they will take
up space unnecessarily.

332b179143 smbldap: expose bind callback via API and increase smbldap ABI version
Until we fully migrate to use gensec in smbldap, we need to continue
exposing bind callback to allow FreeIPA to integrate with smbldap.

Since smbldap API is now lacking direct access to 'struct
smbldap_state' and new API functions were added to give access to
individual members of this structure, it makes sense to increase ABI
version too.

a2436b67e5 messaging: Deliver messages only once
This survived an autobuild, so no subsystem strictly needs this anymore. In
particular the notify subsystem has been rewritten.

Why this patch? It removes some complexity from core code, and it reduces the
potential memory overconsumption: Right now I'm working on a g_lock_ping_pong
test. This test does a lot of messaging_filtered_read_send calls in a tight
loop on a nested event context. With the current code we let the
messaging_filtered_read code consume the message that arrives, but it also
posts it for consumption by the main event context attached to the messaging
context with its "classic" callback. This test never comes back to the main
event context, so it accumulates more and more self-posted messages. That's
just unnecessary, given that due to the successful autobuild nothing but the
read1 test makes use of the "multicasting" of messages.
