I can just assume this is a bad hack for a condition that should have been
fixed in a different way. Today we pretty much expect a messaging_context to be
properly initialized everywhere, and this includes a ctdb connection.
If something later fails due to this commit, we need to do a
messaging_init before the offending call

The only reason for this complex monster was an overload of ctdbd.
When opening files, we unconditionally checked all share modes for
validity. This meant thousands of serverid_exists calls per second
for popular directories. This has long gone, now we only check for
validity if a conflict happens.
The only remaining caller is net serverid wipedbs, an administrative
command. If that loads ctdbd, so be it.

This is a relevant change: I was experimenting with
server_id_db_set_exclusive() in "net" and got failures all over the
place. The main reason was that "net" by default does not do a
serverid_register. With messaging_dgm we have the process' unique
id available via the lockfile contents. Using open/read/close is a
bit slower than local tdb access, but this version is safe for all
processes which have done messaging_init()

If there's another process around there will typically be at most
one process. So there is no real need to run the plural version of
serverid_exists.

It took a bit for me to figure out what the rec_key parameter to

In Samba 4.2, we used lock_path("msg") (with 0700) for the socket directory,
while we use lock_path("msg") (with 0755) for the lock file directory.
This generates a conflict that prevents samba, smbd, nmbd and winbindd
from starting after an upgrade.
