The ioctl SIOCGIFCONF does not return IPv6 addresses, so this function
does not work for IPv6 addresses.

Sockets need to be created from sock_daemon_run_send(). This means
that stale socket removal can depend on the PID file context being

BUG: https://bugzilla.samba.org/show_bug.cgi?id=13056
The only time a ctdb_queue is created without valid fd is when CTDB
is trying to establish connections with other nodes in the cluster.
All the other uses always create a ctdb_queue with valid fd.
This avoids queueing up packets for dead nodes or nodes that are not
running in the cluster and stops consuming memory.

Whenever the current git hash changes, we recompile ctdb.c and
ctdb_daemon.c. As both have quite a few warnings with -Wall, this
makes it quite difficult to see the real warnings that pop up during
development. Centralize the ctdb_version_string to just a single file
without warnings.
