r23806: update Samba4 with the latest ctdb code.

This doesn't get the ctdb code fully working in Samba4, it just gets
it building and not breaking non-clustered use of Samba. It will take
a bit longer to update some of the calling ctdb_cluster.c code to make
it work correctly in Samba4.

Note also that Samba4 now only links to the client portion of
ctdb. For the moment I am leaving the ctdbd as a separate daemon,
which you install separately from http://ctdb.samba.org/.

+    <para>
+      onnode is a utility to run commands on a specific node of a CTDB
+      cluster, or on all nodes.
+    </para>
+    <para>
+      The NODE option specifies which node to run a command on. You
+      can specify a numeric node number (from 0 to N-1) or the special
+      node 'all'.
+    </para>
+    <para>
+      The COMMAND can be any shell command. The onnode utility uses
+      ssh or rsh to connect to the remote nodes and run the command.
+      </para>
+    <para>
+      If the COMMAND starts with a /, then the command is run via the
+      'at' service. Otherwise the command is run in the foreground.
+    </para>
