I'm 100% certain I've forgotten to merge something, but the main code
should be in. It's mainly in dbwrap_ctdb.c, ctdbd_conn.c and
messages_ctdbd.c.
There should be no changes to the non-cluster case, it does survive make
test on my laptop.
It survives some very basic tests with ctdbd enables, I did not do the
full test suite for clusters yet.
Phew...
