- added --self-connect option to ctdb_test, allowing testing when a node connects to itself. not as efficient as local bypass, but very useful for testing purposes (easier to work with 1 task in gdb than 2) - split the ctdb_call() into an async triple, in the style of Samba4 async functions. So we now have ctdb_call_send(), ctdb_call_recv() and ctdb_call(). - added the main ctdb_call protocol logic. No error checking yet, but seems to work for simple cases - ensure we initialise the length argument to getsockopt() (This used to be ctdb commit 95fad717ef5ab93be3603aa11d2878876fe868d3)
