Every caller that expects to receive something needs to check if enough was sent. Make this check mandatory for everyone. Yes, this makes the parameter list for cli_trans a bit silly, but that's just the way it is: A silly protocol request :-) While there, convert some _done functions to tevent_req_simple_finish_ntstatus.
