leader.  This is useful for catching messages from lyskomd that
	are created by libraries that we have no control over, and that
	don't emit the expected line leader.
(set_debug_calls): New proc, extracted from lyskomd_start and
	lyskomd_fail_start.  Expect the new message that is emitted
	when the debug calls are disabled.
(lyskomd_start): New optional argument: pre_lock_messages.  Moved
	code to set_debug_calls().
(lyskomd_fail_start): Ditto.
