Add support for upstart's expect stop protocol
Add support for upstart's expect stop daemon synchronization method.
When starting remctld in stand-alone mode with upstart, pass the new
-Z option to remctld, and it will raise SIGSTOP when ready to accept
connections, signaling to upstart that the daemon has fully started.
