When the client calls \c daemonize(), the \c DaemonFunc should call this
function after initialization and argument parsing to perform the
daemon processing. The \c runFunc should perform the daemon's
main loop, calling \c daemonRunning(true) when it enters the main loop
(i.e. after initialization) and \c daemonRunning(false) when it leaves
the main loop. The \c runFunc is called in a new thread and when the
daemon must exit the main loop due to some external control the
getDaemonQuitMessage() is posted to the thread. This function returns
what \c runFunc returns. \c runFunc should call \c daemonFailed() if
the daemon fails.
