/** \brief daemon utility.
\param progname program name for logging purposes.
\param flags flags which is a bit-wise combination of YAZ_DAEMON_..
\param work working handler (which may be running in different process)
\param data opaque data to be passed to work handler
\param pidfile filename with Process-ID (NULL for no file)
\param uid effective user ID for handler (NULL for no same as caller)
\returns 0 for success, non-zero for failure.
This function puts calls work handler which is supposed to carry
out a daemon service with a possible changed User ID and in a
child process.
Flag YAZ_DAEMON_FORK: Puts the service in the background on Unix.
Flag YAZ_DAEMON_DEBUG: Puts the service in debug mode (no fork at all).
Flag YAZ_DAEMON_KEEPALIVE: Repeatedly calls work handler if it makes a
"fatal" error.
