/**
* upstart_open:
* @parent: parent object for new proxy.
*
* Opens a connection to the Upstart init daemon and returns a proxy
* to the manager object. If @dest_name is not NULL, a connection is
* instead opened to the system bus and the proxy linked to the
* well-known name given.
*
* If @parent is not NULL, it should be a pointer to another object
* which will be used as a parent for the returned proxy. When all
* parents of the returned proxy are freed, the returned proxy will
* also be freed.
*
* Returns: newly allocated D-Bus proxy or NULL on raised error.
