Add API to get message path and message destination (#167)

Browse Source 
* Add API to get message path

* Add API to get message destination

* Handle NULL message fields interface and member

Functions sd_bus_message_get_interface() and sd_bus_message_get_member()
can return null in case the message does not use those fields or does
not have them set.
