	Make SessionRelay and SessionDirect (was Session) implement a common
	interface GdmSession.  Push some code that lived in the simple and product
	slaves into the SessionDirect class.  Using an interface has a few
	advantages besides ensuring consistency: makes it easier to do some
	abstraction in the slave classes, makes it possible to more easily
	implement other non-pam backends.

	Add a stub for a selected-user-changed signal from the session interface.
	This will be used to update the user selection in the greeter when the
	user is set from the backend.
