DBus: Add a peer example to test the DBusServer class.

	* gio/src/dbusconnection.{ccg,hg}:  Reorder the VariantBase
	'parameters' parameter in the call*() methods to come after the
	method_name parameter.
	* gio/src/dbusintrospection.hg: Use refreturn for methods where the C
	API does not automatically reference the return.
	* gio/src/dbusserver.{ccg,hg}: Add non-observable constructors and
	create() methods.
	* glib/src/variant.{ccg,hg} (create_tuple): Renamed from create().
	Write this method to be more specific for tuples (it's probably the
	only case where this method might be used).  Dealing with tuples still
	feels awkward with the method.  Maybe there's a better way.

	* examples/Makefile.am:
	* examples/dbus/peer.cc:
	* examples/dbus/userbus.cc:
	* examples/dbus/well-known-address-client.cc: Add the new
	server/client peer example (named peer).  The example crashes because
	the C API seems to not deal with empty strings "" well, but at least
	there is now an example.  Making sure it runs well is necessary.  Also
	rename the previous example to userbus.cc.
