* xfns.c: Make resource manager work correctly even when

	Vinvocation_name has periods and asterisks in it.
	(Vxrdb_name): New variable.
	(Fx_get_resource): Use it instead of Vinvocation_name.
	(Fx_open_connection): Initialize it to a copy of Vinvocation_name,
	with the dots and stars replaced by hyphens.
	(syms_of_xfns): staticpro it here.

	* xfns.c (Fx_get_resource): Use the proper format string when the
	attribute has been specified.
