	* glib/dbus-gproxy.c (dbus_g_proxy_invoke): New method; calls
	to this are generated for client-side wrappers.  Invokes a
	D-BUS method and returns reply values.

	* glib/dbus-binding-tool-glib.c (write_args_sig_for_direction): New
	function; writes signature string for argument direction.
	(write_args_for_direction): Change to pass input values directly
	instead of via address, and fix indentation.
	(generate_client_glue): Change to invoke dbus_g_proxy_invoke.  Also
	make generated wrappers inlineable.

	* dbus/dbus-message.c (dbus_message_iter_get_fixed_array): Add
	note about using dbus_type_is_fixed.

	* dbus/dbus-marshal-basic.c (_dbus_type_is_fixed): Moved to
	dbus/dbus-signature.c as dbus_type_is_fixed.

	All callers updated.

	* dbus/dbus-signature.c (dbus_type_is_fixed): Moved here
	from dbus/dbus-marshal-basic.c:_dbus_type_is_fixed.

	* dbus/dbus-signature.h: Prototype.

	* glib/dbus-binding-tool-glib.c (compute_marshaller_name): Fix
	error printf code.

	* test/glib/test-dbus-glib.c (main): Be sure to clear error as
	appropriate instead of just freeing it.
	(main): Free returned strings using g_free.

	* test/glib/Makefile.am (test-service-glib-glue.h)
	(test-service-glib-bindings.h): Add dependency on dbus-binding-tool.

	* glib/dbus-gvalue.c (MAP_BASIC): Refactored from MAP_BASIC_INIT;
	simply maps a simple D-BUS type to GType.
	(dbus_dbus_type_to_gtype): Function which maps D-BUS type to
	GType.
	(dbus_gvalue_init): Just invoke dbus_dbus_type_to_gtype and
	initialize the value with it.
	(dbus_gvalue_binding_type_from_type): Unused, delete.
	(dbus_gvalue_demarshal): Switch to hardcoding demarshalling for
	various types instead of unmarshalling to value data directly.
	Remove can_convert boolean.
	(dbus_gvalue_marshal): Remove duplicate initialization; switch to
	returning directly instead of using can_convert boolean.
	(dbus_gvalue_store): New function; not related to D-BUS per-se.
	Stores a GValue in a pointer to a value of its corresponding C
	type.

	* glib/dbus-gvalue.h: Remove dbus_gvalue_binding_type_from_type,
	add dbus_gvalue_store.
