	* test/decode-gcov.c (function_solve_graph): make broken block
	graph a nonfatal error since it seems to be broken. Need to debug
	this.

	* dbus/dbus-marshal.c (_dbus_type_is_valid): new function since we
	can't just check type > INVALID < LAST anymore

	* dbus/dbus-message.c (dbus_message_get_signature): new function
	(dbus_message_has_signature): new function
	(struct DBusMessage): add signature field (right now it isn't sent
	over the wire, just generated on the fly)
	(dbus_message_copy): copy the signature, and init strings to
	proper length to avoid some reallocs
	(dbus_message_iter_init_array_iterator): return void, since it
	can't fail
	(dbus_message_iter_init_dict_iterator): return void since it can't fail
	(_dbus_message_loader_queue_messages): add silly temporary hack to
	fill in message->signature on load

	* dbus/dbus-protocol.h: change DBUS_TYPE_* values to be ASCII
	characters, so they are relatively human-readable.
