0.8.4.30:
	Be more careful over automatically generated generic function
	lambda lists
	... when generating PCL-internal GFs, pass :LAMBDA-LIST to
		ENSURE-GENERIC-FUNCTION
	... when generating accessor GFs, pass :LAMBDA-LIST if the
		function is not already created (where you want to
		preserve the user's lambda list instead)
	... tests for required behaviour
	Adjust INVALID-FASL patch slightly
	... comment in package-data-list.lisp-expr
	... remove unneccessary sb!ext:: prefixes
