	renamed low level function-as-opposed-to-closure objects
		as SIMPLE-FUN to disambiguate the old nasty
		(DEFPARAMETER *FUNCTION-HEADER-TYPES*
		  (LIST FUNCALLABLE-INSTANCE-HEADER-TYPE
			FUNCTION-HEADER-TYPE ; <- source of confusion
			CLOSURE-FUNCTION-HEADER-TYPE
			CLOSURE-HEADER-TYPE))
	..generally s/%function/%simple-fun/
	..also s/%fun-type/%simple-fun-type/
	..s/function-code-header/fun-code-header/
	..Generally matches to "-i 'function.*header'" become
		corresponding 'simple.*fun.*header'.
	s/function-header-word/simple-fun-header-word/
	s/function-pointer-type/fun-pointer-type/
	..also similarly matches to 'function.*slot'
	CHECK-FUNCTION-OR-SYMBOL is no longer used, probably because
		function names can be (SETF FOO) now. Delete it.
	Similarly, SYMBOL-FUNCTION-SLOT is no longer used. Delete it.
	Dunno why SYMBOL-SETF-FUNCTION-SLOT is no longer used --
		FDEFNs, probably -- but by now you know the drill.
	and SYMBOL-RAW-FUNCTION-ADDR-SLOT, too
	back to SIMPLE-FUN and friends..
	.."closure.*function.*header" to "closure.*fun.*header"
	..s/scav_function_header/scav_fun_header/
	..tweaked DEFINE-PRIMITIVE-OBJECT (FUNCTION ..) to use
		SIMPLE-FUN name
	..s/%fun-type/%simple-fun-type/
	..s/%fun-name/%simple-fun-name/
	..s/%fun-arglist/%simple-fun-arglist/
	..s/%fun-self/%simple-fun-self/
	..s/%fun-next/%simple-fun-next/
	Also substitute s/function/fun/ in slot names defined in
		objdef.lisp, e.g. CLOSURE-FUN.
