* library/safe.tcl: A series of patches which bring the SafeBase

	up to date with code guidelines, Tcl's features, also eliminating
	a number of inefficiencies along the way.
	(7) Replaced the remaining uses of 'Set' and others outside of the
	path/token handling, and deleted a number of procedures related to
	state array access which are not used any longer.
