* eval.c (unbind_catch): Do the long-jump here.  Take a VALUE
	argument, which specifies the value to return to the catch, or the
	data to give to the condition handler.  Renamed to
	unwind_to_catch, to reflect new role.
	(Fsignal, Fthrow): Removed code to set catch tag value and do the
	long-jump; this is taken care of by unwind_to_catch.
