	Ensure Rollback Mechanism:
	A rollback's function is a function to rollback a state before ensure's
	function execution.
	When the jump of callcc is across the scope of rb_ensure,
	ensure's functions and rollback's functions are executed appropriately
	for keeping consistency.

	Current API is unstable, and only internal use.

	ruby_register_rollback_func_for_ensure(ensure_func,rollback_func)
	This API create relation ensure's function to rollback's function.
	By registered rollback's function, it is executed When jumpping into
	corresponding rb_ensure scope.
