Subject: Make data parameter of expression evaluation functions const

data is a pointer to user-supplied data used for evaluating the expression.  It should not be modified by the evaluation.  Note that this modifies the flesh API to the (undocumented) thorn-visible function Util_ExpressionEvaluate.
