        * tracepoint.c (tracepoint_operation): call free_actions instead
        of free.  (free_actions): eliminate some memory leaks for actions.
        (validate_actionline): pass string arg by reference, so we can
        change the pointer.  Change all memrange collection arguments to
        canonical form (literal address and size), to enforce early
        evaluation.  Accept UNOP_MEMVAL (assembly variables) for
        trace collection.  (parse_and_eval_memrange): accept expressions
        for the address and size fields of a memrange (and evaluate
        them immediately).  (several places): use -1 instead of zero
        to distinguish an absolute memrange from a register-relative one.
        (encode_actions): add handling for UNOP_MEMVAL (assembly variable).
