Summary: In `Config`, the lists generated by `mk_string_list`, `mk_path_list`, `mk_rest_actions` are reversed implicitly, which made it hard for developers to use them correctly. What this and the next diff will do is to change the list variables of the `Config` to not-reversed one. * diff1: First this diff adds `RevList` to distinguish reversed lists explicitly. All usages of the reversed list should be changed to use `RevList`'s lib calls. * diff2: Then the next diff will change types of `Config` variables to not-reversed, normal list.
