largefiles: always use filechunkiter when iterating files Before, we would sometimes use the default iterator over large files. That iterator is line based and would add extra buffering and use odd chunk sizes which could give some overhead. copyandhash can't just apply a filechunkiter as it sometimes is passed a genuine generator when downloading remotely.
