util: correct check of sys.version_info sys.version is a string, and shouldn't be compared against a tuple for version comparisons. This was always true, so we were never disabling gc on 2.6. >>> (2, 7) >= '2.7' True >>> (2, 6) >= '2.7' True

py3: switch to .items() using transformer .iteritems() don't exist in Python 3 world. Used the transformer to replace .iteritems() to .items()

py3: handle multiple arguments in .encode() and .decode() There is a case and more can be present where these functions have multiple arguments. Our transformer used to handle the first argument, so added a loop to handle more arguments if present.

py3: convert to unicode to pass into encode() encoding.encoding is bytes, we need to pass it to encode() which accepts unicodes in py3, so used pycomapt.sysstr() Also this can't be done using transformer as that only transforms the string values not variables.
