renamed tokenize and now works with bytes rather than strings. A new
detect_encoding function has been added for determining source file encoding
according to PEP-0263. Token sequences returned by tokenize always start
with an ENCODING token which specifies the encoding used to decode the file.
This token is used to encode the output of untokenize back to bytes.
