Started out as progress towards python#1476, but I ended up fixing a few more things: - fixed the signature of _encode_type, which actually returns a pair, not a string - made some attributes into properties in order to prevent the descriptor protocol from turning them into methods - found a bug in CPython in the process (python/cpython#6779) I used the following test file to make sure these classes are now instantiable: ```python import codecs import io from typing import IO bio = io.BytesIO() cod = codecs.lookup('utf-8') codecs.StreamReaderWriter(bio, codecs.StreamReader, codecs.StreamWriter) codecs.StreamRecoder(bio, cod.encode, cod.decode, codecs.StreamReader, codecs.StreamWriter) ```

Probably needs a test. |

Just added a test. (There were no tests at all for StreamRecoder, so I also added a test for the write() method.) |

The CI errors don't look real. |

|
