Stream
Follow-up of #4802, which was a requirement for being able to add session typing information to the stream classes.
Some typing definitions are redundant, but since some are not, I chose setting all of them explicitly, to make it more consistent.
The stream classes which I didn't touch are either untyped or don't require any changes. And the other changes are minor typing fixes, removals of redundant stuff (duplicate
self.stream = self.reader.stream
) and updates of legacy py2 code (super()
calls).
