sockaddr_in6, so we were writing out of boundaries. Use struct
sockaddr_storage instead.

Fix build on Python 3
Never raise StreamError directly

Raise the appropriate exception instead, that is, TCPError, PipeError or
TTYError. StreamError serves as the base class for those 3, so a stream
type agnostic piece of code could catch StreamError and not bother about
the stream type.
