- Change the return type of create_connection, start_tls,
connect_accepted_socket, create_unix_connection to Transport
rather than BaseTransport (closes#9199).
- Change the return type of create_datagram_endpoint to
DatagramTransport rather than BaseTransport.
- Change the argument of sendfile to WriteTransport rather than
BaseTransport.
I considered also changing the argument of start_tls to Transport, but
I think that will give false positives for code that implements a custom
transport class that inherits from both ReadTransport and WriteTransport
but not from Transport, and I'm not sure if typing has a way to express
an intersection of types. Since users are not normally expected to
implement transports that may be overthinking things.
* Adapt number types in ast
Since mypy 0.990 type promotions was limited.
This means that complex is not longer promoted to int/float, therefore
we should adapt the types to list all possible types

- The _MessageData alias refers to objects handled in the
_dump_message method: 016c7d37b6/Lib/mailbox.py (L210)
- The path passed to __init__ should be a str path because there are
many places in the file (search for self._path) where we join it
with a str, which won't work with a bytes path.
Technically some uses of `pwd` accept more types, but others
use `isinstance()` to enforce only `bytes`. It seems better to
keep the same type throughout the module.
