This class implements common parts of the WebSocket protocol.
It assumes that the WebSocket connection is established. The handshake is
managed in subclasses such as
:class:`~websockets.server.WebSocketServerProtocol` and
:class:`~websockets.client.WebSocketClientProtocol`.
It runs a task that stores incoming data frames in a queue and deals with
control frames automatically. It sends outgoing data frames and performs
the closing handshake.
The `host`, `port` and `secure` parameters are simply stored as attributes
for handlers that need them.
The `timeout` parameter defines the maximum wait time in seconds for
completing the closing handshake and, only on the client side, for
terminating the TCP connection. :meth:`close()` will complete in at most
this time on the server side and twice this time on the client side.
The `max_size` parameter enforces the maximum size for incoming messages
in bytes. The default value is 1MB. ``None`` disables the limit. If a
message larger than the maximum size is received, :meth:`recv()` will
return ``None`` and the connection will be closed with status code 1009.
Once the connection is closed, the status code is available in the
:attr:`close_code` attribute and the reason in :attr:`close_reason`.
