WebSocket display: mouse input and adjustable size limits (#1608)

* WebSocket display: mouse input and adjustable size limits

Mouse input was missing from the WebSocket display added in 5.1.0.

- The page reports press, release, drag and wheel on the screen as urwid mouse events.
- Screen.feed() checks the mouse message, moves its position inside the screen,
  and drops it while mouse tracking is off.
- A queued drag of the same button is replaced and wheel steps beyond MAX_PENDING_INPUT
  are dropped, so fast mouse input does not end the session.
- Input is handed over in batches ending at each window resize, at the size it arrived at.
- Screen() and html_page() take max_cols and max_rows. The page fits its screen area to them,
  so clicks beyond the screen are not reported.
- The default limit is 223 x 223, the X10 mouse limit, instead of 200 x 100.
- websocket_tornado.py gains --max-cols and --max-rows.

* websocket_tornado example: user name login and temporary token

- The login needs the user name from --user (default urwid) as well as the token.
- Without --token-file, a new token lives in a private temporary directory removed on exit.
- The addresses and the login are printed at start, the password only for the temporary token.
- SIGHUP stops the server like SIGINT and SIGTERM, so the temporary token is removed.

* input_test: rewrite as a script, add a local WebSocket display

- PEP 723 metadata, nothing run on import, argument parsing in parse_args().
- One runner each for the terminal, CGI and a local WebSocket display.
- --display websocket, offered when Tornado is installed, serves the test on 127.0.0.1:8080
  with a login whose token lives in a temporary directory removed on exit.
- Q asks for confirmation before exiting.

* websocket_tornado example: exit cleanly on Ctrl+C and on a busy port

- Where asyncio has no signal handlers, such as Windows, Ctrl+C cancels serve();
  it now closes every session on the way out and the script exi... (continued)
