[New-bugs-announce] [issue26509] spurious ConnectionAbortedError logged on Windows

[Sebastien Bourdeauducq]

New submission from Sebastien Bourdeauducq:

https://github.com/python/asyncio/issues/319

On Windows, asyncio servers sometimes print such log messages when clients disconnect:

```
ERROR:master:asyncio:Fatal write error on pipe transport
protocol: <asyncio.streams.StreamReaderProtocol object at 0x0000000003F63FD0>
transport: <_ProactorSocketTransport fd=756>
Traceback (most recent call last):
  File "C:\Users\User\Miniconda3\lib\asyncio\proactor_events.py", line 283, in _loop_writing
    self._write_fut = self._loop._proactor.send(self._sock, data)
  File "C:\Users\User\Miniconda3\lib\asyncio\windows_events.py", line 450, in send
    ov.WSASend(conn.fileno(), buf, flags)
ConnectionAbortedError: [WinError 10053] An established connection was aborted by the software on your host machine.
```

I guess that this line:
https://github.com/python/asyncio/blob/39c135baf73762830148236da622787052efba19/asyncio/proactor_events.py#L291

should be changed to also catch ``ConnectionAbortedError``, as this exception also happens when connections are closed on Windows, in addition to ``ConnectionResetError``.
