* Cleanup gather(): use cancelled() method instead of using private Future
attribute
* Fix _UnixReadPipeTransport and _UnixWritePipeTransport. Only start reading
when connection_made() has been called.
* Issue #23333: Fix BaseSelectorEventLoop._accept_connection(). Close the
transport on error. In debug mode, log errors using call_exception_handler()
* _SelectorTransport constructor: extra parameter is now optional
* Fix _SelectorDatagramTransport constructor. Only start reading after
connection_made() has been called.
* Fix _SelectorSslTransport.close(). Don't call protocol.connection_lost() if
protocol.connection_made() was not called yet: if the SSL handshake failed or
is still in progress. The close() method can be called if the creation of the
connection is cancelled, by a timeout for example.
* Remove unused SSLProtocol._closing attribute
* test_sslproto: skip test if ssl module is missing
* Python issue #23208: Don't use the traceback of the current handle if we
already know the traceback of the source. The handle may be more revelant,
but having 3 tracebacks (handle, source, exception) becomes more difficult to
read. The handle may be preferred later but it requires more work to make
this choice.
Use a coroutine with asyncio.sleep() instead of call_later() to ensure that the
schedule call is cancelled.
Add also a unit test cancelling connect_pipe().
Increase http.client.HTTPConnection test coverage.
Added a new tunnel test to verify setting of _tunnel_host, _tunnel_port,
_tunnel_headers attributes on HTTPConnection object.
script_helper.assert_python_failure(). No such feature has ever existed,
thus it doesn't do what the comment claims. (It does add a 'without'
variable to the environment of the child process but that was not intended)

mode. Explicitly remove the PYTHONFAULTHANDLER environment variable before
launching a child interpreter when its presence would impact the test (the
reason -E was being used in the first place).
This enables running the test in an environment where other Python environment variables must be set in order for things to run (such as using PYTHONHOME to
tell an embedded interpreter where it should think it lives).
