BaseSelectorEventLoop.sock_connect()
There is a race condition in create_connection() used with wait_for() to have a
timeout. sock_connect() registers the file descriptor of the socket to be
notified of write event (if connect() raises BlockingIOError). When
create_connection() is cancelled with a TimeoutError, sock_connect() coroutine
gets the exception, but it doesn't unregister the file descriptor for write
event. create_connection() gets the TimeoutError and closes the socket.
If you call again create_connection(), the new socket will likely gets the same
file descriptor, which is still registered in the selector. When sock_connect()
calls add_writer(), it tries to modify the entry instead of creating a new one.
This issue was originally reported in the Trollius project, but the bug comes
from Tulip in fact (Trollius is based on Tulip):
https://bitbucket.org/enovance/trollius/issue/15/after-timeouterror-on-wait_for
This change fixes the race condition. It also makes sock_connect() more
reliable (and portable) is sock.connect() raises an InterruptedError.

Without this reset, starttls would fail if a connect/starttls was done after a
quit, because smtplib assumed the existing value of emspt_features was
accurate, but it gets reset when starttls completes (and the new value does
not contain the starttls capability, since tls is already started at that
point). (There may be additional places where this lack of reset was an
issue as well.)

Don't raise a TimeoutError if we reached the timeout and the future completed
in the same iteration of the event loop. A side effect of the bug is that
Queue.get() looses items.

* PipeServer.close() now cancels the "accept pipe" future which cancels the
overlapped operation.
* Fix _SelectorTransport.__repr__() if the transport was closed
* Fix debug log in BaseEventLoop.create_connection(): get the socket object
from the transport because SSL transport closes the old socket and creates a
new SSL socket object. Remove also the _SelectorSslTransport._rawsock
attribute: it contained the closed socket (not very useful) and it was not
used.
* Issue #22063: socket operations (sock_recv, sock_sendall, sock_connect,
sock_accept) of the proactor event loop don't raise an exception in debug
mode if the socket are in blocking mode. Overlapped operations also work on
blocking sockets.
* Fix unit tests in debug mode: mock a non-blocking socket for socket
operations which now raise an exception if the socket is blocking.
* _fatal_error() method of _UnixReadPipeTransport and _UnixWritePipeTransport
now log all exceptions in debug mode
* Don't log expected errors in unit tests
* Tulip issue 200: _WaitHandleFuture._unregister_wait() now catchs and logs
exceptions.
* Tulip issue 200: Log errors in debug mode instead of simply ignoring them.

* streams: drain() has no more a strange return value, it's just
a standard coroutine
