Remove unneeded dummy test from the set search loop (when the hashes match we know the key is not a dummy).

Instead of masking and shifting every loopup, move the wrap-around
test outside of the inner-loop.

There was a bug which was fixed. The unit test was also wrong.

If ReadFile() fails with ERROR_BROKEN_PIPE, the operation is not pending: don't
register the overlapped.

I don't know if WSARecv() can fail with ERROR_BROKEN_PIPE. Since
Overlapped.WSARecv() already handled ERROR_BROKEN_PIPE, let me guess that it
has the same behaviour than ReadFile().

If UnregisterWaitEx() fais with ERROR_IO_PENDING, it doesn't mean that the wait
is unregistered yet. We still have to wait until the wait is cancelled.

Explicitly cast the long to char.

PyUnicode_EncodeCodePage() now raise an exception if the object is not an
Unicode object. For PyUnicode_EncodeFSDefault(), it was already the case on
platforms other than Windows. Patch written by Campbell Barton.

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().

If a client connected before the server was closed: drop the client (close the
pipe) and exit.

In debug mode, BaseEventLoop._run_once() now sets the
BaseEventLoop._current_handle attribute to the handle currently executed.
In release mode or when no handle is executed, the attribute is None.

BaseEventLoop.default_exception_handler() displays the traceback of the current
handle if available.

The special case for connect_pipe() is not more needed. connect_pipe() doesn't
use overlapped operations anymore.

Fix create_datagram_endpoint(), connect_read_pipe() and connect_write_pipe():
close the transport if the task is cancelled or on error.
