Windows) instead of using the "duplex" pipe transport. The new class uses a
simpler overlapped read to be notified when the pipe is closed. So the protocol
doesn't need to implement eof_received(): connection_lost() is called instead.
_UnixWritePipeTransport has the same approach.

instead of rounding towards zero, in select and selectors modules:
select.epoll.poll(), selectors.PollSelector.poll() and
selectors.EpollSelector.poll(). For example, a timeout of one microsecond
(1e-6) is now rounded to one millisecondi (1e-3), instead of being rounded to
zero.

Mention the change in Misc/NEWS.

Mention that wait_for() now accepts None for the timeout.

Moreover, bufsize different than 0 is now considered as an error.

asyncio: Pass through pause/resume from subprocess pipe proto to subprocess proto. Also kill dummy eof_received().

asyncio: _fatal_error() of _UnixWritePipeTransport and _ProactorBasePipeTransport shouldn't log BrokenPipeError nor ConnectionResetError.
