f2e1768bc1 Issue #20455: asyncio: use the same code to round a timeout than the selectors 
module

Sort also imports

b60e9ca69d Issue #20455: asyncio: write a new write pipe transport class for proactor (on 
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.

8dffc456d7 Update asyncio from the Tulip project 
Major changes:

- StreamReader.readexactly() now raises an IncompleteReadError if the
  end of stream is reached before we received enough bytes, instead of
  returning less bytes than requested.

- Unit tests use the main asyncio module instead of submodules like events

- _UnixWritePipeTransport now also supports character devices, as
  _UnixReadPipeTransport. Patch written by Jonathan Slenders.

- Export more symbols: BaseEventLoop, BaseProactorEventLoop,
  BaseSelectorEventLoop, Queue and Queue sublasses, Empty, Full

f67255ab94 Issue #20311: asyncio: Add a granularity attribute to BaseEventLoop: maximum 
between the resolution of the BaseEventLoop.time() method and the resolution of
the selector. The granuarility is used in the scheduler to round time and
deadline.

4a2dbeb0d3 asyncio: Cleanup logging in BaseEventLoop._run_once() 
logger.log() is now responsible to format the timeout. It might be faster if
the log is disabled for DEBUG level, but it's also more readable and fix
an issue with Python 2.6 in the Trollius project.

22463aa947 Close #20275: Optimize BaseEventLoop._run_once() 
Logger.log() is "slow", logger.isEnabledFor() is faster and the logger is
disabled in most cases. A microbenchmark executing 100,000 dummy tasks is 22%
faster with this change.

7de2646cdf Cleanup properly proactor event loop 
* store the "self reading" future when the "self pipe" is closed (when the
  event loop is closed)
* store "accept" futures to cancel them when we stop serving
* close the "accept socket" if the "accept future" is cancelled

Fix many warnings which can be seen when unit tests are run in verbose mode.
