asyncio: Close transports in tests
* Use test_utils.run_briefly() to execute pending calls to really close
transports
* sslproto: mock also _SSLPipe.shutdown(), it's need to close the transport
* pipe test: the test doesn't close explicitly the PipeHandle, so ignore
the warning instead
* test_popen: use the context manager ("with p:") to explicitly close pipes
Don't call immediatly self._process_write_backlog() but schedule the call using
call_soon(). _on_handshake_complete() can be called indirectly from
_process_write_backlog(), and _process_write_backlog() is not reentrant.

asyncio: sync with Tulip
* PipeHandle now uses None instead of -1 for a closed handle
* Sort imports in windows_utils.
* Fix test_events on Python older than 3.5. Skip SSL tests on the
ProactorEventLoop if ssl.MemoryIO is missing
* Fix BaseEventLoop._create_connection_transport(). Close the transport if the
creation of the transport (if the waiter) gets an exception.
* _ProactorBasePipeTransport now sets _sock to None when the transport is
closed.
* Fix BaseSubprocessTransport.close(). Ignore pipes for which the protocol is
not set yet (still equal to None).
* TestLoop.close() now calls the close() method of the parent class
(BaseEventLoop).
* Cleanup BaseSelectorEventLoop: create the protocol on a separated line for
readability and ease debugging.
* Fix BaseSubprocessTransport._kill_wait(). Set the _returncode attribute, so
close() doesn't try to terminate the process.
* Tests: explicitly close event loops and transports
* UNIX pipe transports: add closed/closing in repr(). Add "closed" or "closing"
state in the __repr__() method of _UnixReadPipeTransport and
_UnixWritePipeTransport classes.

"_Atomic void*" types work. Change needed on FreeBSD 10 where stdatomic.h is
available but the compiler fails on "_Atomic void*" with "_Atomic cannot be
applied to incomplete type 'void'".

Issue #22560: New SSL implementation based on ssl.MemoryBIO
The new SSL implementation is based on the new ssl.MemoryBIO which is only
available on Python 3.5. On Python 3.4 and older, the legacy SSL implementation
(using SSL_write, SSL_read, etc.) is used. The proactor event loop only
supports the new implementation.
The new asyncio.sslproto module adds _SSLPipe, SSLProtocol and
_SSLProtocolTransport classes. _SSLPipe allows to "wrap" or "unwrap" a socket
(switch between cleartext and SSL/TLS).
Patch written by Antoine Pitrou. sslproto.py is based on gruvi/ssl.py of the
gruvi project written by Geert Jansen.
This change adds SSL support to ProactorEventLoop on Python 3.5 and newer!
It becomes also possible to implement STARTTTLS: switch a cleartext socket to
SSL.

options for choosing default semantics to one and in the most
