asyncio.BaseEventLoop now use the identifier of the current thread to ensure
that they are called from the thread running the event loop.

Before, the get_event_loop() method was used to check the thread, and no
exception was raised when the thread had no event loop. Now the methods always
raise an exception in debug mode when called from the wrong thread. It should
help to notice misusage of the API.

* Fix pyflakes warnings: remove unused imports and variables
* asyncio.test_support now uses test.support and test.script_helper if available

instead of reading /dev/urandom, to get pseudo-random bytes.

* Fix a race condition in BaseSubprocessTransport._try_finish().

  If the process exited before the _post_init() method was called, scheduling
  the call to _call_connection_lost() with call_soon() is wrong:
  connection_made() must be called before connection_lost().

  Reuse the BaseSubprocessTransport._call() method to schedule the call to
  _call_connection_lost() to ensure that connection_made() and
  connection_lost() are called in the correct order.

* Add repr(PipeHandle)

* Fix typo
