Andrew Svetlov 68b34a7204 bpo-36921: Deprecate @coroutine for sake of async def (GH-13346)
The second attempt. Now deprecate `@coroutine` only, keep `yield from fut` as is.

asyncio: Remove asyncio/compat.py (#4606)
The asyncio/compat.py file was written to support Python < 3.5 and
Python < 3.5.2. But Python 3.5 doesn't accept bugfixes anymore, only
security fixes. There is no more need to backport bugfixes to Python
3.5, and so no need to have a single code base for Python 3.5, 3.6
and 3.7.

Say hello (again) to "async" and "await", who became real keywords in
Python 3.7 ;-)

Yury Selivanov 6cc495e9e2 asyncio: Fix _format_coroutine for coroutine-like objects w/o __name__
Some built-in coroutine-like objects might not have __name__ or
__qualname__. A good example of such are 'asend', 'aclose' and
'athrow' coroutine methods of asynchronous generators.

Yury Selivanov a0c1ba608e Issue #28544: Implement asyncio.Task in C.
This implementation provides additional 10-20% speed boost for
asyncio programs.

The patch also fixes _asynciomodule.c to use Arguments Clinic, and
makes '_schedule_callbacks' an overridable method (as it was in 3.5).

Victor Stinner c39ba7d611 asyncio: sync with Tulip
- repr(Task) and repr(CoroWrapper) now also includes where these objects were
  created. If the coroutine is not a generator (don't use "yield from"), use
  the location of the function, not the location of the coro() wrapper.
- Fix create_task(): truncate the traceback to hide the call to create_task().

  KeyboardInterrupt or the coroutine objet is destroyed lately, some the
  _source_traceback attribute doesn't exist anymore.
* repr(Task): include also the future the task is waiting for

- Sort imports
- Simplify/optimize iscoroutine(). Inline inspect.isgenerator(obj): replace it

- CoroWrapper: check at runtime if Python has the yield-from bug #21209.  If
  Python has the bug, check if CoroWrapper.send() was called by yield-from to
  decide if parameters must be unpacked or not.
- Fix "Task was destroyed but it is pending!" warning in
