As discussed several times before we need to convert `@coroutine` / `yield from` to async/await.

All existing functionality should keep working (like yielding from new style coroutine and `with (yield from lock)`.

We could deprecate the later though.

The change should be huge but there is no alternative, keeping `yield from` in stdlib looks uglier and uglier every year.

Unittests should be changed as well (keeping several `yield from` for checking backward compatibility is Ok).

Yeah, I am in favor of this. How will we guarantee that clients using the old `@coroutine`/`yield from` idiom still work? We need to have separate tests for that.

They are fully supported now, but we can add a few tests to ensure we won't break it.
