[issue26081] Implement asyncio Future in C to improve performance

[Yury Selivanov]

New submission from Yury Selivanov:

Some info on this: https://github.com/python/asyncio/issues/282#issuecomment-155957235  Long story short, Future implemented in C can speedup some asyncio code up to 25%.

I'm attaching a patch with a WIP implementation.  There are some failing assertions deep in GC, which I need to track down.  'Future.remove_done_callback' still needs to be properly implemented.
