I commited current_handle.patch. It's only a first step, I will also change

I think it's OK to have something like `loop._current_handle` to work ~only~ in
debug mode. Enhancing `loop.call_exception_handler` to use it also
New submission from STINNER Victor:
One pain point of asynchronous programming is to understand bugs and rebuild
the chain of callbacks / coroutines / tasks. I added the source traceback to
Handle, Future (Task) and CoroWrapper to help debugging.
Here is a new enhancement to provide more
STINNER Victor added the comment:
Yury Selivanov proposed something different in the past: add a context (or a
