ContextTask do not copy parents context about curio

[dabeaz]

Just to make sure that I understand this, the primary issue is that new tasks aren't created within the context of the parent task?

All things equal, I don't want the Curio core to be dependent on contextvars. However, it may be possible to restructure things slightly to make this possible. I will investigate.

Yes, indeed, the issue that the new tasks are created outside current context, so those tasks cant access the parent context.

I endup using this patch which does not incluide too much dependancies in the core, but still there are probably better ways to do this.

I made a modification to have the parent task passed to the Task.__init__() method. Let me know if this addresses the problem.
