3.10 compatability -- changes to frame object

[isidentical]

Due to the changes in python/cpython#20803 (made the code a lot simpler), yappi isn't compiling on 3.10;

 $ python -m pip install yappi

Thanks for the heads up! Working on it.

[sumerc]

I have a probable fix for this. @isidentical , I was using f_stacktop being non-NULL to detect a coroutine yield now I use frame->state == FRAME_SUSPENDED. All tests pass on my side. Can you spot any issue with that?

See the possible fix: https://github.com/sumerc/yappi/pull/66

Yeah, looks right!
