See: capi-workgroup/decisions#108

I'm aware this change doesn't follow the "regular" style of header pairs in Include and Include/cpython, but it looks like Include/cpython/classobject.h was meant to be #includeable as a header directly, rather than only via Include/classobject.h indirectly, so I kept that for backwards compatibility.

As a result, PyMethod_New is declared twice, which is not an issue (divergence would be caught by the compiler), but slightly suboptimal. I didn't immediately see a way to make this work, though (except for having Include/cpython/classobject.h include Include/classobject.h, which seems undesirable).

Include: change guard of cpython/classobject.h
f879f0d 
This aligns it more with other headers in `cpython/` and frees up
the guard for `Include/classobject.h`.
