bpo-45459: Add Py_buffer to limited API by tiran · Pull Request #29991 · python/cpython

This change broke our project build because when cpython/object.h is including buffer.h it is forcing it to resolve along the search path, and the compiler is hitting the buffer.h in our project rather than the one in the Python include directory.

Should it not be using a relative include, ie. #include "../buffer.h" ? I think otherwise this change will cause breakage for many projects given how common the header name "buffer.h" may be.
