cpython-lru_cache-weakref: Objects/funcobject.c annotate

annotate Objects/funcobject.c @ 19283:b865cd5c1925 legacy-trunk

Added comments before recently added/assigned slots in the type object, so the backward compatibility issues will be easier to understand. I only added comments indicating additions and assignments back to Python 2.0.
