[issue21233] Add *Calloc functions to CPython memory allocation API

[Julian Taylor]

Julian Taylor added the comment:

won't replacing _PyObject_GC_Malloc with a calloc cause Var objects (PyObject_NewVar) to be completely zeroed which I think they didn't before?
Some numeric programs stuff a lot of data into var objects and could care about python suddenly setting them to zero when they don't need it.
An example would be tinyarray.
