Log: Explicitly use Py_ssize_t as the Signed type in pypy c-api.
The signature for the c-api uses Py_ssize_t for the unsigned
arguments. `long` is equivalent to `Py_ssize_t` (in fact
`Py_ssize_t` is a `typedef` of `long`) in all cases in C, but when
integrating with go, `C.long` and `C.Py_ssize_t` are considered two
disparate incompatible types. By using `Py_ssize_t` in the function
signature, pypy + cpython compatible code can be written.
