The library .so file is named pypy3-c rather than pypy-c.

CPython extensions built for PyPy should be named used a special suffix
which includes the variant of Python e.g. .pypy-41.so. These can be
loaded at runtime (import module) without doing anything special and
will not be confused with regular Python CPython modules.

This call does not exist in PyPy (as it presumably doesn't refcount).

This type is unavailable in PyPy (and also unlikely to be exposed). This
just removes a type-check.
