Title: change PyFile_AsFile signature to omit generated ref counting

The previous definition led cython to generate reference counting when
PyFile_AsFile() was called, like the below:

__pyx_t_1 = __pyx_v_self->_source;
__Pyx_INCREF(__pyx_t_1);
__pyx_v_c_stream = PyFile_AsFile(__pyx_t_1);
__Pyx_DECREF(__pyx_t_1); __pyx_t_1 = 0;

Modify its signature such that ref counting is not generated, which
should be the case (the function simply dereferences a member of the
file struct).
