Convert macros to static inline functions to avoid macro pitfalls, like duplication of side effects: * DK_ENTRIES() * DK_UNICODE_ENTRIES() * PyCode_GetNumFree() * PyFloat_AS_DOUBLE() * PyInstanceMethod_GET_FUNCTION() * PyMemoryView_GET_BASE() * PyMemoryView_GET_BUFFER() * PyMethod_GET_FUNCTION() * PyMethod_GET_SELF() * PySet_GET_SIZE() * _PyHeapType_GET_MEMBERS() Changes: * PyCode_GetNumFree() casts PyCode_GetNumFree.co_nfreevars from int to Py_ssize_t to be future proof, and because Py_ssize_t is commonly used in the C API. * PyCode_GetNumFree() doesn't cast its argument: the replaced macro already required the exact type PyCodeObject*. * Add assertions in some functions using "CAST" macros to check the arguments type when Python is built with assertions (debug build). * Remove an outdated comment in unicodeobject.h.
