typedef int (*bucket_compare_func_t)(Bucket *a, Bucket *b);
Previously compare_func_t was used, which accepted void pointers.
Furthermore, the return type of zend_hash_sort and zend_ts_hash_sort has
been changed from int to void; these functions always succeed.
o. The cast_object() handler is now required, i.e. must be non-null. You can
indicate that casting is not supported by always returning FAILURE.
