Always create the empty bytes string singleton. Optimize PyBytes_FromStringAndSize(str, 0): it no longer has to check if the empty string singleton was created or not, it is always available. Add functions: * _PyBytes_Init() * bytes_get_empty(), bytes_new_empty() * bytes_create_empty_string_singleton() * unicode_create_empty_string_singleton() * _Py_unicode_state: rename empty member to empty_string
