Revert r81171 (posix_listdir(), posix_readlink(): avoid temporary PyBytes object)
PyUnicode_DecodeFSDefault*() doesn't use surrogateescape error handler, and so PyUnicode_FromEncodedObject(v, Py_FileSystemDefaultEncoding, "surrogateescape") cannot be replaced by PyUnicode_DecodeFSDefault(). It's a bad idea to try to fix surrogates things in Python 3.1...
