[New-bugs-announce] [issue28504] Cleanup unicode_decode_call_errorhandler_wchar/writer

[Xiang Zhang]

New submission from Xiang Zhang:

The patch makes several cleanups to unicode_decode_call_errorhandler_wchar/writer:

1. Use U instead O! for argument parser, it ought to be more efficient and write less code.
2. In theory, if inputobj is not bytes, there needs to be a goto onError, or it could crash. But PyUnicodeDecodeError_GetObject is guaranteed to return bytes, so we can remove the incomplete branch.
3. On success, we don't need Xdecref.
