f1de55fb33 Also chain codec exceptions that allow weakrefs 
The zlib and hex codecs throw custom exception types with
weakref support if the input type is valid, but the data
fails validation. Make sure the exception chaining in the
codec infrastructure can wrap those as well.

58cf607d13 Issue #12892: The utf-16* and utf-32* codecs now reject (lone) surrogates. 
The utf-16* and utf-32* encoders no longer allow surrogate code points
(U+D800-U+DFFF) to be encoded.
The utf-32* decoders no longer decode byte sequences that correspond to
surrogate code points.
The surrogatepass error handler now works with the utf-16* and utf-32* codecs.

Based on patches by Victor Stinner and Kang-Hao (Kenny) Lu.

8b097b4ed7 Close #17828: better handling of codec errors 
- output type errors now redirect users to the type-neutral
  convenience functions in the codecs module
- stateless errors that occur during encoding and decoding
  will now be automatically wrapped in exceptions that give
  the name of the codec involved

fa3ba4c3bc Issue #18609: Add a fast-path for "iso8859-1" encoding 
On AIX, the locale encoding may be "iso8859-1", which was not a known syntax of
the legacy ISO 8859-1 encoding.

Using a C codec instead of a Python codec is faster but also avoids tricky
issues during Python startup or complex code.
