c72e4e6dcc Issue #19619: Blacklist non-text codecs in method API 
str.encode, bytes.decode and bytearray.decode now use an
internal API to throw LookupError for known non-text encodings,
rather than attempting the encoding or decoding operation and
then throwing a TypeError for an unexpected output type.

The latter mechanism remains in place for third party non-text
encodings.

a5bcd7c0ee Issue #19183: too many tests depend on the sort order of repr(). 
The bitshift and xor op for 32bit builds has changed the order of hash values.

85fe8a645e Issue #9566, #19617: New try to fix compilation on Windows

instead of an signed integer.

ad9a066050 Issue #9566: compile.c uses Py_ssize_t instead of int to store sizes to fix 
compiler warnings on Windows 64-bit. Use Py_SAFE_DOWNCAST() where the final
downcast is needed.

The bytecode doesn't support integer parameters larger than 32-bit yet.

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

efa7a0e155 print_error_text() doesn't encode the filename anymore 
Use aslo PyUnicode_FromFormat() to format the line so only one call to
PyFile_WriteObject() is needed. tb_displayline() of Python/traceback.c has
similar implementation.
