Zachary Ware a4b7a7548c Issue #3158: doctest can now find doctests in functions and methods
written in C.

As a part of this, a few doctests have been added to the builtins module
(on hex(), oct(), and bin()), a doctest has been fixed (hopefully on all
platforms) on float, and test_builtins now runs doctests in builtins.

Nick Coghlan 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.

Victor Stinner 8455723cfb Close #19568: Fix bytearray_setslice_linear(), fix handling of
PyByteArray_Resize() failure: leave the bytearray object in an consistent state.

If growth < 0, handling the memory allocation failure is tricky here because
the bytearray object has already been modified.  If lo != 0, the operation is
completed, but a MemoryError is still raised and the memory block is not
shrinked. If lo == 0, the bytearray is restored in its previous state and a
MemoryError is raised.

Nick Coghlan 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.

Serhiy Storchaka 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.

Victor Stinner 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

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