gh-139156: Use PyBytesWriter in _PyUnicode_EncodeCharmap() (#139251) 
Replace PyBytes_FromStringAndSize() and _PyBytes_Resize() with the
PyBytesWriter API.

Add _PyBytesWriter_GetSize() and _PyBytesWriter_GetData() static
inline functions.

gh-133767: Fix use-after-free in the unicode-escape decoder with an error handler (GH-129648) 
If the error handler is used, a new bytes object is created to set as
the object attribute of UnicodeDecodeError, and that bytes object then
replaces the original data. A pointer to the decoded data will became invalid
after destroying that temporary bytes object. So we need other way to return
the first invalid escape from _PyUnicode_DecodeUnicodeEscapeInternal().

_PyBytes_DecodeEscape() does not have such issue, because it does not
use the error handlers registry, but it should be changed for compatibility
with _PyUnicode_DecodeUnicodeEscapeInternal().

Remove almost all unpaired backticks in docstrings (#119231) 
As reported in #117847 and #115366, an unpaired backtick in a docstring
tends to confuse e.g. Sphinx running on subclasses of standard library
objects, and the typographic style of using a backtick as an opening
quote is no longer in favor. Convert almost all uses of the form

    The variable `foo' should do xyz

to

    The variable 'foo' should do xyz

and also fix up miscellaneous other unpaired backticks (extraneous /
missing characters).

No functional change is intended here other than in human-readable
docstrings.

gh-117431: Adapt bytes and bytearray .find() and friends to Argument Clinic (#117502) 
This change gives a significant speedup, as the METH_FASTCALL calling
convention is now used. The following bytes and bytearray methods are adapted:

- count()
- find()
- index()
- rfind()
- rindex()

gh-108767: Replace ctype.h functions with pyctype.h functions (#108772) 
Replace <ctype.h> locale dependent functions with Python "pyctype.h"
locale independent functions:

* Replace isalpha() with Py_ISALPHA().
* Replace isdigit() with Py_ISDIGIT().
* Replace isxdigit() with Py_ISXDIGIT().
* Replace tolower() with Py_TOLOWER().

Leave Modules/_sre/sre.c unchanged, it uses locale dependent
functions on purpose.

Include explicitly <ctype.h> in _decimal.c to get isascii().
