pythongh-95778: CVE-2020-10735: Prevent DoS by very large int() (pythonGH-96504)

Converting between `int` and `str` in bases other than 2
(binary), 4, 8 (octal), 16 (hexadecimal), or 32 such as base 10 (decimal) now
raises a `ValueError` if the number of digits in string form is above a
limit to avoid potential denial of service attacks due to the algorithmic
complexity. This is a mitigation for CVE-2020-10735
(https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10735).

This new limit can be configured or disabled by environment variable, command
line flag, or :mod:`sys` APIs. See the `Integer String Conversion Length
Limitation` documentation.  The default limit is 4300
digits in string form.

Patch by Gregory P. Smith [Google] and Christian Heimes [Red Hat] with feedback
from Victor Stinner, Thomas Wouters, Steve Dower, Ned Deily, and Mark Dickinson.

Notes on the backport to Python 3.6:

* Use "Python 3.6.15-13" version in the documentation, whereas this
  version will never be released
* Only add _Py_global_config_int_max_str_digits global variable:
  Python 3.6 doesn't have PyConfig API (PEP 597) nor _PyRuntime.
* sys.flags.int_max_str_digits cannot be -1 on Python 3.6: it is
  set to the default limit. Adapt test_int_max_str_digits() for that.
* Declare _PY_LONG_DEFAULT_MAX_STR_DIGITS and
  _PY_LONG_MAX_STR_DIGITS_THRESHOLD macros in longobject.h but only
  if the Py_BUILD_CORE macro is defined.
* Declare _Py_global_config_int_max_str_digits in pydebug.h.
