Restore following CPython <= 3.10.5 behavior of shutil.make_archive()
that went away as part of gh-93160:
Do not create an empty archive if root_dir is not a directory, and, in
that case, raise FileNotFoundError or NotADirectoryError regardless
of format choice. Beyond the brought-back behavior, the function may
now also raise these exceptions in dry_run mode.

Attempt to speed up deepfreeze.py (#107887)
* Instead of calling get_identifiers_and_strings(), extract identifiers and strings from pycore_global_strings.h.
* Avoid ast.literal_eval(), it's very slow.

gh-106844: Fix issues in _winapi.LCMapStringEx (GH-107832)
* Strings with length from 2**31-1 to 2**32-2 always caused MemoryError,
it doesn't matter how much memory is available.
* Strings with length exactly 2**32-1 caused OSError.
* Strings longer than 2**32-1 characters were truncated due to integer overflow bug.
* Strings containing the null character were truncated at the first null character.
Now strings longer than 2**31-1 characters caused OverflowError and the null character is allowed.
gh-95065: Argument Clinic: Add functional tests of deprecated positionals (#107768)
Move the "deprecated positinal" tests from clinic.test.c to
_testclinic.c. Mock PY_VERSION_HEX in order to prevent generated
compiler warnings/errors to trigger. Put clinic code for deprecated
positionals in Modules/clinic/_testclinic_depr_star.c.h for easy
inspection of the generated code.

gh-107758: Improvements to lltrace feature (#107757)
- The `dump_stack()` method could call a `__repr__` method implemented in Python,
causing (infinite) recursion.
I rewrote it to only print out the values for some fundamental types (`int`, `str`, etc.);
for everything else it just prints `<type_name @ 0xdeadbeef>`.
- The lltrace-like feature for uops wrote to `stderr`, while the one in `ceval.c` writes to `stdout`;
I changed the uops to write to stdout as well.
- Generalize the syntax for the type of a stack effect to allow a trailing `*`,
so we can declare something as e.g. `PyCodeObject *`.
- When generating assignments for stack effects,
the type of the value on the stack should be the default (i.e., `PyObject *`)
even when the variable copied to/from it has a different type,
so that an appropriate cast is generated
However, not when the variable is an array --
then the type is taken from the variable (as it is always `PyObject **`).

gh-107630: Fix Remaining Subinterpreters Crashes on Py_TRACE_REFS Builds (gh-107750)
This is a follow-up to gh-107567 and gh-107733.
We skip test_basic_multiple_interpreters_deleted_no_reset on tracerefs builds. The test breaks interpreter isolation a little, which doesn't work well with Py_TRACE_REFS builds, so I feel fine about skipping the test.

gh-98154: Clarify Usage of "Reference Count" In the Docs (gh-107552)
PEP 683 (immortal objects) revealed some ways in which the Python documentation has been unnecessarily coupled to the implementation details of reference counts. In the end users should focus on reference ownership, including taking references and releasing them, rather than on how many reference counts an object has.
This change updates the documentation to reflect that perspective. It also updates the docs relative to immortal objects in a handful of places.
gh-107715: Escape class name in regular expression (GH-107716)
This patch escapes the class name before embedding it in the regular expression
for `pat` in `doctest.DocTestFinder._find_lineno`. While class names do not
ordinarily contain special characters, it is possible to encounter these when a
class is created dynamically. Escaping the name will correctly return `None` in
this scenario, rather than potentially matching a different class or raising
`re.error` depending on the symbols used.
