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.

It did not work in the case of a subpattern containing backtracking.
Temporary implement possessive quantifiers as equivalent greedy qualifiers
in atomic groups.
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.
Cover all the Mapping Protocol, almost all the Sequence Protocol
(except PySequence_Fast) and a part of the Object Protocol.
Move existing tests to Lib/test/test_capi/test_abstract.py and
Modules/_testcapi/abstract.c.
Add also tests for PyDict C API.
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.
It is now possible to deprecate passing parameters positionally with
Argument Clinic, using the new '* [from X.Y]' syntax.
(To be read as "keyword-only from Python version X.Y")

Introducing a new file, stacking.py, that takes over several responsibilities related to symbolic evaluation of push/pop operations, with more generality.
- always wrap the offending line, token, or name in quotes
- in most cases, put the entire error message on one line
Added tests for uncovered branches that were touched by this PR.

Introduce ClinicError, and use it in fail(). The CLI runs main(),
catches ClinicError, formats the error message, prints to stderr
and exits with an error.
As a side effect, this refactor greatly improves the accuracy of
reported line numbers in case of error.
Also, adapt the test suite to work with ClinicError.

gh-107184 introduced a refleak in test_import.SubinterpImportTests (specifically test_singlephase_check_with_setting_and_override and test_single_init_extension_compat). We fix it here by making sure _testsinglephase is removed from sys.modules whenever we clear the runtime's internal state for the module.
The underlying problem is strictly contained in the internal function _PyImport_ClearExtension() (AKA _testinternalcapi.clear_extension()), which is only used in tests.
(This also fixes an intermittent segfault introduced in the same place, in test_disallowed_reimport.)
Previously, only function docstrings were checked for non-ASCII characters.
Also, improve the warn() message.

Introduce docstring_append() helper, and use it for both parameter and
function docstrings. Remove docstring fixup from
do_post_block_processing_cleanup(); instead, make sure no fixup is needed.

- Use ArgumentParser.error() to handle CLI errors
- Put the entire CLI in main()
- Rework ClinicExternalTest to call main() instead of using subprocesses

Represent IPv4-mapped IPv6 address as x❌x❌x❌d.d.d.d,
where the 'x's are the hexadecimal values
of the six high-order 16-bit pieces of the address,
and the 'd's are the decimal values
of the four low-order 8-bit pieces of the address
(standard IPv4 representation).

We tried this before with a dict and for all interned strings. That ran into problems due to interpreter isolation. However, exclusively using a per-interpreter cache caused some inconsistency that can eliminate the benefit of interning. Here we circle back to using a global cache, but only for statically allocated strings. We also use a more-basic _Py_hashtable_t for that global cache instead of a dict.
Ideally we would only have the global cache, but the optional isolation of each interpreter's allocator means that a non-static string object must not outlive its interpreter. Thus we would have to store a copy of each such interned string in the global cache, tied to the main interpreter.
The two tests are crashing periodically in CI and on buildbots. I suspect the problem is in the _xxsubinterpreters module.
Regardless, I'm disabling the tests temporarily, to reduce the noise as we approach 3.12rc1. I'll be investigating the crashes separately.
Adding the `rtype_cache` to the `warnings.warn` message improves the
previous, somewhat vague message from
```
/Users/username/cpython/Lib/multiprocessing/resource_tracker.py:224: UserWarning: resource_tracker: There appear to be 6 leaked semaphore objects to clean up at shutdown
```
to

test_logging: Fix test_udp_reconnection() by increasing the timeout
from 100 ms to 5 minutes (LONG_TIMEOUT).
Replace also blocking wait() with wait(LONG_TIMEOUT) in
test_output() to prevent the test to hang.
Instead of hacking into the Clinic class, use the Argument Clinic tool
to run the ClinicExternalTest test suite.

Move private _PyMem functions to the internal C API (pycore_pymem.h):
* _PyMem_GetCurrentAllocatorName()
* _PyMem_RawStrdup()
* _PyMem_RawWcsdup()
* _PyMem_Strdup()
No longer export these functions.
Move pymem_getallocatorsname() function from _testcapi to _testinternalcapi,
since the API moved to the internal C API.
This mostly extracts a whole bunch of stuff out of generate_cases.py into separate files, but there are a few other things going on here.
- analysis.py: `Analyzer` etc.
- instructions.py: `Instruction` etc.
- flags.py: `InstructionFlags`, `variable_used`, `variable_used_unspecialized`
- formatting.py: `Formatter` etc.
- Rename parser.py to parsing.py, to avoid conflict with stdlib parser.py
- Blackify most things
- Fix most mypy errors
- Remove output filenames from Generator state, add them to `write_instructions()` etc.
- Fix unit tests
Move private debug _PyObject functions to the internal C API
(pycore_object.h):
* _PyDebugAllocatorStats()
* _PyObject_CheckConsistency()
* _PyObject_DebugTypeStats()
* _PyObject_IsFreed()
No longer export most of these functions, except of
_PyObject_IsFreed().
Move test functions using _PyObject_IsFreed() from _testcapi to
_testinternalcapi. check_pyobject_is_freed() test no longer catch
_testcapi.error: the tested function cannot raise _testcapi.error.
