Disable compiler optimization within test_peg_generator.
This speed up test_peg_generator by always disabling compiler
optimizations by using -O0 or equivalent when the test is building its
own C extensions.
A build not using --with-pydebug in order to speed up test execution
winds up with this test taking a very long time as it would do
repeated compilation of parser C code using the same optimization
flags as CPython was built with.
This speeds the test up 6-8x on gps-raspbian.
Also incorporate's #31017's win32 conditional and flags.

* Revert "bpo-45173 Remove configparser deprecations"
This reverts commit df2284bc41.
* bpo-45173: Note these configparser deprecations will be removed in 3.12
Per Pitrou:
> The original intent for the “accessor” thing was to have a variant that did all accesses under a filesystem tree in a race condition-free way using openat and friends. It turned out to be much too hairy to actually implement, so was entirely abandoned, but the accessor abstraction was left there.
https://discuss.python.org/t/make-pathlib-extensible/3428/2
Accessors are:
- Lacking any internal purpose - '_NormalAccessor' is the only implementation
- Lacking any firm conceptual difference to `Path` objects themselves (inc. subclasses)
- Non-public, i.e. underscore prefixed - '_Accessor' and '_NormalAccessor'
- Unofficially used to implement customized `Path` objects, but once once [bpo-24132]() is addressed there will be a supported route for that.
This patch preserves all existing behaviour.
The heredoc creation statements use >> to append conftest.c. This can cause
tricky build issues if the file is not correctly removed prior to its
name being reused (such name is reused several times for different
contextual tests during the build). One such result from appending may
cause #include <ac_nonexistent.h> to persist when testing to acquire
PLATFORM_TRIPLET. This can then lead to downstream issues concerning SOABI.
@pablogsal, sorry i failed to rebase to main, so i recreated https://github.com/python/cpython/pull/22190#issuecomment-1024633392
> PyRun_InteractiveOne\*() functions allow to explicitily set fd instead of stdin.
but stdin was hardcoded in readline call.
> This patch does not fix target file for prompt unlike original bpo one : prompt fd is unrelated to tokenizer source which could be read only. It is more of a bugfix regarding the docs : actual documentation say "prompt the user" so one would expect prompt to go on stdout not a file for both PyRun_InteractiveOne\*() and PyRun_InteractiveLoop\*().

Fix test_gdb.test_pycfunction() for Python built with clang -Og.
Tolerate inlined functions in the gdb traceback.
When _testcapimodule.c is built by clang -Og, _null_to_none() is
inlined in meth_varargs() and so gdb returns _null_to_none() as
the frame #1. If it's not inlined, meth_varargs() is the frame #1.
* bpo-46542: test_lib2to3 uses support.infinite_recursion()
Fix a Python crash in test_lib2to3 when using Python built in debug
mode: limit the recursion limit.
The test_all_project_files() test of test_lib2to3 now uses the
test.support.infinite_recursion() context manager when processing the
infinite_recursion.py file to prevent a crash when Python is built in
debug mode.
The two test_all_project_files() tests now use subTest() and log the
refactored/parsed filename (if test_lib2to3 is run in verbose mode).
* Update Lib/lib2to3/tests/data/infinite_recursion.py

musl libc and gnu libc are not ABI compatible so we need set different
SOABI for musl and not simply assume that all linux is linux-gnu.
Replace linux-gnu with the detected os for the build from config.guess
for linux-musl*.
* Add PRECALL_FUNCTION opcode.
* Move 'call shape' varaibles into struct.
* Replace CALL_NO_KW and CALL_KW with KW_NAMES and CALL instructions.
* Specialize for builtin methods taking using the METH_FASTCALL | METH_KEYWORDS protocol.
* Allow kwnames for specialized calls to builtin types.
* Specialize calls to tuple(arg) and str(arg).
Added new internal functions to compute mod without also computing the quotient.
The loops can be leaner then, which leads to modestly but reliably faster execution in contexts that know they don't need the quotient.
Code by Jeremiah Vivian (Pascual).
Remove the PyHeapType_GET_MEMBERS() macro. It was exposed in the
public C API by mistake, it must only be used by Python internally.
Use the PyTypeObject.tp_members member instead.
Rename PyHeapType_GET_MEMBERS() to _PyHeapType_GET_MEMBERS() and move
it to the internal C API.
* Substitution with a list of types returns now a tuple of types.
* Substitution with Concatenate returns now a Concatenate with
concatenated lists of arguments.
* Substitution with Ellipsis is not supported.
Revert "bpo-45162: Remove many old deprecated unittest features (GH-28268)"
This reverts commit b0a6ede3d0.
We're deferring this change until 3.12 while upstream projects that use
the legacy assertion method names are fixed. See the issue for links
to the discussion. Many upstream projects now have issues and PRs
filed.
In the File menu, 'Close' and 'Exit' are now 'Close Window' (the current
one) and 'Exit' is now 'Exit IDLE' (by closing all windows).
In Shell, 'quit()' and 'exit()' mean 'close Shell'.
If there are no other windows, this also exits IDLE.
Previously this didn't matter because there weren't any valid code paths
that could trigger a type check with a special form, but after the bug
fix for `Annotated` wrapping special forms it's now possible to annotate
something like `Annotated['ClassVar[int]', (3, 4)]`. This change would
also be needed for proposed future changes, such as allowing `ClassVar`
and `Final` to nest each other in dataclasses.
We treat Annotated type arg as class-level annotation. This exempts it from checks against Final and ClassVar in order to allow using them in any nesting order.

When configuring the logging stack, accept already built filters (or
just callables) in the filters array of loggers and handlers.
This facilitates passing quick callables as filters.
