Fix double-free bug mentioned at GH-99240, by moving memory clean up out of "exit" label.
It affects function os.system() on Windows and Windows-specific modules
winreg, _winapi, _overlapped, and _msi.
(cherry picked from commit 0ee9619a4cba58730c45e65d22288fadbf7680de)
Fix a shell code injection vulnerability in the
get-remote-certificate.py example script. The script no longer uses a
shell to run "openssl" commands. Issue reported and initial fix by
Caleb Shortt.
Remove the Windows code path to send "quit" on stdin to the "openssl
s_client" command: use DEVNULL on all platforms instead.

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 GH-31017's win32 conditional and flags.

"make regen-all" now produces the same output when run from a
directory other than the source tree: when building Python out of the
source tree.

There are two errors that this commit fixes:
* The parser was not correctly computing the offset and the string
source for E_LINECONT errors due to the incorrect usage of strtok().
* The parser was not correctly unwinding the call stack when a tokenizer
exception happened in rules involving optionals ('?', [...]) as we
always make them return valid results by using the comma operator. We
need to check first if we don't have an error before continuing..

* Remove struct _node from the stable ABI list
This struct was removed along with the old parser in Python 3.9 (PEP 617)
* Stable ABI list: Use the public name "PyFrameObject" rather than "_frame"
* Ensure limited API doesn't contain private names
Names prefixed by an underscore are private by definition.
* Add a blurb

The invalid assignment rules are very delicate since the parser can
easily raise an invalid assignment when a keyword argument is provided.
As they are very deep into the grammar tree, is very difficult to
specify in which contexts these rules can be used and in which don't.
For that, we need to use a different version of the rule that doesn't do
error checking in those situations where we don't want the rule to raise
(keyword arguments and generator expressions).
We also need to check if we are in left-recursive rule, as those can try
to eagerly advance the parser even if the parse will fail at the end of
the expression. Failing to do this allows the parser to start parsing a
call as a tuple and incorrectly identify a keyword argument as an
invalid assignment, before it realizes that it was not a tuple after all.
