ctypes.CFUNCTYPE() and ctypes.WINFUNCTYPE() now fail to create the
type if its "_argtypes_" member contains too many arguments.
Previously, the error was only raised when calling a function.
Change also how CFUNCTYPE() and WINFUNCTYPE() handle KeyError to
prevent creating a chain of exceptions if ctypes.CFuncPtr raises an
error.
bytesobject.c, bytearrayobject.c and unicodeobject.c now define all
macros used by stringlib, to avoid using undefined macros.
Fix "gcc -Wundef" warnings.
skip_if_buggy_ucrt_strfptime() of test.support now uses
locale.getpreferredencoding(False) instead of
locale.getdefaultlocale() to get the Windows code page.
encodings registers the _alias_mbcs() codec search function before
the search_function() codec search function. Previously, the
_alias_mbcs() was never used.
Fix the test_codecs.test_mbcs_alias() test: use the current ANSI code
page, not a fake ANSI code page number.
Remove the test_site.test_aliasing_mbcs() test: the alias is now
implemented in the encodings module, no longer in the site module.
Building Python now requires a C99 <math.h> header file providing a
NAN constant, or the __builtin_nan() built-in function. If a platform
does not support Not-a-Number (NaN), the Py_NO_NAN macro can be
defined in the pyconfig.h file.

This reduces the size of the data segment by **300 KB** of the executable because if the modules are deep-frozen then the marshalled frozen data just wastes space. This was inspired by comment by @gvanrossum in https://github.com/python/cpython/pull/29118#issuecomment-958521863. Note: There is a new option `--deepfreeze-only` in `freeze_modules.py` to change this behavior, it is on be default to save disk space.

It was added as part of #29222 to avoid running freeze tool tests on the
buildbots but the logic was wrong so it did not skip tests on typical posix
setup buildbots where the worker is launched from cron via an @reboot task and
thus have no USER environment variable. This uses the canonical
`getpass.getuser()` API rather than rolling its own attempt.
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.
