Add support for tvOS, visionOS and watchOS. This is mostly configuration
updates and testbed projects to support deploying to the new platforms.
Also includes a mimalloc change to support arm64_32 that has been contributed
upstream.
Add constants decimal.LIBMPDEC_VERSION, decimal.libmpdec_version,
decimal.LIBMPDEC_VERSION_INFO, and decimal.libmpdec_version_info in
the C implementation, which provide information about the version of
the libmpdec library in use.

Add constants which provide information about the version of the
underlying library in use: GDBM_VERSION_INFO, gdbm_version_info and
gdbm_version if it is GDBM, or BDB_VERSION, bdb_version,
BDB_VERSION_INFO and bdb_version_info if it is Berkeley DB.
dbm.ndbm.library is now 'ndbm' instead of 'GNU gdbm' for a classic
NDBM library.

named tuples with the versions of the Tcl and Tk libraries that were
used for building the module, and _tkinter.TCL_PATCH_LEVEL and
_tkinter.TK_PATCH_LEVEL strings.

ssl.OPENSSL_VERSION_INFO is now a named tuple.
Add ssl.OPENSSL_API_VERSION_INFO which provides information about the
version of the OpenSSL library that was used for building the module.
The private name _OPENSSL_API_VERSION is kept as an alias.

Add constants readline.READLINE_VERSION_INFO,
readline.readline_version_info and readline.readline_version, which
provide information about the version of the Readline library in use.
The private names _READLINE_VERSION, _READLINE_RUNTIME_VERSION and
_READLINE_LIBRARY_VERSION are kept for backward compatibility.

Add constants dbm.gnu.GDBM_VERSION_INFO, dbm.gnu.gdbm_version_info and
dbm.gnu.gdbm_version, which provide information about the version of
the GDBM library in use.
The private constant _gdbm._GDBM_VERSION has been removed.

* test_cext now uses a single virtual environment for all tests.
It makes the test way faster since creating a virtual environment
is quite slow.
* Add Py_TARGET_ABI3T test on C++.
* Move macro tests from module exec function to test_macros().
* Call Py_BEGIN_CRITICAL_SECTION() on a fresh dictionary object,
rather than on the module.
* Rename some environment variables to always use "CPYTHON_TEST_"
prefix.
* Replace support.MS_WINDOWS with MSVC to be more explicit.
* Move macro tests to test_macros().
* On macOS, use C++11 by default.
Add constants ctypes.LIBFFI_VERSION, ctypes.libffi_version,
ctypes.LIBFFI_VERSION_INFO and ctypes.libffi_version_info, which
provide information about the version of the libffi library in use.
They are only available with libffi 3.5 or later.

Add constants which provide information about the version of the
compression library used for building the module and the version
actually loaded:
* zlib: ZLIB_VERSION_INFO, zlib_version_info, ZLIBNG_VERSION_INFO,
and zlib_version as an alias of ZLIB_RUNTIME_VERSION
* bz2: bzlib_version, bzlib_version_info
* lzma: LZMA_VERSION, lzma_version, LZMA_VERSION_INFO, lzma_version_info
* compression.zstd: ZSTD_VERSION, ZSTD_VERSION_INFO
Make compression.zstd.zstd_version_info a named tuple.

This permits stable ABI extensions for multiple architectures to be
co-installed into the same directory, without clashing with each other,
the same way (non-stable ABI) regular extensions can.
It is listed before the current platform-less suffixes since it's more
specific.
The platform is stored in a new pyconfig.h define & sysconfig
variable, SOABI_PLATFORM.
On some known architectures (FreeBSD, Windows), this
will be undefined/zero; these won't have the new tag (yet).
Add SOABI_PLATFORM & ALT_SOABI the info to
`make pythoninfo` as well.

Use WMI to detect virtualization on Windows.
Replace wmic command with _wmi module to get the operating system caption and
version.
The wmic tool is deprecated since January 2024:
https://techcommunity.microsoft.com/blog/windows-itpro-blog/wmi-command-line-wmic-utility-deprecation-next-steps/4039242
For example, it's no longer installed in Windows images on GitHub
Action.
Fix also run_command(): no longer try to spawn a subprocess if the
platform doesn't support subprocess. It avoids logging run_command()
errors.
On Apple, log the hardware model as "system.hardware".
* Log the "CI", "IMAGE_OS_VERSION" and "container"
environment variables.
* Add run_command() and first_line() functions.
Prefer VMADDR_CID_LOCAL instead of VMADDR_CID_ANY for bind() in the
server. Skip the test if bind() fails with EADDRNOTAVAIL.
Log vsock CID in test.pythoninfo.
* introduce executable specific linker flags
Add PY_CORE_EXE_LDFLAGS and EXE_LDFLAGS which stores executable specific
LDFLAGS, replacing PY_CORE_LDFLAGS for building
executable targets.
If PY_CORE_EXE_LDFLAGS / EXE_LDFLAGS is not provided, then it defaults
to the value of PY_CORE_LDFLAGS which is the existing behaviour.
If both flags are supplied, and there is a need
to distinguish between executable and shared specific LDFLAGS,
in particular, PY_CORE_LDFLAGS should contain the shared specific LDFLAGS.
* documentation for new linker flags
* update Misc folder documentation
* Update Makefile.pre.in

* Implement C recursion protection with limit pointers for Linux, MacOS and Windows
* Remove calls to PyOS_CheckStack
* Add stack protection to parser
* Make tests more robust to low stacks
* Improve error messages for stack overflow
Revert "GH-91079: Implement C stack limits using addresses, not counters. (GH-130007)" for now
Unfortunatlely, the change broke some buildbots.
This reverts commit 2498c22fa0.
* Implement C recursion protection with limit pointers
* Remove calls to PyOS_CheckStack
* Add stack protection to parser
* Make tests more robust to low stacks
* Improve error messages for stack overflow
* Add mimalloc v2.12
Modified src/alloc.c to remove include of alloc-override.c and not
compile new handler.
Did not include the following files:
- include/mimalloc-new-delete.h
- include/mimalloc-override.h
- src/alloc-override-osx.c
- src/alloc-override.c
- src/static.c
- src/region.c
mimalloc is thread safe and shares a single heap across all runtimes,
therefore finalization and getting global allocated blocks across all
runtimes is different.
* mimalloc: minimal changes for use in Python:
- remove debug spam for freeing large allocations
- use same bytes (0xDD) for freed allocations in CPython and mimalloc
This is important for the test_capi debug memory tests
* Don't export mimalloc symbol in libpython.
* Enable mimalloc as Python allocator option.
* Add mimalloc MIT license.
* Log mimalloc in Lib/test/pythoninfo.py.
* Document new mimalloc support.
* Use macro defs for exports as done in:

Fix the test when run on an installed Python: use "abs_srcdir" of
sysconfig, and skip the test if the Python source code cannot be
found.
* Tools/patchcheck/patchcheck.py, Tools/freeze/test/freeze.py and
Lib/test/libregrtest/utils.py now first try to get "abs_srcdir"
from sysconfig, before getting "srcdir" from sysconfig.
* test.pythoninfo logs sysconfig "abs_srcdir".
Skip test_freeze_simple_script() of test_tools.test_freeze if Python
is built with "./configure --enable-optimizations", which means with
Profile Guided Optimization (PGO): it just makes the test too slow.
The freeze tool is tested by many other CIs with other (faster)
compiler flags.
test.pythoninfo now gets also get_build_info() of
test.libregrtests.utils.
On Emscripten and WASI, or if --python command line is used,
libregrtest now writes JSON into stdout, instead of using a name
file.
* Add JsonFileType.STDOUT.
* Remove JsonFileType.FILENAME.
* test.pythoninfo logs environment variables related to
cross-compilation and running Python on Emscripten/WASI.
