1. Use pkg-config to check for ncursesw/panelw. If that fails, use
pkg-config to check for ncurses/panel.
2. Regardless of pkg-config output, search for curses/panel headers, so
we're sure we have all defines in pyconfig.h.
3. Regardless of pkg-config output, check if libncurses or libncursesw
contains the 'initscr' symbol; if it does _and_ pkg-config failed
earlier, add the resulting -llib linker option to CURSES_LIBS.
Ditto for 'update_panels' and PANEL_LIBS.
4. Wrap the rest of the checks with WITH_SAVE_ENV and make sure we're
using updated LIBS and CPPFLAGS for those.
Add the PY_CHECK_CURSES convenience macro.

The code for Tier 2 is now only compiled when configured
with `--enable-experimental-jit[=yes|interpreter]`.
We drop support for `PYTHON_UOPS` and -`Xuops`,
but you can disable the interpreter or JIT
at runtime by setting `PYTHON_JIT=0`.
You can also build it without enabling it by default
using `--enable-experimental-jit=yes-off`;
enable with `PYTHON_JIT=1`.
On Windows, the `build.bat` script supports
`--experimental-jit`, `--experimental-jit-off`,
`--experimental-interpreter`.
In the C code, `_Py_JIT` is defined as before
when the JIT is enabled; the new variable
`_Py_TIER2` is defined when the JIT *or* the
interpreter is enabled. It is actually a bitmask:
1: JIT; 2: default-off; 4: interpreter.
Older libedit versions (like Apple's) use a different type signature
for rl_startup_hook and rl_pre_input_hook. Add a configure check to
determine which signature is accepted by introducing the
Py_RL_STARTUP_HOOK_TAKES_ARGS macro in pyconfig.h.

Keep Tools/build/deepfreeze.py around (we may repurpose it for deepfreezing non-code objects),
and keep basic "clean" targets that remove the output of former deep-freeze activities,
to keep the build directories of current devs clean.
Add a new C extension "_testlimitedcapi" which is only built with the
limited C API.
Move heaptype_relative.c and vectorcall_limited.c from
Modules/_testcapi/ to Modules/_testlimitedcapi/.
* configure: add _testlimitedcapi test extension.
* Update generate_stdlib_module_names.py.
* Update make check-c-globals.

If awailable, enable -fstrict-overflow for libmpdec. Also
shut off false positive warnings (-Warray-bounds).
The later was backported from mpdecimal-4.0.0.
This change is part of the work on PEP-738: Adding Android as a
supported platform.
* Remove the "1.0" suffix from libpython's filename on Android, which
would prevent Gradle from packaging it into an app.
* Simplify the build command in the Makefile so that libpython always
gets given an SONAME with the `-Wl-h` argument, even if the SONAME is
identical to the actual filename.
* Disable a number of functions on Android which can be compiled and
linked against, but always fail at runtime. As a result, the native
_multiprocessing module is no longer built for Android.
* gh-115390 (bee7bb331) added some pre-determined results to the
configure script for things that can't be autodetected when
cross-compiling; this change adds Android to these where appropriate.
* Add a couple more pre-determined results for Android, and making them
cover iOS as well. This means the --enable-ipv6 configure option will
no longer be required on either platform.
Part of the work on PEP 738: Adding Android as a supported platform.
* Rename the LIBPYTHON variable to MODULE_LDFLAGS, to more accurately
reflect its purpose.
* Edit makesetup to use MODULE_LDFLAGS when linking extension modules.
* Edit the Makefile so that extension modules depend on libpython on
Android and Cygwin.
* Restore `-fPIC` on Android. It was removed several years ago with a
note that the toolchain used it automatically, but this is no longer
the case. Omitting it causes all linker commands to fail with an error
like `relocation R_AARCH64_ADR_PREL_PG_HI21 cannot be used against
symbol '_Py_FalseStruct'; recompile with -fPIC`.
Part of the PEP 730 work to add iOS support.
This change lays the groundwork for introducing iOS/tvOS/watchOS
frameworks; it includes the structural refactoring needed so that iOS
branches can be added into in a subsequent PR.
Summary of changes:
* Updates config.sub to the 2024-01-01 release. This is the "as
released" version of config.sub.
* Adds a RESSRCDIR variable to allow sharing of macOS and iOS Makefile
steps.
* Adds an INSTALLTARGETS variable so platforms can customise which
targets are actually installed. This will be used to exclude certain
targets (e.g., binaries, manfiles) from iOS framework installs.
* Adds a PYTHONFRAMEWORKINSTALLNAMEPREFIX variable; this is used as
the install name for the library. This is needed to allow for iOS
frameworks to specify an @rpath-based install name.
* Evaluates MACHDEP earlier in the configure process so that
ac_sys_system is available.
* Modifies _PYTHON_HOST_PLATFORM evaluation for cross-platform builds
so that the CPU architecture is differentiated from the host
identifier. This will be used to generate a _PYTHON_HOST_PLATFORM
definition that includes ABI information, not just CPU architecture.
* Differentiates between SOABI_PLATFORM and PLATFORM_TRIPLET.
SOABI_PLATFORM is used in binary module names, and includes the ABI,
but not the OS or CPU architecture (e.g.,
math.cpython-313-iphonesimulator.dylib). PLATFORM_TRIPLET is used
as the sys._multiarch value, and on iOS will contains the ABI and
architecture (e.g., iphoneos-arm64). This differentiation hasn't
historically been needed because while macOS is a multiarch platform,
it uses a bare darwin as PLATFORM_TRIPLE.
* Removes the use of the deprecated -Wl,-single_module flag when
compiling macOS frameworks.
* Some whitespace normalisation where there was a mix of spaces and tabs
in a single block.
