gh-100240: Use a consistent implementation for freelists (#121934)
This combines and updates our freelist handling to use a consistent
implementation. Objects in the freelist are linked together using the
first word of memory block.

If configured with freelists disabled, these operations are essentially
no-ops.

gh-120522: Apply App Store compliance patch during installation (#121947)
Adds a --with-app-store-compliance configuration option that patches out code known to be an issue with App Store review processes. This option is applied automatically on iOS, and optionally on macOS.

gh-121103: Put free-threaded libraries in `lib/python3.14t` (#121293)
On POSIX systems, excluding macOS framework installs, the lib directory
for the free-threaded build now includes a "t" suffix to avoid conflicts
with a co-located default build installation.

gh-117139: Convert the evaluation stack to stack refs (#118450)
This PR sets up tagged pointers for CPython.

The general idea is to create a separate struct _PyStackRef for everything on the evaluation stack to store the bits. This forces the C compiler to warn us if we try to cast things or pull things out of the struct directly.

Only for free threading: We tag the low bit if something is deferred - that means we skip incref and decref operations on it. This behavior may change in the future if Mark's plans to defer all objects in the interpreter loop pans out.

This implies a strict stack reference discipline is required. ALL incref and decref operations on stackrefs must use the stackref variants. It is unsafe to untag something then do normal incref/decref ops on it.

The new incref and decref variants are called dup and close. They mimic a "handle" API operating on these stackrefs.

Please read Include/internal/pycore_stackref.h for more information!

gh-119344: Make critical section API public (#119353)
This makes the following macros public as part of the non-limited C-API for
locking a single object or two objects at once.

* `Py_BEGIN_CRITICAL_SECTION(op)` / `Py_END_CRITICAL_SECTION()`
* `Py_BEGIN_CRITICAL_SECTION2(a, b)` / `Py_END_CRITICAL_SECTION2()`

The supporting functions and structs used by the macros are also exposed for
cases where C macros are not available.

Mostly uses a stop-the-world approach and synchronization around the code object's _co_instrumentation_version.  There may be a little bit of extra synchronization around the monitoring data that's required to be TSAN clean.

gh-116968: Reimplement Tier 2 counters (#117144)
Introduce a unified 16-bit backoff counter type (``_Py_BackoffCounter``),
shared between the Tier 1 adaptive specializer and the Tier 2 optimizer. The
API used for adaptive specialization counters is changed but the behavior is
(supposed to be) identical.

The behavior of the Tier 2 counters is changed:
- There are no longer dynamic thresholds (we never varied these).
- All counters now use the same exponential backoff.
- The counter for ``JUMP_BACKWARD`` starts counting down from 16.
- The ``temperature`` in side exits starts counting down from 64.

gh-71052: Fix several Android build issues (#115955)
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.
