gh-83754: Use the Py_TYPE() macro (#120599)
Don't access directly PyObject.ob_type, but use the Py_TYPE() macro
instead.

gh-110850: Remove _PyTime_TimeUnchecked() function (#118552)
Use the new public Raw functions:

* _PyTime_PerfCounterUnchecked() with PyTime_PerfCounterRaw()
* _PyTime_TimeUnchecked() with PyTime_TimeRaw()
* _PyTime_MonotonicUnchecked() with PyTime_MonotonicRaw()

Remove internal functions:

* _PyTime_PerfCounterUnchecked()
* _PyTime_TimeUnchecked()
* _PyTime_MonotonicUnchecked()

GH-117108: Set the "old space bit" to "visited" for all young objects (#117213)
Change old space bit of young objects from 0 to gcstate->visited_space.
This ensures that any object created *and* collected during cycle GC has the bit set correctly.

A few minor tweaks to get stats working and compiling cleanly. (#117219)
Fixes a compilation error when configured with `--enable-pystats`,
an array size issue, and an unused variable.

gh-110850: Use public PyTime functions (#115746)
Replace private _PyTime functions with public PyTime functions.

random_seed_time_pid() now reports errors to its caller.

gh-110850: Rename internal PyTime C API functions (#115734)
Rename functions:

* _PyTime_GetSystemClock() => _PyTime_TimeUnchecked()
* _PyTime_GetPerfCounter() => _PyTime_PerfCounterUnchecked()
* _PyTime_GetMonotonicClock() => _PyTime_MonotonicUnchecked()
* _PyTime_GetSystemClockWithInfo() => _PyTime_TimeWithInfo()
* _PyTime_GetMonotonicClockWithInfo() => _PyTime_MonotonicWithInfo()
* _PyTime_GetMonotonicClockWithInfo() => _PyTime_MonotonicWithInfo()

Changes:

* Remove "typedef PyTime_t PyTime_t;" which was
  "typedef PyTime_t _PyTime_t;" before a previous rename.
* Update comments of "Unchecked" functions.
* Remove invalid PyTime_Time() comment.

gh-110850: Cleanup pycore_time.h includes (#115724)
<pycore_time.h> include is no longer needed to get the PyTime_t type
in internal header files. This type is now provided by <Python.h>
include. Add <pycore_time.h> includes to C files instead.

gh-112175: Add `eval_breaker` to `PyThreadState` (#115194)
This change adds an `eval_breaker` field to `PyThreadState`. The primary
motivation is for performance in free-threaded builds: with thread-local eval
breakers, we can stop a specific thread (e.g., for an async exception) without
interrupting other threads.

The source of truth for the global instrumentation version is stored in the
`instrumentation_version` field in PyInterpreterState. Threads usually read the
version from their local `eval_breaker`, where it continues to be colocated
with the eval breaker bits.

gh-112529: Implement GC for free-threaded builds (#114262)
* gh-112529: Implement GC for free-threaded builds

This implements a mark and sweep GC for the free-threaded builds of
CPython. The implementation relies on mimalloc to find GC tracked
objects (i.e., "containers").

gh-112529: Use GC heaps for GC allocations in free-threaded builds (gh-114157)
* gh-112529: Use GC heaps for GC allocations in free-threaded builds

The free-threaded build's garbage collector implementation will need to
find GC objects by traversing mimalloc heaps. This hooks up the
allocation calls with the correct heaps by using a thread-local
"current_obj_heap" variable.

* Refactor out setting heap based on type

gh-113688: Split up gcmodule.c (gh-113715)
This splits part of Modules/gcmodule.c of into Python/gc.c, which
now contains the core garbage collection implementation. The Python
module remain in the Modules/gcmodule.c file.
