* gh-112529: Remove PyGC_Head from object pre-header in free-threaded build This avoids allocating space for PyGC_Head in the free-threaded build. The GC implementation for free-threaded CPython does not use the PyGC_Head structure. * The trashcan mechanism uses the `ob_tid` field instead of `_gc_prev` in the free-threaded build. * The GDB libpython.py file now determines the offset of the managed dict field based on whether the running process is a free-threaded build. Those are identified by the `ob_ref_local` field in PyObject. * Fixes `_PySys_GetSizeOf()` which incorrectly incorrectly included the size of `PyGC_Head` in the size of static `PyTypeObject`. |

The Python C API ================ The C API is divided into these sections: 1. ``Include/``: Limited API 2. ``Include/cpython/``: CPython implementation details 3. ``Include/cpython/``, names with the ``PyUnstable_`` prefix: API that can change between minor releases 4. ``Include/internal/``, and any name with ``_`` prefix: The internal API Information on changing the C API is available `in the developer guide`_ .. _in the developer guide: https://devguide.python.org/c-api/
