gh-57684: Add -P cmdline option and PYTHONSAFEPATH env var (#31542)
Add the -P command line option and the PYTHONSAFEPATH environment
variable to not prepend a potentially unsafe path to sys.path.

* Add sys.flags.safe_path flag.

* Programs/_bootstrap_python.c uses config.safe_path=0.
* Update subprocess._optim_args_from_interpreter_flags() to handle
  the -P command line option.
* Modules/getpath.py sets safe_path to 1 if a "._pth" file is
  present.

Convert the following macros to static inline functions:

gh-91768: C API no longer use "const PyObject*" type (#91769)
Py_REFCNT(), Py_TYPE(), Py_SIZE() and Py_IS_TYPE() functions argument
type is now "PyObject*", rather than "const PyObject*".

  * _Py_strhex_with_sep()
  * _Py_strhex_bytes_with_sep()

* Remove _PyObject_CAST_CONST() and _PyVarObject_CAST_CONST() macros.
* Py_IS_TYPE() can now use Py_TYPE() in its implementation.

bpo-46850: Move _PyInterpreterState_SetEvalFrameFunc() to internal C API (GH-32054)
Move the private _PyFrameEvalFunction type, and private
_PyInterpreterState_GetEvalFrameFunc() and
_PyInterpreterState_SetEvalFrameFunc() functions to the internal C
API. The _PyFrameEvalFunction callback function type now uses the
_PyInterpreterFrame type which is part of the internal C API.

Update the _PyFrameEvalFunction documentation.

bpo-46906: Add PyFloat_Pack8() to the C API (GH-31657)
Add new functions to pack and unpack C double (serialize and
deserialize):

* PyFloat_Pack2(), PyFloat_Pack4(), PyFloat_Pack8()
* PyFloat_Unpack2(), PyFloat_Unpack4(), PyFloat_Unpack8()

Document these functions and add unit tests.

Rename private functions and move them from the internal C API
to the public C API:

* _PyFloat_Pack2() => PyFloat_Pack2()
* _PyFloat_Pack4() => PyFloat_Pack4()
* _PyFloat_Pack8() => PyFloat_Pack8()
* _PyFloat_Unpack2() => PyFloat_Unpack2()
* _PyFloat_Unpack4() => PyFloat_Unpack4()
* _PyFloat_Unpack8() => PyFloat_Unpack8()

Replace the "unsigned char*" type with "char*" which is more common
and easy to use.

Minor fixes to C API docs (GH-31501)
* C API docs: move PyErr_SetImportErrorSubclass docs

It was in the section about warnings, but it makes more sense to
put it with PyErr_SetImportError.

It was already documented for PyRun_SimpleFileExFlags.

* textual fixes to unicode docs

* Move paragraph about tp_dealloc into tp_dealloc section

* __aiter__ returns an async iterator, not an awaitable

bpo-46608: exclude marshalled-frozen data if deep-freezing to save 300 KB space (GH-31074)
This reduces the size of the data segment by **300 KB** of the executable because if the modules are deep-frozen then the marshalled frozen data just wastes space. This was inspired by comment by @gvanrossum in https://github.com/python/cpython/pull/29118#issuecomment-958521863. Note: There is a new option `--deepfreeze-only` in `freeze_modules.py` to change this behavior, it is on be default to save disk space.

bpo-43931: Export Python version as API data (GH-25577)
When Python is embedded in other applications, it is not easy to determine which version of Python is being used. This change exposes the Python version as part of the API data. Tools like Austin (https://github.com/P403n1x87/austin) can benefit from this data when targeting applications like uWSGI, as the Python version can then be inferred systematically by looking at the exported symbols rather than relying on unreliable pattern matching or other hacks (like remote code execution etc...).

bpo-45582: Port getpath[p].c to Python (GH-29041)
The getpath.py file is frozen at build time and executed as code over a namespace. It is never imported, nor is it meant to be importable or reusable. However, it should be easier to read, modify, and patch than the previous code.

This commit attempts to preserve every previously tested quirk, but these may be changed in the future to better align platforms.
