bpo-46417: Finalize structseq types at exit (GH-30645)
Add _PyStructSequence_FiniType() and _PyStaticType_Dealloc()
functions to finalize a structseq static type in Py_Finalize().
Currrently, these functions do nothing if Python is built in release
mode.

Clear static types:

* AsyncGenHooksType: sys.set_asyncgen_hooks()
* FlagsType: sys.flags
* FloatInfoType: sys.float_info
* Hash_InfoType: sys.hash_info
* Int_InfoType: sys.int_info
* ThreadInfoType: sys.thread_info
* UnraisableHookArgsType: sys.unraisablehook
* VersionInfoType: sys.version
* WindowsVersionType: sys.getwindowsversion()

bpo-45953: Statically initialize the small ints. (gh-30092)
The array of small PyLong objects has been statically declared. Here I also statically initialize them. Consequently they are no longer initialized dynamically during runtime init.

I've also moved them under a new sub-struct in _PyRuntimeState, in preparation for static allocation and initialization of other global objects.

bpo-46008: Make runtime-global object/type lifecycle functions and state consistent. (gh-29998)
This change is strictly renames and moving code around.  It helps in the following ways:

* ensures type-related init functions focus strictly on one of the three aspects (state, objects, types)
* passes in PyInterpreterState * to all those functions, simplifying work on moving types/objects/state to the interpreter
* consistent naming conventions help make what's going on more clear
* keeping API related to a type in the corresponding header file makes it more obvious where to look for it

bpo-35134: Add Include/cpython/longobject.h (GH-29044)
Move Include/longobject.h non-limited API to a new
Include/cpython/longobject.h header file.

Move the following definitions to the internal C API:

* _PyLong_DigitValue
* _PyLong_FormatAdvancedWriter()
* _PyLong_FormatWriter()

bpo-43687: Py_Initialize() creates singletons earlier (GH-25147)
Reorganize pycore_interp_init() to initialize singletons before the
the first PyType_Ready() call. Fix an issue when Python is configured
using --without-doc-strings.

bpo-43268: Replace _PyThreadState_GET() with _PyInterpreterState_GET() (GH-24576)
Replace _PyThreadState_GET() with _PyInterpreterState_GET() in
functions which only need the current interpreter, but don't need the
current Python thread state.

Replace also _PyThreadState_UncheckedGet() with _PyThreadState_GET()
in faulthandler.c, since _PyThreadState_UncheckedGet() is just an
alias to _PyThreadState_GET() in practice.

bpo-42161: Add _PyLong_GetZero() and _PyLong_GetOne() (GH-22993)
Add _PyLong_GetZero() and _PyLong_GetOne() functions and a new
internal pycore_long.h header file.

Python cannot be built without small integer singletons anymore.
