gh-106320: Re-add some PyLong/PyDict C-API functions (GH-#111162)
* gh-106320: Re-add _PyLong_FromByteArray(), _PyLong_AsByteArray() and _PyLong_GCD() to the public header files since they are used by third-party packages and there is no efficient replacement.

See https://github.com/python/cpython/issues/111140
See https://github.com/python/cpython/issues/111139

* gh-111262: Re-add _PyDict_Pop() to have a C-API until a new public one is designed.

gh-106320: Remove private _Py_Identifier API (#108593)
Remove the private _Py_Identifier type and related private functions
from the public C API:

* _PyObject_LookupSpecialId()
* _PyObject_SetAttrId()
* _PyType_LookupId()
* _Py_IDENTIFIER()
* _Py_static_string()
* _Py_static_string_init()

Move them to the internal C API: add a new pycore_identifier.h header
file. No longer export these functions.

* _PyDictView_New()
* _PyDict_ContainsId()
* _PyDict_DelItemId()

No longer export most of these functions.

Move also the _PyDictViewObject structure to the internal C API.

Move dict_getitem_knownhash() function from _testcapi to the
_testinternalcapi extension. Update test_capi.test_dict for this
change.

gh-108308: Remove _PyDict_GetItemStringWithError() function (#108426)
Remove the internal _PyDict_GetItemStringWithError() function. It can
now be replaced with the new public PyDict_ContainsString() and
PyDict_GetItemStringRef() functions.

getargs.c now now uses a strong reference for current_arg.
find_keyword() returns a strong reference.

gh-106320: Remove _PyDict_GetItemStringWithError() function (#108313)
Remove private _PyDict_GetItemStringWithError() function of the
public C API: the new PyDict_GetItemStringRef() can be used instead.

* Move private _PyDict_GetItemStringWithError() to the internal C API.
* _testcapi get_code_extra_index() uses PyDict_GetItemStringRef().
  Avoid using private functions in _testcapi which tests the public C
  API.

gh-99845: Change _PyDict_KeysSize() return type to size_t (#99848)
* Change _PyDict_KeysSize() and shared_keys_usable_size() return type
  from signed (Py_ssize_t) to unsigned (size_t) type.
* new_values() argument type is now unsigned (size_t).
* init_inline_values() now uses size_t rather than int for the 'i'
  iterator variable.
* type.__sizeof__() implementation now uses unsigned (size_t) type.

Use _Py_RVALUE() in macros (#99844)
The following macros are modified to use _Py_RVALUE(), so they can no
longer be used as l-value:

* DK_LOG_SIZE()
* _PyCode_CODE()
* _PyList_ITEMS()
* _PyTuple_ITEMS()
* _Py_SLIST_HEAD()
* _Py_SLIST_ITEM_NEXT()

_PyCode_CODE() is private and other macros are part of the internal
C API.

gh-89653: PEP 670: Convert macros to functions (#99843)
Convert macros to static inline functions to avoid macro pitfalls,
like duplication of side effects:

* DK_ENTRIES()
* DK_UNICODE_ENTRIES()
* PyCode_GetNumFree()
* PyFloat_AS_DOUBLE()
* PyInstanceMethod_GET_FUNCTION()
* PyMemoryView_GET_BASE()
* PyMemoryView_GET_BUFFER()
* PyMethod_GET_FUNCTION()
* PyMethod_GET_SELF()
* PySet_GET_SIZE()
* _PyHeapType_GET_MEMBERS()

Changes:

* PyCode_GetNumFree() casts PyCode_GetNumFree.co_nfreevars from int
  to Py_ssize_t to be future proof, and because Py_ssize_t is
  commonly used in the C API.
* PyCode_GetNumFree() doesn't cast its argument: the replaced macro
  already required the exact type PyCodeObject*.
* Add assertions in some functions using "CAST" macros to check
  the arguments type when Python is built with assertions
  (debug build).
* Remove an outdated comment in unicodeobject.h.

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
