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*".

* Replace also "const PyObject*" with "PyObject*" in functions:

  * _Py_strhex_impl()
  * _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.

gh-89653: PEP 670: Convert unicodeobject.h macros to functions (#91773)
Convert unicodeobject.h macros to static inline functions:

* PyUnicode_MAX_CHAR_VALUE()
* PyUnicode_READ()
* PyUnicode_READY()
* PyUnicode_READ_CHAR()
* PyUnicode_WRITE()

Move PyUnicode_READY() after _PyUnicode_Ready(), since it uses
_PyUnicode_Ready().

Static inline functions are wrapped by macros which casts arguments
with _PyObject_CAST() and casts 'kind' arguments to "unsigned int" to
prevent introducing new compiler warnings when passing "const
PyObject*".

GH-91719: Make MSVC generate somewhat faster switch code (#91718)
Apparently a switch on an 8-bit quantity where all cases are
present generates a more efficient jump (doing only one indexed
memory load instead of two).

So we make opcode and use_tracing uint8_t, and generate a macro
full of extra `case NNN:` lines for all unused opcodes.

See https://github.com/faster-cpython/ideas/issues/321#issuecomment-1103263673

gh-89653: PEP 670: Convert tuple macros to functions (#91786)
Convert macros to static inline functions:

* PyTuple_GET_SIZE()
* PyTuple_SET_ITEM()
* PyList_GET_SIZE()
* PyList_SET_ITEM()

Add a macro converting arguments to PyTupleObject*, PyListObject* or
PyObject* to prevent emitting new compiler warnings.

According to PEP 670, PyTuple_GET_ITEM() and PyList_GET_ITEM() are
left as macros.

gh-89653: PEP 670: Convert PyWeakref_GET_OBJECT() to function (#91785)
Convert the PyWeakref_GET_OBJECT() macro to a static inline function.
Add an assertion to check the argument with PyWeakref_Check(). Add a
macro converting the argument to PyObject* to prevent emitting new
compiler warning.

gh-89653: PEP 670: Convert unicodeobject.h macros to functions (#91705)
Convert unicodeobject.h macros to static inline functions:

* PyUnicode_CHECK_INTERNED()
* PyUnicode_DATA(), _PyUnicode_COMPACT_DATA(),
  _PyUnicode_NONCOMPACT_DATA()
* PyUnicode_GET_LENGTH()
* PyUnicode_IS_ASCII()
* PyUnicode_IS_COMPACT()
* PyUnicode_IS_COMPACT_ASCII()
* PyUnicode_IS_READY()

Reorder functions to declare functions before their first usage.

Static inline functions are wrapped by macros which casts
arguments with _PyObject_CAST() to prevent introducing
new compiler warnings when passing "const PyObject*".

bpo-45995: add "z" format specifer to coerce negative 0 to zero (GH-30049)
Add "z" format specifier to coerce negative 0 to zero.

See https://github.com/python/cpython/issues/90153 (originally https://bugs.python.org/issue45995) for discussion.
This covers `str.format()` and f-strings.  Old-style string interpolation is not supported.

bpo-44800: Document internal frame naming conventions (GH-32281)
The fact interpreter frames were split out from full frame objects
rather than always being part of the eval loop implementation means
that it's tricky to infer the expected naming conventions simply
from looking at the code.

Documenting the de facto conventions in pycore_frame.h means future
readers of the code will have a clear explanation of the rationale
for those conventions (i.e. minimising non-functional code churn).
