In expression (?(group)...) an appropriate re.error is now
raised if the group number refers to not defined group.

Previously it raised RuntimeError: invalid SRE code.

re.error is now raised instead of TypeError.

Macros Py_DECREF, Py_XDECREF, Py_IS_TYPE, _Py_atomic_load_32bit_impl
and _Py_DECREF_SPECIALIZED are redefined as macros
that completely replace the inline functions of the same name.
These three came out in the top four of functions that (in MSVC)
somehow weren't inlined.

Closes GH-91764

Deprecate functions:

* PyUnicode_AS_DATA()
* PyUnicode_AS_UNICODE()
* PyUnicode_GET_DATA_SIZE()
* PyUnicode_GET_SIZE()

Previously, these functions were macros and so it wasn't possible to
decorate them with Py_DEPRECATED().

Convert unicodeobject.h macros to static inline functions:

* PyUnicode_AS_DATA()
* PyUnicode_AS_UNICODE()
* PyUnicode_GET_DATA_SIZE()
* PyUnicode_GET_SIZE()

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

If Python is built in debug mode, _Py_Dealloc() now ensures that the
tp_dealloc function leaves the current exception unchanged.

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.

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*".

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.
