Use static inline function Py_EnterRecursiveCall() (#91988)
Currently, calling Py_EnterRecursiveCall() and
Py_LeaveRecursiveCall() may use a function call or a static inline
function call, depending if the internal pycore_ceval.h header file
is included or not. Use a different name for the static inline
function to ensure that the static inline function is always used in
Python internals for best performance. Similar approach than
PyThreadState_GET() (function call) and _PyThreadState_GET() (static
inline function).

* Rename _Py_EnterRecursiveCall() to _Py_EnterRecursiveCallTstate()
* Rename _Py_LeaveRecursiveCall() to _Py_LeaveRecursiveCallTstate()
* pycore_ceval.h: Rename Py_EnterRecursiveCall() to
  _Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() and
  _Py_LeaveRecursiveCall()

gh-91320: Use _PyCFunction_CAST() (#92251)
Replace "(PyCFunction)(void(*)(void))func" cast with
_PyCFunction_CAST(func).

Change generated by the command:

sed -i -e \
  's!(PyCFunction)(void(\*)(void)) *\([A-Za-z0-9_]\+\)!_PyCFunction_CAST(\1)!g' \
  $(find -name "*.c")

bpo-36819: Fix crashes in built-in encoders with weird error handlers (GH-28593)
If the error handler returns position less or equal than the starting
position of non-encodable characters, most of built-in encoders didn't
properly re-size the output buffer. This led to out-of-bounds writes,
and segfaults.

gh-91603: Speed up operator "|" for UnionType (GH-91955)
Reduce the complexity from O((M+N)^2) to O(M*N), where M and N are the length
of __args__ for both operands (1 for operand which is not a UnionType).

As a consequence, the complexity of parameter substitution in UnionType has
been reduced from O(N^3) to O(N^2).

gh-91731: Replace Py_BUILD_ASSERT() with static_assert() (#91730)
Python 3.11 now uses C11 standard which adds static_assert()
to <assert.h>.

* In pytime.c, replace Py_BUILD_ASSERT() with preprocessor checks on
  SIZEOF_TIME_T with #error.
* On macOS, py_mach_timebase_info() now accepts timebase members with
  the same size than _PyTime_t.
* py_get_monotonic_clock() now saturates GetTickCount64() to
  _PyTime_MAX: GetTickCount64() is unsigned, whereas _PyTime_t is
  signed.

gh-91421: Use constant value check during runtime (GH-91422)
The left-hand side expression of the if-check can be converted to a
constant by the compiler, but the addition on the right-hand side is
performed during runtime.

Move the addition from the right-hand side to the left-hand side by
turning it into a subtraction there. Since the values are known to
be large enough to not turn negative, this is a safe operation.

Prevents a very unlikely integer overflow on 32 bit systems.

Fixes GH-91421.

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.
