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-91719: Add pycore_opcode.h internal header file (#91906) 
Move the following API from Include/opcode.h (public C API) to a new
Include/internal/pycore_opcode.h header file (internal C API):

* EXTRA_CASES
* _PyOpcode_Caches
* _PyOpcode_Deopt
* _PyOpcode_Jump
* _PyOpcode_OpName
* _PyOpcode_RelativeJump

gh-89373: _Py_Dealloc() checks tp_dealloc exception (#32357) 
If Python is built in debug mode, _Py_Dealloc() now ensures that the
tp_dealloc function leaves the current exception unchanged.

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.
