Accepting request 1299348 from devel:languages:python

Forwarded request #1299226 from mcalabkova

- Update to 3.1.3
    * Some method calls with 0 or 1 argument failed to use PyObject_VectorCallMethod().
    * Walrus assignments of literal Python integers could generate invalid C code.
    * cython.pythread_type_lock (also used as fallback for cython.pymutex) could stall
      on heavily contended locks.
    * C string arrays (not pointers) always coerced to the Python default string type,
      even on explicit casts to other string types.
    * Unterminated \N{} character escapes in strings could unrail the parser.
    * An internal C function was not marked as static and leaked a linker symbol.
    * Some Unicode letters were not recognised as lexically valid name parts.
    * Compatibility with PyPy3.8 was lost by accident.
    * The Linux binary wheels of 3.1.2 used SSSE3 CPU instructions which are not
      available on some CPUs.
  - Convert to libalternatives on SLE-16-based and newer systems only

+- Update top 3.1.2
+  * Attribute lookups failed on the ``bool`` builtin type.
+    (Github issue :issue:`6905`)
+  * Type checks on or-ed union types could incorrectly return false.
+    (Github issue :issue:`6420`)
+  * Negative list indexing could accidentally wrap around twice in PyPy and the Limited API.
+  * Iterating over literal sequences with starred (unpacked) items could infer a wrong
+    type for the loop variable and fail to assign the values.
+    (Github issue :issue:`6924`)
+  * Calls to C functions taking exception types failed to check for a `None` argument.
+    (Github issue :issue:`6420`)
+  * Fused functions had an incorrect ``__module__`` attribute.
+    (Github issue :issue:`6897`)
+  * The type of Cython implemented functions had an incorrect ``__module__`` attribute.
+    (Github issue :issue:`6841`)
+  * Errors while indexing into ``bytearray`` or ``str`` in ``nogil`` sections could crash.
+    (Github issue :issue:`6947`)
+  * ``bytearray.append()`` could silently accept some invalid character numbers.
+  * The C++11 ``<type_traits>`` header was included regardless of the C++ version.
+    (Github issue :issue:`6896`)
+  * ``PyDict_GetItemStringRef()`` was accidentally used in older Limited API versions.
+    (Github issue :issue:`6914`)
+  * ``abort()`` was used but not always available in the Limited API.
+    (Github issue :issue:`6918`)
+  * Some dependencies were missing from the ``depfile``.
+    (Github issue :issue:`6938`)
+  * Embedded function signatures were not always separated from the existing docstring.
+    (Github issue :issue:`6904`)
+  * ``numpy.math`` was missing from ``Cython/Includes/`` and could not be cimported.
+    (Github issue :issue:`6859`)
+  * Some tests were adapted for NumPy 2.x.
+    (Github issue :issue:`6898`)
+  * Some C compiler warnings were fixed.
+    (Github issue :issue:`6870`)
+  * ``Cython.Build`` was not officially exposing the ``cythonize`` function.
+    (Github issue :issue:`6934`)
+- Changes from 3.1.1
+  * A reference leak in the async delegation code was fixed.
+    (Github issues :issue:`6850`, :issue:`6878`)
+  * Conditional if-else expressions mixing Python and C (numeric) types could end up
+    inferring an overly tight result type, thus leading to unexpected type conversions,
+    runtime exceptions on assignment, or incorrect "temporary assignment" compile errors.
+    (Github issue :issue:`6854`)
+  * Some Limited API issues were resolved.
+    (Github issue :issue:`6862`)
+  * Large C ``long long`` values could be truncated when passed into PyPy.
+    (Github issue :issue:`6890`)
+  * ``callable()`` incorrectly reported ``False`` in PyPy for classes with metaclasses.
+    Patch by Anatolii Aniskovych. (Github issue :issue:`6892`)
+  * The signature of fused functions was no longer introspectable in Cython 3.1.0.
+    (Github issue :issue:`6855`)
+  * Coroutines could generate invalid C with line tracing enabled.
+    (Github issue :issue:`6865`)
+  * Code using ``complex()`` could generate invalid C code missing type declarations.
+    (Github issue :issue:`6860`)
+  * Code using e.g. ``list[int | None]``  outside of variable/argument annotations failed to compile.
+    (Github issue :issue:`6856`)
+  * Code using ctuples in a ``const`` context could generate invalid C.
+    (Github issue :issue:`6864`)
+  * Accessing special methods on cpdef enums failed to compile.
+  * Some C compiler warnings were resolved.
+    Patches by Daniel Larraz.  (Github issues :issue:`6876`, :issue:`3172`, :issue:`6873`, :issue:`6877`)
+  * Re-establish support for PyPy 3.8.
+    (Github issue :issue:`6867`)
