gh-115011: Improve support of __index__() in setters of members with unsigned integer type (GH-115029)
Setters for members with an unsigned integer type now support
the same range of valid values for objects that has a __index__()
method as for int.

Previously, Py_T_UINT, Py_T_ULONG and Py_T_ULLONG did not support
objects that has a __index__() method larger than LONG_MAX.

Py_T_ULLONG did not support negative ints. Now it supports them and
emits a RuntimeWarning.

gh-114392: Improve test_capi.test_structmembers (GH-114393)
Test all integer member types with extreme values and values outside of
the valid range. Test support of integer-like objects. Test warnings for
wrapped out values.

gh-114388: Fix warnings when assign an unsigned integer member (GH-114391)
* Fix a RuntimeWarning emitted when assign an integer-like value that
  is not an instance of int to an attribute that corresponds to a C
  struct member of type T_UINT and T_ULONG.
* Fix a double RuntimeWarning emitted when assign a negative integer value
  to an attribute that corresponds to a C struct member of type T_UINT.

gh-47146: Soft-deprecate structmember.h, expose its contents via Python.h (GH-99014)
The ``structmember.h`` header is deprecated, though it continues to be available
and there are no plans to remove it. There are no deprecation warnings. Old code
can stay unchanged (unless the extra include and non-namespaced macros bother
you greatly). Specifically, no uses in CPython are updated -- that would just be
unnecessary churn.
The ``structmember.h`` header is deprecated, though it continues to be
available and there are no plans to remove it.

Its contents are now available just by including ``Python.h``,
with a ``Py`` prefix added if it was missing:

- `PyMemberDef`, `PyMember_GetOne` and`PyMember_SetOne`
- Type macros like `Py_T_INT`, `Py_T_DOUBLE`, etc.
  (previously ``T_INT``, ``T_DOUBLE``, etc.)
- The flags `Py_READONLY` (previously ``READONLY``) and
  `Py_AUDIT_READ` (previously all uppercase)

Several items are not exposed from ``Python.h``:

- `T_OBJECT` (use `Py_T_OBJECT_EX`)
- `T_NONE` (previously undocumented, and pretty quirky)
- The macro ``WRITE_RESTRICTED`` which does nothing.
- The macros ``RESTRICTED`` and ``READ_RESTRICTED``, equivalents of
  `Py_AUDIT_READ`.
- In some configurations, ``<stddef.h>`` is not included from ``Python.h``.
  It should be included manually when using ``offsetof()``.

The deprecated header continues to provide its original
contents under the original names.
Your old code can stay unchanged, unless the extra include and non-namespaced
macros bother you greatly.

There is discussion on the issue to rename `T_PYSSIZET` to `PY_T_SSIZE` or
similar. I chose not to do that -- users will probably copy/paste that with any
spelling, and not renaming it makes migration docs simpler.
