For unsigned integer formats in the PyArg_Parse* functions,
accepting Python integers with value that is larger than
the maximal value the corresponding C type or less than
the minimal value for the corresponding signed integer type
is now deprecated.
Allow Py_LIMITED_API for (Py_GIL_DISABLED && _Py_OPAQUE_PYOBJECT)
API that's removed when _Py_OPAQUE_PYOBJECT is defined:
- PyObject_HEAD
- _PyObject_EXTRA_INIT
- PyObject_HEAD_INIT
- PyObject_VAR_HEAD
- struct _object (i.e. PyObject) (opaque)
- struct PyVarObject (opaque)
- Py_SIZE
- Py_SET_TYPE
- Py_SET_SIZE
- PyModuleDef_Base (opaque)
- PyModuleDef_HEAD_INIT
- PyModuleDef (opaque)
- _Py_IsImmortal
- _Py_IsStaticImmortal
Note that the `_Py_IsImmortal` removal (and a few other issues)
means _Py_OPAQUE_PYOBJECT only works with limited
API 3.14+ now.

* Fix flag mask inversion when unnamed flags exist.
For example:
class Flag(enum.Flag):
A = 0x01
B = 0x02
MASK = 0xff
~Flag.MASK is Flag(0)
* EJECT and KEEP flags (IntEnum is KEEP) use direct value.
* correct Flag inversion to only flip flag bits
IntFlag will flip all bits -- this only makes a difference in flag sets with
missing values.
* correct negative assigned values in flags
negative values are no longer used as-is, but become inverted; i.e.
class Y(self.enum_type):
A = auto()
B = auto()
C = ~A # aka ~1 aka 0b1 110 (from enum.bin()) aka 6
D = auto()
assert Y.C. is Y.B|Y.D
Implement a statistical sampling profiler that can profile external
Python processes by PID. Uses the _remote_debugging module and converts
the results to pstats-compatible format for analysis.

Weakrefs to unreachable garbage that are created during running of
finalizers need to be cleared. This avoids exposing objects that
have `tp_clear` called on them to Python-level code.
This is still formally undefined behaviour, but we may as well
keep the *same* undefined behaviour as previous versions.
PEP 796 proposes a cleaner and more consistent replacement for 3.15+
* Whitespaces no longer accepted between `</` and the tag name.
E.g. `</ script>` does not end the script section.
* Vertical tabulation (`\v`) and non-ASCII whitespaces no longer recognized
as whitespaces. The only whitespaces are `\t\n\r\f `.
* Null character (U+0000) no longer ends the tag name.
* Attributes and slashes after the tag name in end tags are now ignored,
instead of terminating after the first `>` in quoted attribute value.
E.g. `</script/foo=">"/>`.
* Multiple slashes and whitespaces between the last attribute and closing `>`
are now ignored in both start and end tags. E.g. `<a foo=bar/ //>`.
* Multiple `=` between attribute name and value are no longer collapsed.
E.g. `<a foo==bar>` produces attribute "foo" with value "=bar".
* Whitespaces between the `=` separator and attribute name or value are no
longer ignored. E.g. `<a foo =bar>` produces two attributes "foo" and
"=bar", both with value None; `<a foo= bar>` produces two attributes:
"foo" with value "" and "bar" with value None.
* Fix Sphinx errors.
* Apply suggestions from code review
