#105828)

* The following tests were disabled since the initial ctypes commit
  in 2006, commit babddfc:

  * Callbacks.test_char_p()
  * DeletePointerTestCase.test_X()
  * NumberTestCase.test_perf()
  * StructureTestCase.test_subclass_creation()
  * Tests.test_X() of test_byteswap

* NumberTestCase.test_bool_from_address() was disabled in 2007 by
  commit 5dc4fe0.
* Remove check_perf() and run_test() of test_numbers.

Use a raw f-string in test_httpservers.py

The MACHINE variable is no longer used in test_structures.

Reenable 3 tests:

* test_overflow()
* test_basic_wstrings()
* test_toolong()

* Remove "except: print(tp); raise" debug code.
* Remove unused NoNullHandle() function.
* Remove commented code.

Re-arrange `pathlib.Path` test methods in source code. No other changes.

The test methods are arranged in two groups. The first group checks
`stat()`, `open()`, `iterdir()`, `readlink()`, and derived methods like
`exists()`, `read_text()`, `glob()` and `resolve()`. The second group
checks all other `Path` methods. To minimise the diff I've maintained the
method order within groups where possible.

This patch prepares the ground for a new `_AbstractPath` class, which will
support methods in the first group above. By churning the test methods
here, subsequent patches will be easier to review and less likely to break
things.

…ces (#105801)

* Move imports at top level and sort imports.
* Replace c_buffer() with create_string_buffer(): c_buffer is a
  deprecated alias.
* PEP 8: Add empty lines for readability between imports and classes.

* Replace operator.delitem(obj, index) with "del obj[index]".
* Replace operator.setitem(obj, index, value) with
  "obj[index] = value".
* Replace delattr(obj, "attr) with "del obj.attr".
* Replace grc() with sys.getrefcount() for readability.

Remove the @need_symbol('...') decorator of test.test_ctypes since
requested symbols are now always always available in ctypes.

Use the @unittest.skipUnless() decorator directly for the two types
only available on Windows:

* ctypes.WINFUNCTYPE
* ctypes.oledll

test_xmlrpc_net was skipped since 2017:
commit 73ffd3f.

The public buildbot.python.org server has no XML-RPC interface
anymore, and no replacement server was found in 6 years.

* Clarify things around goto error/ERROR_IF a bit
* Remove docs for super-instructions
* Add pseudo; fix heading markup

Reimplement _iso8601_format() using the datetime isoformat() method.
Ignore the timezone.

Deprecate two methods of creating typing.TypedDict classes with 0 fields using the functional syntax: `TD = TypedDict("TD")` and `TD = TypedDict("TD", None)`. Both will be disallowed in Python 3.15. To create a TypedDict class with 0 fields, either use `class TD(TypedDict): pass` or `TD = TypedDict("TD", {})`.

…of an internal frame. (GH-105727)

* Add table describing possible executable classes for out-of-process debuggers.

* Remove shim code object creation code as it is no longer needed.

* Make lltrace a bit more robust w.r.t. non-standard frames.

Deprecate creating a typing.NamedTuple class using keyword arguments to denote the fields (`NT = NamedTuple("NT", x=int, y=str)`). This will be disallowed in Python 3.15. Use the class-based syntax or the functional syntax instead.

Two methods of creating `NamedTuple` classes with 0 fields using the functional syntax are also deprecated, and will be disallowed in Python 3.15: `NT = NamedTuple("NT")` and `NT = NamedTuple("NT", None)`. To create a `NamedTuple` class with 0 fields, either use `class NT(NamedTuple): pass` or `NT = NamedTuple("NT", [])`.

Remove compatibility code for Python 2 and early Python 3 versions.

* Remove os_fsencode() reimplementation: use os.fsencode() directly.
  os.fsencode() was added to Python 3.2.
* Remove references to Python 2 and "Python 3": just say "Python".
* Remove outdated u'' string format: use '' instead.

Replace #pragma with _Py_COMP_DIAG_PUSH,
_Py_COMP_DIAG_IGNORE_DEPR_DECLS and _Py_COMP_DIAG_POP to ease Python
maintenance. Also add a comment explaining why callbacks.c ignores a
deprecation warning.

The syntax used in the current docs (a / before any args) is invalid.

I think the right approach is for the arguments to arbitrary
filter functions to be treated as positional-only, meaning that users
can supply filter functions with any names for the argument. tarfile.py
only calls the filter function with positional arguments.
