Stephen Rosen 50fe49c879 gh-150319: Replace all documentation which says "See PEP 585" (#150325)
* Replace all documentation which says "See PEP 585"

The following classes in the stdlib get simple updates:

- array.array
- asyncio.Future
- asyncio.Task
- collections.defaultdict
- collections.deque
- contextvars.ContextVar
- contextvars.Token
- ctypes.Array
- os.DirEntry
- re.Match
- re.Pattern
- string.templatelib.Interpolation
- string.templatelib.Template
- types.MappingProxyType
- queue.SimpleQueue
- weakref.ref

The following classes are documented publicly as functions, and are
therefore updated internally (`__class_getitem__.__doc__`) but not in the
public docs:

- functools.partial
- itertools.chain

The following builtin types have updates to `__class_getitem__.__doc__`
but not to any documentation pages:

- BaseExceptionGroup
- coroutines (from generators)
- dict
- enumerate
- frozendict
- frozenset
- generators (and async generators)
- list
- memoryview
- set
- slice
- tuple

Special cases:

- union objects are now documented as "supporting class-level []",
  rather than anything to do with generics.

- Templates might be generic over a single type (union, in theory) or
  over a TypeVarTuple. As this is not currently fully settled, it is
  marked with a comment and a mild hint that it is a single type is used
  (namely, "type" is singular rather than "types", plural)

* Apply suggestions from code review

Co-authored-by: Jelle Zijlstra <jelle.zijlstra@gmail.com>

* Correct several class getitem docs

And expand the text for tuples.

Co-authored-by: Jelle Zijlstra <906600+JelleZijlstra@users.noreply.github.com>

* Add notes on generic typing of builtins

* Fix typo in tuple.__class_getitem__ docstring

* Typo fix: malformed refs

Fix `generic` links which weren't marked as `:ref:`.

* Strike unnecessary docs on generic-ness

Co-authored-by: Jelle Zijlstra <906600+JelleZijlstra@users.noreply.github.com>

* Apply suggestions from code review

These are applied at both the originally indicated locations and in the
corresponding docstring definitions.

* Update Doc/library/re.rst

Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com>

* Update Objects/enumobject.c

Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com>

* Remove tuple generic doc in 'stdtypes' page

This is covered in more detail in the cross-linked typing documentation.
The other copy of this documentation -- in the docstring for
`tuple.__class_getitem__` -- is left in place.

* Fix whitespace around new doc of generics

Per review, do not introduce or remove whitespace such that section
breaks are altered by the introduction of doc on various generic types.

In most cases, this is a removal of an extra line.

In one case (Arrays), it is the reintroduction of a line.

Additionally, two other minor fixes are included:
- incorrect indent on 'defaultdicts'
- make `mappingproxy.__class_getitem__.__doc__` consistent with other
  mapping type generic docs

* Move placement of memoryview generic note

Previous placement was at the end of the main docstring, which is
consistent with other types but places it after a section on various
methods (which makes it read somewhat inconsistently). Moving it up
helps resolve.

* Ensure sphinxdoc does not start sentences lowercase

Lowercase class names at the start of sentences are marked out with the
`class` role. In the case of `deque`, documentation already refers to
these as `Deques`, so this form is preferred.

* Apply suggestions from code review

Co-authored-by: Bénédikt Tran <10796600+picnixz@users.noreply.github.com>

* Fix line endings and wrap more tightly

Line endings fixed by pre-commit ; also re-wrapped the MappingProxyType
text which was too long.

* Use 'ContextVars' style in sphinx doc

Karolina Surma 1887a95f51 gh-128341: Use _Py_ABI_SLOT in stdlib modules (#145770)
Rename from _Py_INTERNAL_ABI_SLOT to _Py_ABI_SLOT
and define the macro using _PyABIInfo_DEFAULT.

Use the ABI slot in stdlib extension modules to enable running
a check of ABI version compatibility.

_tkinter, _tracemalloc and readline don't use the slots, hence they need
explicit handling.

The previous `Py_REFCNT(x) == 1` checks can have data races in the free
threaded build. `_PyObject_IsUniquelyReferenced(x)` is a more conservative
check that is safe in the free threaded build and is identical to
`Py_REFCNT(x) == 1` in the default GIL-enabled build.

Brett Simmers c2627d6eea gh-116322: Add Py_mod_gil module slot (#116882)
This PR adds the ability to enable the GIL if it was disabled at
interpreter startup, and modifies the multi-phase module initialization
path to enable the GIL when loading a module, unless that module's spec
includes a slot indicating it can run safely without the GIL.

PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went
with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148.

A warning will be issued up to once per interpreter for the first
GIL-using module that is loaded. If `-v` is given, a shorter message
will be printed to stderr every time a GIL-using module is loaded
(including the first one that issues a warning).
