Move _Py_GetAllocatedBlocks() and _PyObject_DebugMallocStats()
declarations to pycore_pymem.h. These functions are related to memory
allocators, not to the PyObject structure.
This change is a prerequisite for generating code for other global objects (like strings in gh-30928).
(We borrowed some code from Tools/scripts/deepfreeze.py.)

* Substitution with a list of types returns now a tuple of types.
* Substitution with Concatenate returns now a Concatenate with
concatenated lists of arguments.
* Substitution with Ellipsis is not supported.
Less specific number wording (as there is no one right number - the old 100k is too big for some applications and woefully small for others). We now link to NIST SP 800-132 to tell people what to read in there on how to decide for their application.

Revert "bpo-45162: Remove many old deprecated unittest features (GH-28268)"
This reverts commit b0a6ede3d0.
We're deferring this change until 3.12 while upstream projects that use
the legacy assertion method names are fixed. See the issue for links
to the discussion. Many upstream projects now have issues and PRs
filed.
In the File menu, 'Close' and 'Exit' are now 'Close Window' (the current
one) and 'Exit' is now 'Exit IDLE' (by closing all windows).
In Shell, 'quit()' and 'exit()' mean 'close Shell'.
If there are no other windows, this also exits IDLE.
Previously this didn't matter because there weren't any valid code paths
that could trigger a type check with a special form, but after the bug
fix for `Annotated` wrapping special forms it's now possible to annotate
something like `Annotated['ClassVar[int]', (3, 4)]`. This change would
also be needed for proposed future changes, such as allowing `ClassVar`
and `Final` to nest each other in dataclasses.
Convert the PyType_SUPPORTS_WEAKREFS() macro to a regular function.
It no longer access the PyTypeObject.tp_weaklistoffset member
directly.
Add _PyType_SUPPORTS_WEAKREFS() static inline functions, used
internally by Python for best performance.
Since,
- Py_CompileString no longer allows to distinguish "incomplete input"
from "invalid input"
- there is no alternative solution available from the Python C API
due to how the new parser works (rewritten in 3.9)
- the only supported way is to manually import the codeop module from C
and use its API as IDLE does, and accept its own complications
it is desirable to remove this Q&A from the official FAQ.
We treat Annotated type arg as class-level annotation. This exempts it from checks against Final and ClassVar in order to allow using them in any nesting order.
