gh-105699: Use a _Py_hashtable_t for the PyModuleDef Cache (gh-106974)
This fixes a crasher due to a race condition, triggered infrequently when two isolated (own GIL) subinterpreters simultaneously initialize their sys or builtins modules. The crash happened due the combination of the "detached" thread state we were using and the "last holder" logic we use for the GIL. It turns out it's tricky to use the same thread state for different threads. Who could have guessed?
We solve the problem by eliminating the one object we were still sharing between interpreters. We replace it with a low-level hashtable, using the "raw" allocator to avoid tying it to the main interpreter.
We also remove the accommodations for "detached" thread states, which were a dubious idea to start with.

(cherry picked from commit c0b81c4b54)
Co-authored-by: Eric Snow <ericsnowcurrently@gmail.com>
Declare the following functions as macros, since they are actually
macros. It avoids a warning on "TYPE" or "macro" argument.
* PyMem_New()
* PyMem_Resize()
* PyModule_AddIntMacro()
* PyModule_AddStringMacro()
* PyObject_GC_New()
* PyObject_GC_NewVar()
* PyObject_New()
* PyObject_NewVar()
Add C standard C types to nitpick_ignore in Doc/conf.py:
* int64_t
* uint64_t
* uintptr_t
No longer ignore non existing "__int" type in nitpick_ignore.
Update Doc/tools/.nitignore.

gh-104432: Use `memcpy()` to avoid misaligned loads (GH-104433)
Fix potential unaligned memory access on C APIs involving returned sequences
of `char *` pointers within the :mod:`grp` and :mod:`socket` modules. These
were revealed using a ``-fsaniziter=alignment`` build on ARM macOS.

gh-105699: Disable the Interpreters Stress Tests (gh-107354)
The two tests are crashing periodically in CI and on buildbots. I suspect the problem is in the _xxsubinterpreters module.
Regardless, I'm disabling the tests temporarily, to reduce the noise as we approach 3.12rc1. I'll be investigating the crashes separately.
(cherry picked from commit 4f67921ad2)
Co-authored-by: Eric Snow <ericsnowcurrently@gmail.com>
The _xxsubinterpreters module was meant to only use public API. Some internal C-API usage snuck in over the last few years (e.g. gh-28969). This fixes that.

gh-106948: Update documentation nitpick_ignore for c:identifer domain (GH-107295)
Update the nitpick_ignore of the documentation configuration to fix
Sphinx warnings about standard C types when declaring functions with
the "c:function" markups.
Copy standard C types declared in the "c:type" domain to the
"c:identifier" domain, since "c:function" markup looks for types in
the "c:identifier" domain.
