gh-76785: Improved Subinterpreters Compatibility with 3.12 (gh-115424)
For the most part, these changes make is substantially easier to backport subinterpreter-related code to 3.12, especially the related modules (e.g. _xxsubinterpreters). The main motivation is to support releasing a PyPI package with the 3.13 capabilities compiled for 3.12.

A lot of the changes here involve either hiding details behind macros/functions or splitting up some files.

gh-76785: More Fixes for test.support.interpreters (gh-113012)
This brings the module (along with the associated extension modules) mostly in sync with PEP 734.  There are only a few small things to wrap up.

gh-76785: Fixes for test.support.interpreters (gh-112982)

gh-76785: Move the Cross-Interpreter Code to Its Own File (gh-111502)
This is partly to clear this stuff out of pystate.c, but also in preparation for moving some code out of _xxsubinterpretersmodule.c.  This change also moves this stuff to the internal API (new: Include/internal/pycore_crossinterp.h).  @vstinner did this previously and I undid it.  Now I'm re-doing it. :/

gh-76785: Make interpreters.*Channel Objects Shareable (gh-110607)
This restores their shareability, which was disabled by gh-110318 due to ref leaks.

gh-84570: Send-Wait Fixes for _xxinterpchannels (gh-111006)
There were a few things I did in gh-110565 that need to be fixed. I also forgot to add tests in that PR.

(Note that this PR exposes a refleak introduced by gh-110246. I'll take care of that separately.)

gh-84570: Implement Waiting in SendChannel.send() (gh-110565)
We had been faking it (poorly).

We will add timeouts separately.

gh-76785: Module-level Fixes for test.support.interpreters (gh-110236)

gh-76785: Use Pending Calls When Releasing Cross-Interpreter Data (gh-109556)
This fixes some crashes in the _xxinterpchannels module, due to a race between interpreters.

gh-108511: Add C API functions which do not silently ignore errors (GH-109025)
Add the following functions:

* PyMapping_HasKeyStringWithError()

gh-101524: Only Use Public C-API in the _xxsubinterpreters Module (gh-107359)
The _xxsubinterpreters module should not rely on internal API.  Some of the functions it uses were recently moved there however.  Here we move them back (and expose them properly).

gh-106320: Remove private _PyInterpreterID C API (#107053)
Move the private _PyInterpreterID C API to the internal C API: add a
new pycore_interp_id.h header file.

Remove Include/interpreteridobject.h and
Include/cpython/interpreteridobject.h header files.

gh-106320: Remove private pylifecycle.h functions (#106400)
Remove private pylifecycle.h functions: move them to the internal C
API ( pycore_atexit.h, pycore_pylifecycle.h and pycore_signal.h). No
longer export most of these functions.

Move _testcapi.test_atexit() to _testinternalcapi.

gh-101524: Only Use Public C-API in the _xxsubinterpreters Module (gh-105258)
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-99113: Add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED (gh-104205)
Here we are doing no more than adding the value for Py_mod_multiple_interpreters and using it for stdlib modules.  We will start checking for it in gh-104206 (once PyInterpreterState.ceval.own_gil is added in gh-104204).

gh-101659: Add _Py_AtExit() (gh-103298)
The function is like Py_AtExit() but for a single interpreter.  This is a companion to the atexit module's register() function, taking a C callback instead of a Python one.

We also update the _xxinterpchannels module to use _Py_AtExit(), which is the motivating case.  (This is inspired by pain points felt while working on gh-101660.)

gh-101659: Use the Raw Allocator in the _xxinterpchannels Module (gh-103287)
Using the raw allocator for any of the global state makes sense, especially as we move to a per-interpreter obmalloc state (gh-101660).

gh-101609: Fix "‘state’ may be used uninitialized" warning in `_xxinterpchannelsmodule` (GH-101610)
I went with the easiest solution: just removing the offending line. See the issue description with my reasoning.

gh-101524: Split Up the _xxsubinterpreters Module (gh-101526)
This is step 1 in potentially dropping all the "channel"-related code. Channels have already been removed from PEP 554.
