gh-105587: Remove assertion from `_PyStaticObject_CheckRefcnt` (GH-105638)
(cherry picked from commit 6199fe3b32)
Co-authored-by: Eddie Elizondo <eduardo.elizondorueda@gmail.com>
This fixes a race during import. The existing _PyRuntimeState.imports.pkgcontext is shared between interpreters, and occasionally this would cause a crash when multiple interpreters were importing extensions modules at the same time. To solve this we add a thread-local variable for the value. We also leave the existing state (and infrequent race) in place for platforms that do not support thread-local variables.

gh-105387: Limited C API implements Py_INCREF() as func (GH-105388)

implementation details.

For a while now, pending calls only run in the main thread (in the main interpreter). This PR changes things to allow any thread run a pending call, unless the pending call was explicitly added for the main thread to run.

Miscellaneous improvements to the typing docs (GH-105529)
Mostly, these are changes so that we use shorter sentences and shorter paragraphs. In particular, I've tried to make the first sentence introducing each object in the typing API short and declarative.

* gh-102304: Fix Py_INCREF() for limited C API 3.9 (#105550)
When Python is built in debug mode (Py_REF_DEBUG macro), Py_INCREF()
and Py_DECREF() of the limited C API 3.9 (and older) now call
Py_IncRef() and Py_DecRef(), since _Py_IncRef() and _Py_DecRef() were
added to Python 3.10.
(cherry picked from commit 7ba0fd9f87)
* gh-102304: Remove Py_INCREF() doc change (#105552)
Py_INCREF() was made compatible again with Python 3.9 and older in
the limited API of Python debug mode.
(cherry picked from commit 58e4b69f69)
The risk of a race with this state is relatively low, but we play it safe anyway. We do avoid using the lock in performance-sensitive cases where the risk of a race is very, very low.
