gh-105927: PyImport_AddModule() uses _PyWeakref_GET_REF() (#106001) 
It now raises an exception if sys.modules doesn't hold a strong
reference to the module.

Elaborate the comment explaining why a weak reference is used to
create a borrowed reference.

gh-105927: Avoid calling PyWeakref_GET_OBJECT() (#105997) 
* Replace PyWeakref_GET_OBJECT() with _PyWeakref_GET_REF().
* _sqlite/blob.c now holds a strong reference to the blob object
  while calling close_blob().
* _xidregistry_find_type() now holds a strong reference to registered
  while using it.

gh-105922: Refactor PyRun_InteractiveOneObjectEx() (#105925) 
Refactor PyRun_InteractiveOneObjectEx(), _PyRun_SimpleFileObject()
and PyRun_SimpleStringFlags():

* Keep a strong reference to the __main__ module while using its
  dictionary (PyModule_GetDict()). Use PyImport_AddModule() with
  Py_XNewRef().
* Declare variables closer to where they are defined.
* Rename variables to use name longer than 1 character.
* Add pyrun_one_parse_ast() sub-function.

gh-105699: Use a Thread-Local Variable for PKGCONTEXT (gh-105740) 
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-104812: Run Pending Calls in any Thread (gh-104813) 
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.

gh-100227: Lock Around Modification of the Global Allocators State (gh-105516) 
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.
