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.

* bpo-46504: faster code for trial quotient in x_divrem()
This brings x_divrem() back into synch with x_divrem1(), which was changed
in bpo-46406 to generate faster code to find machine-word division
quotients and remainders. Modern processors compute both with a single
machine instruction, but convincing C to exploit that requires writing
_less_ "clever" C code.
When configuring the logging stack, accept already built filters (or
just callables) in the filters array of loggers and handlers.
This facilitates passing quick callables as filters.

Add the following info to test.pythoninfo:
* windows.ver: output of the shell "ver" command
* windows.version and windows.version_caption: output of the
"wmic os get Caption,Version /value" command.
Add _PyUnicode_FiniTypes() function, called by
finalize_interp_types(). It clears these static types:
* EncodingMapType
* PyFieldNameIter_Type
* PyFormatterIter_Type
_PyStaticType_Dealloc() now does nothing if tp_subclasses
is not NULL.
Add 'static_exceptions' list to factorize code between
_PyExc_InitTypes() and _PyBuiltins_AddExceptions().
_PyExc_InitTypes() does nothing if it's not the main interpreter.
Sort exceptions in Lib/test/exception_hierarchy.txt.
Skip the 3 slowest tests of the Address Sanitizer CI of GitHub
Actions:
* test_tools
* test_peg_generator
* test_concurrent_futures
These tests take between 5 and 20 minutes on this CI which makes this
CI job the slowest. Making this CI job faster makes the whole Python
workflow faster. These tests are run on all others CIs.
Example of Address Sanitizer output:
10 slowest tests:
- test_peg_generator: 17 min 33 sec
- test_tools: 8 min 27 sec
- test_concurrent_futures: 5 min 24 sec
- test_zipfile: 2 min 41 sec
- test_compileall: 2 min 21 sec
- test_asyncio: 2 min 17 sec
- test_gdb: 1 min 43 sec
- test_weakref: 1 min 35 sec
- test_pickle: 1 min 18 sec
- test_subprocess: 1 min 12 sec
Moreover, test_concurrent_futures also seems to be affected by
bpo-45200 bug: libasan dead lock in pthread_create().
* Add comment to recurse_down_subclasses() explaining why it's safe
to use a borrowed reference to tp_subclasses.
* remove_all_subclasses() no longer accept NULL cases
* type_set_bases() now relies on the fact that new_bases is not NULL.
* type_dealloc_common() avoids PyErr_Fetch/PyErr_Restore if tp_bases
is NULL.
* remove_all_subclasses() makes sure that no exception is raised.
* Don't test at runtime if tp_mro only contains types: rely on
_PyType_CAST() assertion for that.
* _PyStaticType_Dealloc() no longer clears tp_subclasses which is
already NULL.
* mro_hierarchy() avoids calling _PyType_GetSubclasses() if
tp_subclasses is NULL.
Coding style:
* Use Py_NewRef().
* Add braces and move variable declarations to the first variable
assignement.
* Rename a few variables and parameters to use better names.
* Move PyContext static types into object.c static_types list.
* Rename PyContextTokenMissing_Type to _PyContextTokenMissing_Type
and declare it in pycore_context.h.
* _PyHamtItems types are no long exported: replace PyAPI_DATA() with
extern.
