Move from using critical sections to locks for the (de)compression methods.
Since the methods allow other threads to run, we should use a lock rather
than a critical section.
Removed special-casing for WASI when setting C stack depth limits. Since WASI has its own C stack checking this isn't a security risk.
Also disabled some tests that stopped passing. They all happened to have already been disabled under Emscripten.
The `__main__` module imported in the `_pyrepl` module points to the `_pyrepl` module itself when the interpreter was launched without `-m` option and didn't execute a module,
while it's an unexpected behavior that `__main__` can be `_pyrepl` and relative imports such as `from . import *` works based on the `_pyrepl` module.

Update `test_io` `_check_warn_on_dealloc` to use `self.` to dispatch to
different I/O implementations.
Update the `_pyio` implementation to match expected behavior, using the
same `_dealloc_warn` design as the C implementation uses to report the
topmost `__del__` object.
The FileIO one now matches all the others, so can use IOBase. There was
a missing check on closing (self._fd must be valid), add that check
It now supports a "full" fallback to _PyFunction_GetXIData() and then `_PyPickle_GetXIData()`. There's also room for other fallback modes if that later makes sense.
Switches over to a _Py_thread_local in place of autoTssKey, and also fixes a few other checks regarding PyGILState_Ensure after finalization.
Note that this doesn't fix concurrent use of PyGILState_Ensure with Py_Finalize; I'm pretty sure zapthreads doesn't work at all, and that needs to be fixed seperately.
bpo-28494: Improve zipfile.is_zipfile reliability
The zipfile.is_zipfile function would only search for the EndOfZipfile
section header. This failed to correctly identify non-zipfiles that
contained this header. Now the zipfile.is_zipfile function verifies
the first central directory entry.
Changes:
* Extended zipfile.is_zipfile to verify zipfile catalog
* Added tests to validate failure of binary non-zipfiles
* Reuse 'concat' handling for is_zipfile

* Mention remote debugging via -p PID in usage text
Adds a brief note to the pdb help summary about attaching to a running
process using the -p option, making the remote debugging feature
more visible.
* Mention remote debugging in pdb.rst

* Teach pprint about dict views with PrettyPrinter._pprint_dict_view and ._pprint_dict_items_view.
* Use _private names for _dict_*_view attributes of PrettyPrinter.
* Use explicit 'items' keyword when calling _pprint_dict_view from _pprint_dict_items_view.
* 📜🤖 Added by blurb_it.
* Improve tests
* Add tests for collections.abc.[Keys|Items|Mapping|Values]View support in pprint.
* Add support for collections.abc.[Keys|Items|Mapping|Values]View in pprint.
* Split _pprint_dict_view into _pprint_abc_view, so pretty-printing normal dict views and ABC views is handled in two simple methods.
* Simplify redundant code.
* Add collections.abc views to some existing pprint tests.
* Test that views from collection.UserDict are correctly formatted by pprint.
* Handle recursive dict and ABC views.
* Test that subclasses of ABC views work in pprint.
* Test dict views coming from collections.Counter.
* Test ABC views coming from collections.ChainMap.
* Test odict views coming from collections.OrderedDict.
* Rename _pprint_abc_view to _pprint_mapping_abc_view.
* Add pprint test for mapping ABC views where ._mapping has a custom __repr__ and fix ChainMap test.
* When a mapping ABC view has a ._mapping that defines a custom __repr__, dispatch pretty-printing it by that __repr__.
* Add tests for ABC mapping views subclasses that don't replace __repr__, also handling those that delete ._mapping on instances.
* Simplify the pretty printing of ABC mapping views.
* Add a test for depth handling when pretty printing dict views.
* Fix checking whether the view type is a subclass of an items view, add a test.
* Move construction of the views __repr__ set out of _safe_repr.
