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.

GH-130397: remove special-casing of C stack depth for WASI (GH-134469)
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.

This was added in the add of `_io`, isn't used since bpo-21859 when a

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.

gh-72680: Fix false positives when using zipfile.is_zipfile() (GH-134250)
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

Extension builders must specify Py_GIL_DISABLED if they want to link to the free-threaded builds.
This was usually the case already, but this change guarantees it in all circumstances.
The 'help("topics")' output was misaligned due to "ASSIGNMENTEXPRESSIONS"
exceeding the implicit maximum default column width of 19 characters.
Reduced the number of columns from 4 to 3 in the listtopics()
function to allow more space for longer topic names.
