gh-143547: Fix PyErr_FormatUnraisable() fallback (#143557)
Hold a strong reference to 'hook' while calling the default
unraisable took to log hook failure.
(cherry picked from commit 39a2bcf949095bd603f7b73f15b5b478dbb49ba9)
PyObject_GetBuffer() can execute user code (e.g. via __buffer__), which may
close or otherwise mutate a BytesIO object while write() or writelines()
is in progress. This could invalidate the internal buffer and lead to a
use-after-free.
Ensure that PyObject_GetBuffer() is called before validation checks.

gh-143429: Use compile-time NaN encoding detection for test_struct (GH-143432)
(cherry picked from commit dcdb23f9db2bd683e5d37558f09b458be25a9b4d)
Co-authored-by: Henry Chen <chenx97@aosc.io>
In optimized and `-Og` builds, arguments and local variables are frequently
unavailable in gdb. This makes `py-bt` fail to print anything useful. Use the
`PyThreadState*` pointers `_Py_tss_gilstate` and `Py_tss_tstate` to find the
interpreter frame if we can't get the frame from the
`_PyEval_EvalFrameDefault` call.

gh-142302: Fix mkstemp() documentation: clarify file descriptor inheritance behavior (GH-142338)
The documentation incorrectly stated that the file descriptor is not
inherited by child processes. In reality, the close-on-exec flag (when
available) only prevents inheritance across exec() calls, not fork().

gh-69686: Remove untrue part of `__import__` replacement docs (GH-143261)
Remove untrue part of `__import__` replacement docs
The original statement effectively says that replacing `__import__` at global scope affects import statements, and not only that, but only import statements within the rest of the executing module. None of that has been true since at least Python 2.7, I think.
This was likely missed in python/cpython#69686.
