Fix thread-safety issues when accessing frame attributes while another
thread is executing the frame:
- Add critical section to frame_repr() to prevent races when accessing
the frame's code object and line number
- Add _Py_NO_SANITIZE_THREAD to PyUnstable_InterpreterFrame_GetLasti()
to allow intentional racy reads of instr_ptr.
- Fix take_ownership() to not write to the original frame's f_executable

gh-143460: Skip infinite recusion tests for infinite stack size (GH-143606)
Avoid tests being killed due to OOM on Linux if a system is configured with
'ulimit -s unlimited' by skipping tests relying on infinite recursion.
While unclear if Python should support 'ulimit -s unlimited', we should at
least try to avoid failing a PGO build running tests due to an unlimited
stack size being set.

gh-139310: skip `test_aead_aes_gcm` for Linux kernel between 6.16.0 and 6.17.x (GH-139552)
Currently, Fedora 42 uses a custom Linux Kernel 6.16.9 that backported an upstream change
from 6.17-rc7 [1,3] but not its subsequent fix [2]. Until the issue is resolved upstream,
we skip the failing test `test_socket.test_aead_aes_gcm` for kernel versions between 6.16
and 6.17.x.

PEP-734 has been accepted (for 3.14).
(FTR, I'm opposed to putting this under the concurrent package, but
doing so is the SC condition under which the module can land in 3.14.)

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.

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.

There's some extra complexity due to making sure we we get things right when handling functions and classes defined in the __main__ module. This is also reflected in the tests, including the addition of extra functions in test.support.import_helper.
Modifies the test helper that counts the list of open file descriptors to use
the optimised ``/dev/fd`` approach on all Apple platforms, not just macOS. This
avoids crashes caused by guarded file descriptors.
This ensures that if we jump through some hoops to make sure something is imported
lazily, we don't regress on importing it.
I recently already accidentally made typing import warnings and annotationlib eagerly.

Make `warnings.catch_warnings()` use a context variable for holding
the warning filtering state if the `sys.flags.context_aware_warnings`
flag is set to true. This makes using the context manager thread-safe in
multi-threaded programs.
Add the `sys.flags.thread_inherit_context` flag. If true, starting a new
thread with `threading.Thread` will use a copy of the context
from the caller of `Thread.start()`.
Both these flags are set to true by default for the free-threaded build
and false for the default build.
Move the Python implementation of warnings.py into _py_warnings.py.
Make _contextvars a builtin module.
