gh-100218: correctly set errno when socket.if_{nametoindex,indextoname} raise OSError (#140905) 
Previously, socket.if_nametoindex() and socket.if_indextoname() could raise
an `OSError` with a `None` errno. Now, the errno from libc is propagated.

gh-140815: Fix faulthandler for invalid/freed frame (#140921) 
faulthandler now detects if a frame or a code object is invalid or
freed.

Add helper functions:

* _PyCode_SafeAddr2Line()
* _PyFrame_SafeGetCode()
* _PyFrame_SafeGetLasti()

_PyMem_IsPtrFreed() now detects pointers in [-0xff, 0xff] range
as freed.

gh-131253: free-threaded build support for pystats (gh-137189) 
Allow the --enable-pystats build option to be used with free-threading.  The
stats are now stored on a per-interpreter basis, rather than process global.
For free-threaded builds, the stats structure is allocated per-thread and
then periodically merged into the per-interpreter stats structure (on thread
exit or when the reporting function is called). Most of the pystats related
code has be moved into the file Python/pystats.c.

RDM: Like the change made in a earlier PR to the folder, we can/must use 'maxlen' as a stand in for 'unlimited' when computing line lengths when max_line_length is 0 or None; otherwise the computation results in a traceback.

  E.g., for "/path/to/package/module" try to match with

  "module".
* Ignore trailing "/__init__.py".
* Ignore trailing ".pyw" on Windows.
* Keep matching with the full filename (without optional ".py" extension)
  for compatibility.
* Only ignore the case of the ".py" extension on Windows.
