Explicitly handle the case where stdout=STDOUT
as otherwise the existing error handling gets
confused and reports hard to understand errors.

Change old space bit of young objects from 0 to gcstate->visited_space.
This ensures that any object created *and* collected during cycle GC has the bit set correctly.
Python 3.10 changed from using SSL_write() and SSL_read() to SSL_write_ex() and
SSL_read_ex(), but did not update handling of the return value.
Change error handling so that the return value is not examined.
OSError (not EOF) is now returned when retval is 0.
According to *recent* man pages of all functions for which we call
PySSL_SetError, (in OpenSSL 3.0 and 1.1.1), their return value should
be used to determine whether an error happened (i.e. if PySSL_SetError
should be called), but not what kind of error happened (so,
PySSL_SetError shouldn't need retval). To get the error,
we need to use SSL_get_error.

This fixes XML unittest fallout from the https://github.com/python/cpython/issues/115398 security fix. When configured using `--with-system-expat` on systems with older pre 2.6.0 versions of libexpat, our unittests were failing.
* sax|etree: Simplify Expat version guard where simplifiable
Idea by Matěj Cepl
* sax|etree: Fix reparse deferral tests for vanilla Expat <2.6.0
This *does not fix* the case of distros with an older version of libexpat with the 2.6.0 feature backported as a security fix. (Ubuntu is a known example of this with its libexpat1 2.5.0-2ubunutu0.1 package)
Instead of calling `exec()` once for each function added to a dataclass, only call `exec()` once per dataclass. This can lead to speed improvements of up to 20%.
pythongh-112571: allow using fish venv activation script on windows
The fish shell can be used on windows under cygwin or msys2.
This change moves the script to the common folder
so the venv module will install it on both posix and nt systems (like the bash script).

Use support.infinite_recursion() in test_recursive_pickle() of
test_functools to prevent a stack overflow on "ARM64 Windows
Non-Debug" buildbot.
Lower Py_C_RECURSION_LIMIT to 1,000 frames on Windows ARM64.
* GH-113171: Fix "private" (really non-global) IP address ranges
The _private_networks variables, used by various is_private
implementations, were missing some ranges and at the same time had
overly strict ranges (where there are more specific ranges considered
globally reachable by the IANA registries).
This patch updates the ranges with what was missing or otherwise
incorrect.
I left 100.64.0.0/10 alone, for now, as it's been made special in [1]
and I'm not sure if we want to undo that as I don't quite understand the
motivation behind it.
The _address_exclude_many() call returns 8 networks for IPv4, 121
networks for IPv6.

Rewrote binarysort() for clarity.
Also changed the signature to be more coherent (it was mixing sortslice with raw pointers).
No change in method or functionality. However, I left some experiments in, disabled for now
via `#if` tricks. Since this code was first written, some kinds of comparisons have gotten
enormously faster (like for lists of floats), which changes the tradeoffs.
For example, plain insertion sort's simpler innermost loop and highly predictable branches
leave it very competitive (even beating, by a bit) binary insertion when comparisons are
very cheap, despite that it can do many more compares. And it wins big on runs that
are already sorted (moving the next one in takes only 1 compare then).
So I left code for a plain insertion sort, to make future experimenting easier.
Also made the maximum value of minrun a `#define` (``MAX_MINRUN`) to make
experimenting with that easier too.
And another bit of `#if``-disabled code rewrites binary insertion's innermost loop to
remove its unpredictable branch. Surprisingly, this doesn't really seem to help
overall. I'm unclear on why not. It certainly adds more instructions, but they're very
simple, and it's hard to be believe they cost as much as a branch miss.
When I added _PyInterpreterState_IsRunningMain() and friends last year, I tried to accommodate applications that embed Python but don't call _PyInterpreterState_SetRunningMain() (not that they're expected to). That mostly worked fine until my recent changes in gh-117049, where the subtleties with the fallback code led to failures; the change ended up breaking test_tools.test_freeze, which exercises a basic embedding situation.
The simplest fix is to drop the fallback code I originally added to _PyInterpreterState_IsRunningMain() (and later to _PyThreadState_IsRunningMain()). I've kept the fallback in the _xxsubinterpreters module though. I've also updated Py_FrozenMain() to call _PyInterpreterState_SetRunningMain().
