* Make musl test skips smarter (fixes Alpine errors)
A relatively small number of tests fail when the underlying c library is
provided by musl. This was originally reported in bpo-46390 by
Christian Heimes. Among other changes, these tests were marked for
skipping in gh-31947/ef1327e3 as part of bpo-40280 (emscripten support),
but the skips were conditioned on the *platform* being emscripten (or
wasi, skips for which ere added in 9b50585e02).
In gh-131071 Victor Stinner added a linked_to_musl function to enable
skipping a test in test_math that fails under musl, like it does on a
number of other platforms. This check can successfully detect that
python is running under musl on Alpine, which was the original problem
report in bpo-46390.
This PR replaces Victor's solution with an enhancement to
platform.libc_ver that does the check more cheaply, and also gets the
version number. The latter is important because the math test being
skipped is due to a bug in musl that has been fixed, but as of this
checkin date has not yet been released. When it is, the test skip can
be fixed to check for the minimum needed version.
The enhanced version of linked_to_musl is also used to do the skips of
the other tests that generically fail under musl, as opposed to
emscripten or wasi only failures. This will allow these tests to be
skipped automatically on Alpine.
This PR does *not* enhance libc_ver to support emscripten and wasi, as
I'm not familiar with those platforms; instead it returns a version
triple of (0, 0, 0) for those platforms. This means the musl tests will
be skipped regardless of musl version, so ideally someone will add
support to libc_ver for these platforms.
* Platform tests and bug fixes.
In adding tests for the new platform code I found a bug in the old code:
if a valid version is passed for version and it is greater than the
version found for an so *and* there is no glibc version, then the
version from the argument was returned. The code changes here fix
that.
* Add support docs, including for some preexisting is_xxx's.
* Add news item about libc_ver enhancement.
* Prettify platform re expression using re.VERBOSE.
Tools such as ruff can ignore "imported but unused" warnings if a
line ends with "# noqa: F401". It avoids the temptation to remove
an import which is used effectively.
* gh-118673: Remove shebang and executable bits from stdlib modules.
* Removed shebangs and exe bits on turtledemo scripts.
The setting was inappropriate for '__main__' and inconsistent across the other modules. The scripts can still be executed directly by invoking with the desired interpreter.

``platform.architecture()`` now returns the format of binaries (e.g. Mach-O) instead of the default empty string.

The argument is used as a switch and corresponds to a boolean logic. Therefore it is more intuitive to use the corresponding constant `False` as default value instead of the integer `0`.

`os.path.realpath()` already exists in all our supported Python versions.
There's no longer a need to check if it exists or not.

The sys module uses the kernel32.dll version number, which can vary from the "actual" Windows version.
Since the best option for getting the version is WMI (which is expensive), we switch back to launching cmd.exe (which is also expensive, but a lot less code on our part).
sys.getwindowsversion() is not updated to avoid launching executables from that module.

* bpo-42163: Override uname_result._make to allow uname_result._replace to work (for everything but 'processor'.
* Replace hard-coded length with one derived from the definition.
* Add test capturing missed expectation with copy/deepcopy on namedtuple (bpo-42189).
* bpo-42189: Exclude processor parameter when constructing uname_result.
* In _make, rely on __new__ to strip processor.
* Add blurb.
* iter is not necessary here.
* Rely on num_fields in __new__
* Add test for slices on uname
* Add test for copy and pickle.

* Replace flag-flip indirection with direct inspection
* Use any for simpler code
* Avoid flag flip and set results directly.
* Resolve processor in a single function.
* Extract processor handling into a namespace (class)
* Remove _syscmd_uname, unused
* Restore platform.processor behavior to match prior expectation (reliant on uname -p in a subprocess).
* Extract '_unknown_as_blank' function.
* Override uname_result to resolve the processor late.
* Add a test intended to capture the expected values from 'uname -p'
* Instead of trying to keep track of all of the possible outputs on different systems (probably a fool's errand), simply assert that except for the known platform variance, uname().processor matches the output of 'uname -p'
* Use a skipIf directive
* Use contextlib.suppress to suppress the error. Inline strip call.
* 📜🤖 Added by blurb_it.
* Remove use of contextlib.suppress (it would fail with NameError if it had any effect). Rely on _unknown_as_blank to replace unknown with blank.

When libc_ver() is called with an executable, the
os.confstr('CS_GNU_LIBC_VERSION') fast-path cannot be taken. Modify
platform.platform() to call libc_ver() without executable, instead of
calling libc_ver(sys.executable), since sys.executable is already the
default value.
Make platform.architecture() parsing of "file" command output more
reliable:
* Add the "-b" option to the "file" command to omit the filename;
* Force the usage of the C locale;
* Search also the "shared object" pattern.
