Adjust the tests for the `pathlib.types` module so that they can be run
against the `pathlib-abc` PyPI package, which is a backport of the module
for older Python versions.
Specifically, we add a `.support.is_pypi` switch that is false in the
stdlib and true in the pathlib-abc package. This controls which package
we import, and whether or not we run tests against `PurePath` and `Path`.
For compatibility with older Python versions, we stop using
`zipfile.ZipFile.mkdir()` and `zipfile.ZipInfo._for_archive()`.
The subinterpreter tests have data races (see gh-129824).
TSAN attempts to intercept some of the fatal signals, which can lead to
bogus reports. We could possibly handle these via TSAN_OPTIONS, but it's
simpler to just skip those tests -- they're not multithreaded anyways.
Call `urllib.request.pathname2url()` from `pathlib.Path.as_uri()`, and
deprecate the duplicate implementation in `PurePath`.

Deprecate the `nturl2path` module. Its functionality is merged into
`urllib.request`.
Add `tests.test_nturl2path` to exercise `nturl2path`, as it's no longer
covered by `test_urllib`.
* 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.
Closes#130914: Make graphlib.TopologicalSorter.prepare() idempotent
Relax the rules so that `.prepare()` can be called multiple times, provided that no work has been passed out by `.get_ready()` yet.
Email generators using email.policy.default may convert an RFC 2047
encoded-word to unencoded form during header refolding. In a structured
header, this could allow 'specials' chars outside a quoted-string,
leading to invalid address headers and enabling spoofing. This change
ensures a parsed encoded-word that contains specials is kept as an
encoded-word while the header is refolded.

New features:
* refactor `hashlib_helper.requires_hashdigest` in prevision of a future
`hashlib_helper.requires_builtin_hashdigest` for built-in hashes only
* add `hashlib_helper.requires_openssl_hashdigest` to request OpenSSL
hashes, assuming that `_hashlib` exists.
Refactoring:
* split hmac.copy() test by implementation
* update how algorithms are discovered for RFC test cases
* simplify how OpenSSL hash digests are requested
* refactor hexdigest tests for RFC test vectors
* typo fix: `assert_hmac_hexdigest_by_new` -> `assert_hmac_hexdigest_by_name`
Improvements:
* strengthen contract on `hmac_new_by_name` and `hmac_digest_by_name`
* rename mixin classes to better match their responsibility
Remove the `test.test_pathlib.test_pathlib_abc` test module, which was
hollowed out in previous commits. Its few remaining tests are most relevant
to `PurePath` and `Path`, so we move them into `test_pathlib`.
