gh-104399: Use newer libtommath APIs when necessary (GH-104407)
(cherry picked from commit 00d73caf80)

Upgrade builds to OpenSSL 1.1.1u.
This OpenSSL version addresses a pile if less-urgent CVEs since 1.1.1t.
The Mac/BuildScript/build-installer.py was already updated.
Also updates _ssl_data_111.h from OpenSSL 1.1.1u, _ssl_data_300.h from 3.0.9.
Manual edits to the _ssl_data_300.h file prevent it from removing any existing definitions in case those exist in some peoples builds and were important (avoiding regressions during backporting).

Move all of the Python C API calls into the parent process up front
instead of doing PyLong_AsLong and PyErr_Occurred and PyTuple_GET from
the post-fork/vfork child process.
Much of this was long overdue. We shouldn't have been using PyTuple and
PyLong APIs within all of these low level functions anyways.
This is a backport of c649df6 for #104518 and the tiny adjustment in d1732fe#104697.
Backporting this allows backporting of the real bug fix that requires it.

gh-101857: Allow xattr detection on musl libc (GH-101858)
Previously, we checked exclusively for `__GLIBC__` (AND'd with some other
conditions). Checking for `__linux__` instead should be fine.
This fixes using e.g. `os.listxattr()` on systems using musl libc.

Fix Zip64 extensions not being properly applied in some cases:
Fixes an issue where adding a small file to a `ZipFile`
object while forcing zip64 extensions causes an extra Zip64 record to be
added to the zip, but doesn't update the `min_version` or file sizes in
the primary central directory header.
Also fixed an edge case in checking if zip64 extensions are required:
This fixes an issue where if data requiring zip64 extensions was added
to an unseekable stream without specifying `force_zip64=True`, zip64
extensions would not be used and a RuntimeError would not be raised when
closing the file (even though the size would be known at that point).
This would result in successfully writing corrupt zip files.
Deciding if zip64 extensions are required outside of the `FileHeader`
function means that both `FileHeader` and `_ZipWriteFile` will always be
in sync. Previously, the `FileHeader` function could enable zip64
extensions without propagating that decision to the `_ZipWriteFile`
class, which would then not correctly write the data descriptor record
or check for errors on close.
If anyone is actually using `ZipInfo.FileHeader` as a public API without
explicitly passing True or False in for zip64, their own code may still be
susceptible to that kind of bug unless they make a similar change to
where the zip64 decision happens.
Fixes GH-103861

gh-87474: Fix file descriptor leaks in subprocess.Popen (GH-96351)
This fixes several ways file descriptors could be leaked from `subprocess.Popen` constructor during error conditions by opening them later and using a context manager "fds to close" registration scheme to ensure they get closed before returning.
