gh-126631: gh-137996: fix pre-loading of `__main__`

gh-118981: multiprocessing.popen_spawn_posix, fix potential hang (gh-118982)
fix potential hang.
It can happen that the child crashes right in the beginning for whatever reason. In this case, the parent will hang when writing into the pipe, because the child fd is not closed yet.
The normal pattern is to close the child fds right after the child proc is forked/executed/spawned, so when the child dies, then also the pipes will be closed, and there will be no hang (the parent gets SIGPIPE instead).

[3.13] gh-138158: Use the `"data"` tarfile extraction filter in `Tools/ssl/multissltests.py` (GH-138147) (#138263)
gh-138158: Use the `"data"` tarfile extraction filter in `Tools/ssl/multissltests.py` (GH-138147)
The `Tools/ssl/multissltests.py` script may extract a possibly untrusted tarball.
Since the script does not necessarily use Python 3.14 or later (where the `"data"`
filter became the default `tarfile` extraction filter), the user may theoretically
suffer from a path traversal attack.
Although the script should not be used in production and usually relies on downloading
trusted sources, the `"data"` extraction filter is now explicitly used wherever relevant.

[3.13] gh-135261: bring back CI job for testing OpenSSL 1.1.1w (GH-135262) (#138110)
This partially reverts commit ad944b5e1f304be1a8c2cc03e9f15005bcb97108
by bringing back the CI job for testing OpenSSL 1.1.1w. Despite this
version being upstream EOL, the rationale for keeping it as follows:
- It most resembles other 1.1.1-work-a-like ssl APIs supported by important vendors.
- Python officially requires OpenSSL 1.1.1 or later, although OpenSSL 3.0 or later
is recommended for cryptographic modules. Since changing the build requirements
requires a transition period, we need to keep testing the allowed versions.
- The code base still contains calls to OpenSSL functions that are deprecated since
OpenSSL 3.0 as well as `ifdef` blocks constrained to OpenSSL 1.1.1.
