Now that OpenSSL 1.1.1 is scarce in the wild, we should start updating the wrappers and stdlib to OpenSSL 3.0 at minimum to make sure tooling using std/net runs without additional packages on most *nix.

It should be safe to drop OpenSSL <1.1.1 support, as those are no longer widely used and does not support the latest TLSv1.3 standard.

We should drop LibreSSL support for now as well, as we don't have the resource to test against that library, and platforms that use LibreSSL also supports OpenSSL.

This is more or less a short term goal to get existing tools running well.
