Re: OpenSSL 3.0 for 14.0-RELEASE: issues with 1.x/3.x symbol clashing, ports linking against base OpenSSL, ports that don't compile/link against OpenSSL 3, etc

This is my view.  I think making OpenSSL private is a very huge task, and
fraught with peril in ways that haven't been thought about yet (e.g. PAM)
and that we can't hold up OpenSSL 3 while we wait for this.  Instead, I think
we need to be moving forward with OpenSSL 3 in base as-is.  We will have to
fix ports to work with OpenSSL 3 regardless (though this does make that pain
in ports happen sooner).  Moving libraries private can happen orthogonally
with getting base to work with OpensSL 3.
