Subject: [PATCH] SSL legacy support.
Up to now I supported older browsers by supporting older versions of TLS
and cipher suites. I still think it makes sense for my blog, etc. but
not for Nextcloud or GitLab. So here's the first step, make the previous
default SSL configuration be ssl-legacy (split out the common parts to
ssl-common) and next is ssl-modern.
