Subject: [PATCH] Remove no longer working links from docs

The links to explanations of SSL concept at hpe.com were no longer
working and redirected to the OpenVMS main documentation set. The
EVComp FAQ has been lost in a site reorg, and IBM no longer provide
an online documentation for AIX 6.1. Fix by removing the now stale
links,
