Ticket40138: Better autoconf warning on openssl version mismatch

This branch adds an autoconf check for version mismatch between openssl includes and headers. If it finds one, it tells the user what options it tried to use, and suggests the --with-openssl-dir option.

Additionally, it counts the number of times we gave a warning, and summarizes that number at the end of the configure script, in case the user missed any of them.
