Support LibreSSL with opaque structures

Determining if OpenSSL structures are opaque now uses an autoconf check
instead of comparing the version number. Some definitions have been
moved to their own check as assumptions which were true for OpenSSL
with opaque structures did not hold for LibreSSL. Closes ticket 21359.
