Extracted from the GnuTLS thread/patch, here is a patch to add a
server-side read-only parameter ssl_library, which currently reports
either 'OpenSSL' or an empty string, depending on what SSL library was
built with. This is analogous to the libpq function call
PQsslAttribute(conn, "library"), but there was no equivalent
functionality on the server side.
