Message:
Fix building ngIRCd with OpenSSL 1.1 At the moment, ngIRCd fails to build against OpenSSL 1.1 since the configure check probes for the SSL_library_init symbol which was removed, but probing for a different function availabe in both versions solves that problem: SSL_new(). And as SSL_library_init is no longer needed, the patch boils down to probing SSL_new to assert libssl is available, and disabling the SSL_library_init invokation from OpenSSL 1.1 on, see also another application[1] (NSCA-ng) that did pretty much the same. Patch was compile-tested on both Debian jessie (OpenSSL 1.0.2) and stretch (OpenSSL 1.1). [1] <https://www.nsca-ng.org/cgi-bin/repository/nsca-ng/commit/?id=8afc22031ff174f02caad4afc83fa5dff2c29f8a> (Patch by Christoph, commit message cherry-picked from the email thread on the mailing list by Alex. Thanks!)
