Bug#844303: Working on it porting ncrack to OpenSSL 1.1

[Hilko Bengen]

Control: tag -1 help patch

I have submitted two patches upstream:

(1) https://github.com/nmap/ncrack/pull/34 contains a simple patch for
    opensshlib/configure.ac that sets OPENSSL_API_COMPAT in the various
    test programs, enabling compatibility macros for deprecated function
    names such as SSLeay_version().

(2) https://github.com/nmap/ncrack/pull/35 contains the commit that
    enables building with OpenSSL 1.1, by applying many changes that
    replace direct struct access with getter/setter functions.

Unfortunately, the ncrack sources seem to contain no automated tests.
Any advice on how to test the affected bits of the code is appreciated.

Cheers,
-Hilko
