Example of further errors once the two CRYPTO_set_XXXX functions are commented

> Key: GUACAMOLE-205
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-205
> Project: Guacamole
> Issue Type: Bug
> Components: guacamole-server, SSH
> Affects Versions: 0.9.11-incubating
> Environment: Linux 4.9.0-1-686-pae #1 SMP Debian 4.9.2-2 (2017-01-12)
> i686 GNU/Linux
> Reporter: Mark Goldey
>
> There are a number of changes in OpenSSL 1.1 which break compatibility with
> older versions of the API, and which break the Guacamole build if OpenSSL 1.1
> is present, particularly the removal of threading callbacks (replaced with
> no-op macros) and the migration to opaque structures with public accessor
> functions. The error below is due to the no-op macros, and fixing those
> reveals further errors due to the new and required public accessor functions.
> A rough list is here:
> https://wiki.openssl.org/index.php/1.1_API_Changes
> The Guacamole build will need to be updated to take these changes into
> account. The original issue report:
