giant cleanups/rewrites which are unnoticeable to users: 

*client->server renamed client->host_server to clarify ambiguity
*ecore_con_ssl_client_prepare.* killed off because it was useless and wrong
*openssl generates only one SSL_CTX per server now instead of a new one for each client, which is broken/unnecessary/wasteful
**as a result, certificate loading is now only done once
**additionally this will save a very large amount of memory and avoid unnecessary/broken refcounting
*ecore_con_ssl_server_prepare.* rewritten to actually be useful instead of just a lazy way to null pointers
**all SSL_CTX code now goes here^
*some formatting fixes
*internal function renames
