libraries are supported. Starting now, each underlying SSL library support code does a set of defines for the 16 functions the generic layer (sslgen.c) uses (all these new function defines use the prefix "curlssl_"). This greatly simplified the generic layer in readability by involving much less #ifdefs and other preprocessor stuff and should make it easier for people to make libcurl work with new SSL libraries. Hopefully I can later on document these 16 functions somewhat as well. I also made most of the internal SSL-dependent functions (using Curl_ssl_ prefix) #defined to nothing when no SSL support is requested - previously they would unnecessarily call mostly empty functions.
