Simplify code related to compilation of SSL and OpenSSL
This commit makes more generic some comments and code related to the compilation with OpenSSL and SSL in general to ease the addition of more SSL implementations in the future. In libpq, some OpenSSL-only code is moved under USE_OPENSSL and not USE_SSL. While on it, make a comment more consistent in libpq-fe.h.
