added try_ssl_size, which handles -1 as error and returns the value otherwise; added RSA private_decrypt and public encrypt

lift_ssl_size

Added public/private encrypt/decrypt to RSA from the original commit + tests; added try_ssl_returns_size macro to check for -1 in case of SSL functions which return size
