TLS is currently implemented over either OpenSSL or GnuTLS, with more backends likely to appear in the future. Currently, those backend libraries are part of the protocol names used during e.g. the configure stage of a build. Hide those details behind a generically-named declaration for the TLS protocol to avoid leaking those details into the configuration stage.
