Support configuring multiple ECDH curves The ssl_ecdh_curve GUC only accepts a single value, but the TLS handshake can list multiple curves in the groups extension (the extension has been renamed to contain more than elliptic curves). This changes the GUC to accept a colon-separated list of curves. This commit also renames the GUC to ssl_groups to match the new nomenclature for the TLS extension.
