* \brief Set the allowed curves in order of preference.
*
* On server: this only affects selection of the ECDHE curve;
* the curves used for ECDH and ECDSA are determined by the
* list of available certificates instead.
*
* On client: this affects the list of curves offered for any
* use. The server can override our preference order.
*
* Both sides: limits the set of curves accepted for use in
* ECDHE and in the peer's end-entity certificate.
*
* \deprecated Superseded by mbedtls_ssl_conf_groups().
*
* \note This has no influence on which curves are allowed inside the
* certificate chains, see \c mbedtls_ssl_conf_cert_profile()
* for that. For the end-entity certificate however, the key
* will be accepted only if it is allowed both by this list
* and by the cert profile.
*
* \note This list should be ordered by decreasing preference
* (preferred curve first).
*
* \note The default list is the same set of curves that
* #mbedtls_x509_crt_profile_default allows, plus
* ECDHE-only curves selected according to the same criteria.
* The order favors curves with the lowest resource usage.
*
* \note New minor versions of Mbed TLS may extend this list,
* for example if new curves are added to the library.
* New minor versions of Mbed TLS will not remove items
* from this list unless serious security concerns require it.
* New minor versions of Mbed TLS may change the order in
* keeping with the general principle of favoring the lowest
* resource usage.
*
* \param conf SSL configuration
* \param curves Ordered list of allowed curves,
* terminated by MBEDTLS_ECP_DP_NONE.
