* \param ctx Context to be set up
* \param f_rng RNG callback function
* \param p_rng RNG callback context
* \param cipher AEAD cipher to use for ticket protection, eg
* MBEDTLS_CIPHER_AES_256_GCM or MBEDTLS_CIPHER_AES_256_CCM.
* \param cipher AEAD cipher to use for ticket protection.
* Recommended value: MBEDTLS_CIPHER_AES_256_GCM.
* \param lifetime Tickets lifetime in seconds
* Recommended value: 86400 (one day).
*
* \note It is highly recommended to select a cipher that is at
* least as strong as the the strongest ciphersuite
* supported. Usually that means a 256-bit key.
*
* \note The lifetime of the keys is twice the lifetime of tickets.
* It is recommended to pick a reasonnable lifetime so as not
* to negate the benefits of forward secrecy.
*
* \return 0 if successful,
* or a specific MBEDTLS_ERR_XXX error code
