*
* Enable key identifiers that encode a key owner identifier.
*
* This is only meaningful when building the library as part of a
* multi-client service. When you activate this option, you must provide an
* implementation of the type mbedtls_key_owner_id_t and a translation from
* mbedtls_svc_key_id_t to file name in all the storage backends that you
* you wish to support.
* The owner of a key is identified by a value of type ::mbedtls_key_owner_id_t
* which is currently hard-coded to be int32_t.
*
* Note that this option is meant for internal use only and may be removed
* without notice.
