Some public key algorithms (like ECDSA) keep in parameters field important data such as digest and curve OIDs (possibly more for different ECDSA variants). Thus, just setting a public key (as for RSA) is not enough. Introduce set_params() callback for akcipher which will be used to pass BER encoded parameters array, with additional argument of algorithm OID. This is done with the intent of adding support for EC-RDSA (ISO/IEC 14888-3:2018, RFC 7091, and basically ECDSA variant) public keys (which will be finally used in IMA subsystem). Thus, also oid_registry.h is updated. Rationale: - For such keys just setting public key without parameters is meaningless, so it would be possible to add parameters in crypto_akcipher_set_pub_key (and .set_pub_key) calls. But, this will needlessly change API for RSA akcipher. Also, additional callback making it possible to pass parameters after crypto_akcipher_set_priv_key (and .set_priv_key) in the future. - Algorithm OID is passed to be validated in .set_params callback, otherwise, it could have the wrong value. - Particular algorithm OIDs are checked in x509_note_params, (because this is called from AlgorithmIdentifier (ASN.1) parser, which is called multiple times, as it's used multiple times in X.509 certificate), to distinguish a public key call from a signature call.
