[Arek] - this one we could change for the following reasons:
- this is TLS specific registry, this values does not need to correspond with other protocols like Ikev2
- we cannot set deprecated values < 19
- TLS registry to some extent is incorrectly named to. It contains mod exp groups as well, and we do not even support that. But if we would, it probably be not "crypto_ec_group"

[Arek] - DH Verify need to be added anyway, but rfc here is because I have split asym_op_type into dh_op_type and asym_op_type. This leaves asym_op_type like that:
{
ENCRYPT,
DECRYPT,
AUTHENTICATE = SIGN,
VERIFY = VERIFY_SIGNATURE,
}
I know it is too late to create one generic op_type for symmetric and asymmetric but still it is better to group crypto and key exchange operations.

[Arek] - unless someone can show how it works we should drop it.

[Arek] - same as above, unless there is any application for it we should drop it.
