These functions are prerequisites for implementing EVP_PKEY_todata(). OSSL_PARAM_dup() is required to make a deep copy of the exported params (since the provider export() uses a OSSL_PARAM_BLD which throws away the data after the call), and then use OSSL_PARAM_merge() to add some additional params that can be passed to the EVP_PKEY_todata().
