       OSSL_CMP_HDR_get0_transactionID returns the transaction ID of the given PKIHeader.

       OSSL_CMP_HDR_get0_recipNonce returns the recipient nonce of the given PKIHeader.

       OSSL_CMP_HDR_get0_geninfo_ITAVs() returns the list of ITAVs in the generalInfo field of the given
       PKIHeader.

       The OpenSSL CMP support was added in OpenSSL 3.0.

       OSSL_CMP_HDR_get0_geninfo_ITAVs() was added in OpenSSL 3.3.

       functions manipulating CMP message headers

       CMP is defined in RFC 4210.

       The functions return the intended pointer value as described above or NULL if the respective entry does
       not exist and on error.
