Modify the signature of the checksum operation in the krb5_checksum_type structure so that it processes iovecs rather than solid blocks of data. Update all of the implementations of these functions for all of the checksum types that we support so that they process iovecs, either by iterating through the iovec in each function, or by calling _krb5_evp_digest_iov or _krb5_evp_hmac_iov() Update callers of these functions so that they turn their single blocks of data into a single iovec of the correct type before calling checksum
