Since the DHT doesn't take a stride argument, I'd recommend using a
either plain array or a gsl_block to avoid any confusion if there are
vectors with non-unit stride (otherwise, check that stride==1).

It is fine to access the data as x->data, the struct is part of the
public interface and will not change.  Also, it's clearer to read that
way in my opinion.
