    kernel - Add cluster_readcb()
    
    * This function is similar to breadcb() in that it issues the requested
      buffer I/O asynchronously with a callback, but then also clusters
      additional asynchronous I/Os (without a callback) to improve performance.
    
    * Used by HAMMER2 to improve performance.
