    kernel - Remove dsched
    
    * After consultation, remove dsched from the kernel.  The original idea
      is still valid but the current implementation has had lingering bugs for
      several years now and we've determined that it's just got its fingers into
      too many structures.
    
      Also, the implementation was designed before SSDs, and doesn't play well
      with SSDs.
    
    * Leave various empty entry points in so we can revisit at some
      future date.
