  Log:
  The island council met and voted buf_prewrite() home.
  
  Give ffs it's own bufobj->bo_ops vector and create a private strategy
  routine, (currently misnamed for forwards compatibility), which is
  just a copy of the generic bufstrategy routine except we call
  softdep_disk_prewrite() directly instead of through the buf_prewrite()
  indirection.
  
  Teach UFS about the need for softdep_disk_prewrite() and call the
  function directly in FFS.
  
  Remove buf_prewrite() from the default bufstrategy() and from the
  global bio_ops method vector.
