  Modified files:
    sys/sys              vnode.h 
    sys/kern             vfs_subr.c 
    sys/vm               vm_fault.c 
  Log:
      Final commit to remove vnode->v_lastr.  vm_fault now handles read
      clustering issues (replacing code that used to be in
      ufs/ufs/ufs_readwrite.c).  vm_fault also now uses the new VM page counter
      inlines.
  
      This completes the changeover from vnode->v_lastr to vm_entry_t->v_lastr
      for VM, and fp->f_nextread and fp->f_seqcount (which have been in the
      tree for a while).  Determination of the I/O strategy (sequential, random,
      and so forth) is now handled on a descriptor-by-descriptor basis for
      base I/O calls, and on a memory-region-by-memory-region and
      process-by-process basis for VM faults.
