  Don't enforce unique device minor number policy anymore.
  
  Except for the case where we use the cloner library (clone_create() and
  friends), there is no reason to enforce a unique device minor number
  policy. There are various drivers in the source tree that allocate unr
  pools and such to provide minor numbers, without using them themselves.
  
  Because we still need to support unique device minor numbers for the
  cloner library, introduce a new flag called D_NEEDMINOR. All cdevsw's
  that are used in combination with the cloner library should be marked
  with this flag to make the cloning work.
  
  This means drivers can now freely use si_drv0 to store their own flags
  and state, making it effectively the same as si_drv1 and si_drv2. We
  still keep the minor() and dev2unit() routines around to make drivers
  happy.
  
  The NTFS code also used the minor number in its hash table. We should
  not do this anymore. If the si_drv0 field would be changed, it would no
  longer end up in the same list.
