  SVN rev 199209 on 2009-11-12 00:52:14Z by attilio
  
  The building the dev nameunit string, in devclass_add_device() is based
  on the assumption that the unit linked with the device is invariant but
  that can change when calling devclass_alloc_unit() (because -1 is passed
  or, more simply, because the unit choosen is beyond the table limits).
  This results in a completely bogus string building.
  
  Fix this by reserving the necessary room for all the possible characters
  printable by a positive integer (we do not allow for negative unit
  number).
