  This is a conversion table from old parameter values to new
  parameter names. The startup code looks for saved values of the old
  parameters and will copy them across to the new parameters if the
  new parameter does not yet have a saved value. It then saves the new
  value.

  Note that this works even if the old parameter has been removed. It
  relies on the old k_param index not being removed

  The second column below is the index in the var_info[] table for the
  old object. This should be zero for top level parameters.
