/**
   @param info
       The expected target type. Currently info is provdided when this method is called
       to convert the in/out and out parameters of a call from cli to uno. Then info
       is always a byref type, e.g. "System.String&". info is used for Any and Enum conversion.
   @param bDontCreateObj
       false - a new object is created which holds the mapped uno value and is assigned to
       cli_data.
       true - cli_data already contains the newly constructed object. This is the case if
       a struct is converted then on the first call to map_to_cli the new object is created.
       If the struct inherits another struct then this function is called recursivly while the
       newly created object is passed in cli_data.
