Construct a pointer of a specified length to a referencedDataType. Note: It
is preferred to use default sized pointers when possible (i.e., length=-1,
see {@link #PointerDataType(DataType, DataTypeManager)}) instead of
explicitly specifying the pointer length value.

@param referencedDataType data type this pointer points to
@param length             pointer length (-1 will result in dynamically-sized
                          pointer)
@param dtm                associated data type manager whose data
                          organization will be used
