Construstor for BinaryDataContainer taking unique_ptr<sal_uInt8> represents a way how to create and fill the data for the container and make sure that the container is the only one that is managing the data after construction. Generally we don't want to give the access to the internal shared_ptr to the outside, so with the unique_ptr we make sure that there is no outside references present (which would be the case if the we would take shared_ptr as the constructor) and the unique_ptr is cleared (moved) after construction.
