The dc_parser_set_data() function allows to re-use a parser object for multiple dives. The advantages of this feature are actually very limited in practice. The reduction in memory consumption is almost negligible, because the amount of internal state in the parser is typically very small. But the implementation requires some additional complexity because each backend needs code to reset its internal state. Therefore, the function is removed and the data and size needs to be passed directly to the dc_parser_new() and dc_parser_new2() functions instead. Because keeping a reference to the data has also caused issues in the past, especially for applications implemented in a garbage collected language, the data will now also get copied internally.
