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.
The latest versions of the Divesoft Freedom (HW 4.x) and Liberty (HW
2.x) dive computers support BLE communication. Previous generations did
support only a mass storage mode, where the dives are available as DLF
files. The BLE communication protocol uses HDLC framing for the data
packets. The dives downloaded over BLE have the same data format as the
DLF files.
