Datatrak import rework: changes on helper funcs

Browse source 
Remove dtrak_profile() profile parsing func as this work is left to
libdivecomputer.
Simplifies read_file_header() to return the number of dives in the log
file as we don't use the rest of header data.
Add dtrak_prepare_data() to achieve a device_data_t structure and get
the correct libdc model number for the device.
Remove checking macro substituted with JUMP in header file.
Add dt_libdc_buffer() to get a buffer parseable with libdivecomputer.
