Berthold Stoeger cf7c54bd56 core: turn a memblock in the parser to std::string
This avoid memory-management troubles. Had to convert a few
of the parsers (cochran, datatrak, liquivision) to C++.
Also had to convert libdivecomputer.c. This was less
painful than expected.

std::string is used because parts of the code assumes
that the data is null terminated after the last character
of the data. std::string does precisely that.

One disadvantage is that std::string clears its memory
when resizing / initializing. Thus we read the file onto
freshly cleared data, which some might thing is a
performance regression. Until someone shows me that this
matters, I don't care.
