d611400897 core: move get_distance() from divesite.cpp to units.cpp
This gives the distance between to location_t objects. It is
unclear why this was in divesite.cpp.

Moreover pass by value, not raw pointer.

No more C source files, no more necessity to use C-linkage.

5128d0ed5f core: convert pref.c and units.c to C++
Convert both files simultanously, because the SI_UNITS define works
either under C or under C++.

This was painful, because initialization of struct-members has to
be done in order of definition in C++. And it was completely out
of order. However, as long as not all is C++, we can't use
default initialization directly in the struct definition. :(
