Cleanup: fix include weirdness concerning string_to_*() functions

The string_to_*() functions were declared in dive.h and qthelper.h.
Moreover in one file they were declared with C in the other with
C++ linkage. This only works because qthelper.h includes dive.h
first.

Fix this anomaly by declaring the functions only in qthelper.h,
but moving them from the C++ to the C part.
