Berthold Stoeger 317a1c91d4 core: convert dive.c to C++
Long term project: convert core to C++ so that we can
use higer-level constructs, notably std::vector<>.

This does not change any code - only fixes compile issues.

Mostly casting of (void *) to the proper type. Also designated
initialization of the sample struct had to be rearranged.
