Similarly to the previous commit, it is not only about using the new API. I also make sure we do not assume that parasite data is nul-terminated. In many places, we were just assuming so because these were supposed to be parasite our code set. Yet these are data input contained in files which can be wrong for any reason (corrupted file, bugs, other scripts/plug-ins editing these parasites…). So instead of assuming string parasites are always correctly formatted, I make sure they are nul-terminated by passing them through g_strndup() when necessary.
