So in these cases you can break the 78 chars rule. Just put them in one
line. We are just out of luck with keeping it in shape ;)

Not important right now, but just calling it connman_stats might be
simpler and shorter. In theory they are not bound to a service anyway
and we also don't care what you are counting either.

Do we have to really cast here? And if so, please lets use (uint32_t) g_
with the extra space in between.

What is the prefix parameter good for. What else are we storing except
the stats counters?

You are missing some empty lines here before and after each function,
but then also feel free to break the 78 chars rule.

I am really leaning towards calling this ResetCounters().

Cast? Extra space!
