Drop ot_{byte,word,dword} and use uint{8,16,32}_t, also move run time keeping and FULLSCRAPE stderr output to ot_stats

Finally split up the opentracker.c cruft into ot_http.c, ot_accesslist.c and just leave in socket handling and parameter parsing

Encforce setting the clock more often. This hopefully fixes a rare bug of g_now not being updated anymore.

Completely rewritten fullscrape code. All assumptions on how deflate() works were a little naive. Needs more error checking and testing.
