Patch from Denis Vlasenko:
* Do not initialize globals to 0, it is done automatically * unsigned short -> uint16_t, unsigned int -> uint32_t where appropriate (did it ever work on Alphas?) * triple sync() is silly - removed * check_zone_nr uses check_zone_nr2 now * remove trailing periods from messages, uppercase first letter
