Pull up following revision(s) (requested by roy in ticket #147):

        sys/netinet/if_arp.c: revision 1.285
        sys/netinet/if_arp.c: revision 1.286

ARP: remove unused sysctl entry log_unknown_network

ARP: change default sysctl entry log_movements to 0
IP address sharing is a thing and shouldn't cause needless diagnostics
by default.
