feat(core): the command line's network commands ping, host, nslookup, arp and netstat after Java, measured against Java

Browse Source 
TerminalRun types lines into Java's command line on terminal-net at set
times; the engine types the same lines. New in the engine: an ICMP echo
in a program's thread (the first ICMP message after the send, whatever
it is), Java's route choice, the ARP table with Java's broadcast row, DNS
in a program's thread, ICMP broadcasts of a node's own network, and an
ARP wait that ends after what else happens at that millisecond.

Departures from Java: an echo is answered from the address asked
(RFC 792), network unreachable carries the packet with its sender, ping
names the host and takes only -b before it, arp and netstat list in the
order learned, netstat lists a UDP server's listening socket only.
