feat(core): recursive DNS server after Java, measured with Java FILIUS

Browse Source 
The resolver runs on the events now (a query, its dnsQueryTimeout, its
answer at the socket); the blocking resolveDns waits for it, and a
recursive server uses it: its own records, else the zone's name server
from its records, else its own DNS server, else a referral
(DNSServer.answerWithRemoteData).

DnsRun plays five stories on the new dns-recursive network. Measured and
not taken: a server that is its zone's name server asks itself, which asks
itself again, without end (the client times out, then every level floods
its own DNS server); Java guards only the step through its own DNS server.
The core asks itself in neither step. That story is compared up to the
client's query (JAVA_UNTIL).
