java.time Phase 2: Duration/Period, enums, ChronoUnit/Field machinery

Browse source 
Duration (ISO PT.. toString, between, full arithmetic), Period (between with
borrow, P.. toString, normalized), full Month/DayOfWeek enums (named constants,
print as their name — fixes the Phase-1 raw-jhost print), Year, YearMonth
(2020-02 toString, leap, atDay/atEndOfMonth), ChronoUnit (between/getDuration)
and ChronoField. The temporal machinery on the Phase-1 types now works with
ChronoUnit/ChronoField: (.plus t n DAYS), (.until t1 t2 unit), (.get/.getLong
t field), (.with t field v), (.isSupported ..), (.truncatedTo ..).

Analyzer: (. Class method args) with a class target lowers to a static call
(Class/method args) instead of mis-dispatching as an instance call on the arg
— matches JVM; needed by cljc.java-time.year. Seed re-minted; selfhost holds.

The Phase-2 cljc.java-time namespaces load; tick.core advances to a Phase-3
zone gap. 10 corpus rows certified vs JVM. make test + shakesmoke green, 0 new
divergences, data.json stays 138/139.
