<i18n dev> [11u] RFR: 8212970: TZ database in "vanguard" format support

[Langer, Christoph]

Hi,

please review this backport to JDK11 updates:

Bug: https://bugs.openjdk.java.net/browse/JDK-8212970
Webrev: http://cr.openjdk.java.net/~clanger/webrevs/8212970.11u-dev.0/
Original Change: https://hg.openjdk.java.net/jdk/jdk/rev/99d2dd7b84a8

This backport is prerequisite to JDK-8228469: (tz) Upgrade time-zone data to tzdata2019b, which is required for 11.0.5. This will make the JDK's timezone parser support the "vanguard" format and enables a simple backport of JDK-8228469.

To make the patch applicable to jdk11u, I had to manually do all the deletions in  test/jdk/sun/util/calendar/zi/tzdata and test/jdk/sun/util/calendar/zi/tzdata_jdk.

Furthermore there were some rejects which were easy to resolve in:
make/jdk/src/classes/build/tools/tzdb/TzdbZoneRulesCompiler.java -> Copyright year
make/jdk/src/classes/build/tools/tzdb/TzdbZoneRulesProvider.java -> Copyright year and import statements
src/java.base/share/classes/java/time/zone/Ser.java -> Copyright year
src/java.base/share/classes/java/time/zone/ZoneOffsetTransitionRule.java -> Copyright year

With the patch applied all regression testing shows still green (both, jtreg and TCK).

Thanks
Christoph
