Bug: https://bugs.openjdk.java.net/browse/JDK-8202088
Webrev: https://cr.openjdk.java.net/~andrew/openjdk7/8202088/webrev.01/

This is the backport of the Japanese new era placeholder implementation
to OpenJDK 7u. It is significantly smaller than the versions for 8u &
11u, as 7u does not contain the java.time.* API and is also not subject
to the maintenance review [0] which adds the new code point support in

What remains is the addition of the new era to the Japanese imperial
calendar implementation. Although this lives in java.util, the class is
package-private so there is no API change.

The remaining elements applied largely as is, with some whitespace
adjustments and differing copyright notices. The new tests were altered
to work around the lack of Calendar.Builder in OpenJDK 7.

Both new tests fail on the unpatched codebase with an
ArrayIndexOutOfBoundsException and pass on the patched version.

The second @run line is also removed from JapaneseEraNameTest.java as
OpenJDK 7 does not have multiple locale providers.
