* ICU-20140 Allow duplicated keys in U-extension per RFC 6067
RFC 6067 [1] does allow duplicate keywords, but ICU4C's
uloc_forLanguageCode rejects it as invalid.
Change it to accept duplicate keywords and honor only the
1st one while ignoring subsequent ones per RFC 6067.
[1] Unicode extension to BCP 47:
https://tools.ietf.org/html/rfc6067
* ICU-20140 Add ICU4J test and tweak ICU4C test
ICU4J test diverges from ICU4C tests:
1. Handling of duplicate variants in ICU4J seem to be wrong:
https://unicode-org.atlassian.net/browse/ICU-20148
2. ULocale.forLanguageTag only throws NullPointException so
that ICU4C's test for duplicate attributes cannot be ported.
- Follow the spec to calculate the mimimum significant digits in engineering notation
- The bug is regression since ICU 58. The new test still passes on
ICU58-based DecimalFormat
- Maximum significant digits is not changed
* Updated era data format in supplementalData.
* Include tentative era names in data. Implemented Japanese era loaded from CLDR data in ICU4J.
* ICU4C implementation, ICU4C refactoring. WIP.
* VS project updates and some bug fixes
Also added API comments.
* Review feedback and bug fixes
- NULL to nullptr
- use of LocalUResourceBundlePointer
- TYPO "name" to "named"
- env var checking stricmp() == 0
* API comment correction based on feedback
* Duplicate the comment in ucal.h to calendar.h
* Fixed spelling errors in API comment
* ICU-20098 Fix the validty check for extlang in uloc_forLanguageTag
BCP 47 has the following for language. extlang subtag can only be
preceded by 2*3ALPHA. Add a check for the length of language subtag
before extlang subtag.
language = 2*3ALPHA ; shortest ISO 639 code
["-" extlang] ; sometimes followed by
; extended language subtags
/ 4ALPHA ; or reserved for future use
/ 5*8ALPHA ; or registered language subtag
extlang = 3ALPHA ; selected ISO 639 codes
*2("-" 3ALPHA) ; permanently reserved}}
With this change, 'hant-cmn-CN' would drop '-cmn-CN' keeping only
'hant'.
* ICU-20098 Fix the validty check for extlang for ICU4J
* ICU-20098 Fix the compiler failure for ICU4J
* ICU-20098 Fix a compile error and test.
* ICU-20098 Add a test for invalid private use singleton
ICU4C's check for private use singleton subtag ('x') is wrong and
treats invalid language tags as valid.
ICU4J's check is correct and does not require any change.
Fix that and add tests to both ICU4C and ICU4J.
By extracting this test case into a separate class and separating the
complex and time consuming building of the UnicodeSet disorderedMarks
data structure into an @BeforeClass shared setup method it becomes
possible to test the 18 different transliteration rules as a
parameterized test case.
This will lower the running time per test case and also aid in debugging
as it will make it immediately obvious which transliteration rules cause
test failures (and which don't).
When running in Android, java.util.TimeZone.getDefault() will only
return a TimeZone object for a time zone that actually exists, so when
passing a bogus test TimeZone object to setDefault() and afterwards
calling getDefault() it won't return that same time zone.
Changing our tests to instead use a real existing (but otherwise unused)
time zone instead makes the tests work in Android as well.
Neither of these tests was testing the ability to set an arbitrarily
made up time zone as the default, so no test coverage is lost.
* ICU-13530 test & fix cptrie.getRange() when small null data block matches the start of a non-null fast data block
* ICU-13530 fix test bug
* ICU-13530 test & fix bug calculating worst-case data array capacity at start of compaction
* ICU-13530 docs: clarify buildImmutable() discards upper bits, trie then returns unsigned ints; range iteration slower than if ranges were stored directly
* ICU-13530 accept feedback on docs
Different implementations of BigDecimal.stripTrailingZeros(), in
different versions of the JDK (and different versions of Android), have
differences in their handling of zero. To avoid this, ICU4J can return
BigDecimal.ZERO for any value that is equal to zero, instead of calling
BigDecimal.stripTrailingZeros() in this problematic case.

Simplified redundant code and removed unnecessary code path for Java 7 and later runtime in various places. Also cleaned up stale comments.
There is one test code change in com.ibm.icu.dev.test.localespi.NumberFormatTest - number keyword in test case was changed to Arab to arab. This test case was skipped with Java 6 runtime. It looks this code was note tested on Java 7 and later. @number=Arab does not work because it's case sensitive and must be all lower case letters.
Previously, ULocale had to work on Java 6, therefore, Java 7 specific Locale methods needed to be invoked by reflection. For the next release, we can directly call Java 7 Locale APIs, so rather complicated reflection implementation were replaced with simple API calls.
Previously, some developers accidentally introduced Java 7 Objects class utility methods. At that time, we once added Java 6 compatible implementation in com.ibm.icu.impl.Utility class. Now, we use Java 7 as the minimum supported Java version, so we can use Java 7 Objects class and methods.
There are some extra changes dropping generics type from constructor. For example from `ArrayList<String> output = new ArrayList<String>();` to `ArrayList<String> output = new ArrayList<>();`. The updated syntax is allowed since Java 7. We have eclipse project configured to normalize such expression, therefore, files touched by this commit were automatically updated. These changes are not directly related to Java 7 Objects method replacement.
Includes all line break tailorings.
Corresponding updates to monkey test rules.
State table builder, fix missed table optimization, uncovered by new rule.
