uloc_forLanguageTag has a few mapping tables to map grandfathered
language tags and deprecated language subtags to their preferred or
modern values.
Update them based on the latest version of the IANA
language subtag registry. [1]
Five grandfathered tags without a preferred value are still mapped to
what ICU has mapped them to for backward compatibility until the
wisdom of continuing to do so is reviewed.
In addition, map redundant language tags to their preferred values
regardless of whether they're followed by other subtags or not. (e.g.
zh-yue vs zh-yue-u-co-pinyin) .
Similary, ja-latn-hepburn-heploc is mapped to ja-latn-alaic97 (the
variant subtag 'hepburn-helploc' with the prefix 'ja-latn' has the
preferred value, 'alaic97') .
Update the mapping for deprecated language subtags (e.g. 'jw' to
'jv' and a bunch of 3-letter language codes).
Add a new table for deprecated region subtags to map them to their
modern values. (e.g. 'DD' to 'DE').
Add a new test case for deprecated language and region mapping and
a few more cases for updated grandfathered and redundant tag mapping.

* ICU-20119 Update and fixes for the following BRS tasks:
- Update urename.h
- Test uconfig.h variations
* ICU-20119 Updates copyright scanner script exclusions: don't scan ./git/*.
* ICU-20119 Changes in reply to comments for pull requst #165.
* Fix MSVC C4251: Need to export explicit template instantiation for std::atomic<int32_t> when building DLLs
* Some more warning fixes for MSVC as well.
* Can't use static_cast in C file.
- name the travis build steps
- copy cpyskip.txt to /.cpyskip.txt
- add one named "lint" which runs cpyscan.pl
- remove network access from Cpy.pm (requires installation)
This gets rid of those fixed buffers that caused ICU-13417 to be filed
in the first place, those that prevent handling language tags with very
large amounts of keywords.
A number of fixed buffers will still remain in uloc_tag.cpp (and
elsewhere in the locale handling code) for the time being, but this
change is a necessary first step in cleaning up this code and will
alleviate the most pressing problem encountered by ICU4C users.
An off-by-one error in _getKeywords() caused uloc_canonicalize() to not
write out the final keyword value in case the result would fill up the
buffer exactly, resulting in U_STRING_NOT_TERMINATED_WARNING.
- Updated API status of java.lang.Object method overrides (equals/hashCode/toString/clone) to match status of declaring class. There are some API comments that is insufficient, or incorrect, or not appropriate after the change. Most of these issues were fixed.
- APIStatusConsistencyChecker and ant tasks invoking the check, designed for checking this requirement. For now, Normalizer#clone() does not satisfy the requirement, but unchanged on purpose. The tool can accept exception.
- DeprecatedAPIChecker had a problem for handling non-static inner class's constructor. CodePointMap$StringIterator is the very first instance of such class in ICU4J. The problem was fixed by removing the implicit param scanned by reflection.
- This commit includes a lot of changes made by Eclipse project configuration - removing spaces in blank lines/end of statement, and removeal of redundant generics type declaration.
In an effort to reduce the number of warnings that building ICU emits, we should set the following define for ICU4C library code when building using MSVC/VisualStudio: _HAS_EXCEPTIONS=0
This tells the MSVC implementation of the STL that exceptions should not be used - which is fine for ICU4C library code, as the library code does not make use of exceptions at all.
- Use stack allocated UResouceBundle to reduce number of calls to malloc (in a method that can't report back an error if Out-Of-Memory [OOM] happens).
- Use LocalUResourcePointer for automatic clean-up of UResouceBundle.
- Use uprv_strdup instead of calloc + strcpy.
- Changes comments, formatting, etc.
