Need a function to perform UTS35 3.3.1 BCP 47 Language Tag to Unicode BCP 47 Locale Identifier
Description
Currently there are no code to perform the UTS35 3.3.1 BCP 47 Language Tag to Unicode BCP 47 Locale Identifier canonicalization as stated in
http://unicode.org/reports/tr35/#Language_Tag_to_Locale_Identifier
Since the implementation need to read in resource from "metadata", we should add a new class to implement such canonicalization.
See
icu4j/tools/misc/src/com/ibm/icu/dev/tool/locale/LikelySubtagsBuilder.java
icu4j/main/classes/core/src/com/ibm/icu/util/Region.java
icu4c/source/i18n/region.cpp
for examples of how to read the "replacement" from metadata/alias/{language,territory}

I think it should be a different class (eg LocaleCanonicalizer), not just a different method. Doesn't make a big difference in C++ perhaps, but in Java we can avoid pulling in code/data with ULocale that might not be used.

I have code that does most of the canonicalization; can clean it up and apply it.
not too hard except we need some clarification of the UTS.
I have prototyped the Java one and half way on the C++ one.

Looking forward to a concrete proposal
ok, my prototypes with both C++ and Java are in my branch
Java Test
C++ interface
C++ code
C++ test
Still need to add C one. Stay tune. Will send in a proposal tomorrow.
