Implement smarter locale resource selection
* Add support for determining script from language and region.
* Add support for determining special parents of locales.
* Add support for smart comparison of locales with only a difference
in region, using the locale parentage tree.
* Fix LocaleData.matchScore() to not fallback to old locale matching
behavior if we can't determine a script.
* Allow four-character variant codes. (Previously, only five- to
eight-character variant codes were allowed.)
