Update locale data for ICU 3.8:...

Update locale data for ICU 3.8:

1. Add the minimal subset of locale data for 35 locales we list in the Accept-Language UI menu for which we have CLDR/ICU data (see issue 2078, 2776)
2. Apply urgent locale fixes for Korean, Catalan, Hungarian, Turkish and 9 Indian languges.
3. Remove the unihan collation table from data/coll/root.txt to cut down the raw data size by over 300kB.

This will be followed by icudt38.dll update for Windows. For Mac and Linux icudata files will not be updated because the trunk will use ICU 4.2 very soon.

TEST=Chrome builds fine and pass all the tests.
