Update data files for localedef UTF-8 locales from CLDR v2.0.1
There have been fixes in the localedef data files from CLDR -- significant ones as part of v1.9 and minor ones in 1.9.1. We are still using the older v1.8 data. We should update to the newer version.
Note that soon we'll have v2.0, which will be based on Unicode 3.0. I expect that to be a much bigger update.
