locales: Add "common.UTF-8" locale See previous commit message. This locale is en_US.UTF-8 with a new LC_CTYPE that covers all common charactersets (not the full UTF-8, but a very good chunk of it). This LC_CTYPE source file is manually created, unfortunately, so it can slowly rot if not updated. Other locales can use the versatile support of UTF-8 by setting LC_CTYPE to "common.UTF-8" in the environment.
Import generated locales (time, money, msg, numeric) All the definitions were generated by the "new" tool located at src/tools/tools/locale. It uses CLDR version 2.0.1 and Unicode release 8.0.0. The tool is smart enough to eliminate duplicates -- every one of these real files is unique. The makefiles are also generated and are much simpler.
