- Use namespace CalamaresUtils::Locale consistently for this service.
- Move locale-related non-GUI support code from the Welcome module
to libcalamares; these are generally useful. Both Label (naming a locale)
and LabelModel (managing a bunch of those Labels) have been moved.
- Lookup country data based on enum or 2-letter code
- No data yet, so return only stubs
- The (generated) data tables are not listed as sources because
they are #include'd by the API implementation; they're full of
otherwise-unused static tables, so don't make sense to compile
separately.
- While here, tidy up the CMakeLists a bit to reduce the number
of superfluous variables.
