base-dirs: add XDG_CONFIG/DATA_DIRS and CONFIGURATION & DATA groups

Browse Source 
This adds support for the system-wide locations for configuration and
data files, as defined by the XDG Base Directory Specification.

In addition, it adds two flag groups, CONFIGURATION and DATA, to the
base-dirs system, so that we don't have to hard-code the combinations
of flags everywhere.
