When a cache contains no fonts, it will be unloaded immediately.
Previously the certain alias and UUID entries will be purged at that time though,
this doesn't work when the targeted directory has sub-directories.
To avoid the unnecessary cache creation with the md5-based naming, try to keep them
as far as possible.
Although this way seems not perfectly working if the first directory to look up is like that
Reject caches when FcPattern isn't a constant.
This is usually unlikely to happen but reported.
I've decided to add more validation since this isn't reproducible
and easy to have a workaround rather than investigating 'why'.

Trying to address what these configuration files really do.
This change allows to see the short description that mention
the purpose of the content in the config file and obtain
them through API.
This change also encourage one who want to make some UI for
the user-specific configuration management. it is the main
purpose of this change for me though.
Aside from that, I've also made programs translatable. so
we see more dependencies on the build time for gettext,
and itstool to generate PO from xml.
Prefer the system provided emoji fonts on systems which provide one,
such as Windows, MacOS and Android, even if the Emoji One or Emoji Two
fonts are installed.
This also allows free software OSes such as GNOME to prefer the Emoji
One font, which is not used in other OSes and therefore has a unique
brand identity, by installing them and only them by default.
Users can use more capable fonts while Emoji One and Emoji Two catch up
by installing a font otherwise already used by another system, such as
Google's freely redistributable Noto Emoji font.
