Subject: [PATCH 04/12] keyboard: Get default input sources from gnome-desktop
Right now, we figure out the default input sources ourselves,
based on the current locale and layout information coming from
localed.
This logic needs to be duplicated in several components, so its
now provided by gnome-desktop.
This commit changes it over to use gnome-desktop APIs.
The same time if leverages a gnome-desktop API to fix a bug
where cyrillic layouts were getting added without a latin
counterpart.

- *
- * An important limitation here is that there is no system-wide
- * configuration for input methods, so if the best choice for the
- * language is an input method, we will only find it from the
- * gnome-desktop lookup. But if both sources give us keyboard layouts,
- * we want to prefer the one that's configured system-wide over the one
- * from gnome-desktop.
- *
- * So we first do the gnome-desktop lookup, and keep track of what we
- * got.
- *
- * - If we got an input method, we preselect that, and we're done.
- * - If we got a keyboard layout, and there's no system-wide keyboard
- * layout set, we preselect the layout we got from gnome-desktop.
- * - If we didn't get an input method from gnome-desktop and there
- * is a system-wide keyboard layout set, we preselect that.
