bump glib to 2.38.2
rebump app-mics/geoclue-2.0

geoclue has been completly rewritten and now should belong to gnome.
it's a mandatory dependence of g-c-c, gnome-maps and gnome-clocks.
three new use flags: gebug server and demo are suggested. old ones are
removed. as suggested by upstream geoclue service should not be started
under root, therefore a geoclue group and user are created.
