    entry: Do not clobber state when rendering the default icons.
    
    Use lower level methods that just require changing the state in the
    GtkStyleContext instead. Fixes a problem where the insensitive state
    was being set to the entry becasuse a parent was insensitive, spotted
    by Alex Larsson.
