[evince/wip/recent-view: 8/10] ev-toolbar: Implement toolbar with multiple modes

[Germán Poó Caamaño <gpoo src gnome org>]

commit 1ea15fd0cf828b1e5d4fd9a5b1b995dcfd6e2088

    ev-toolbar: Implement toolbar with multiple modes
    
    Given the restrictions of GtkHeaderBar for reparenting, we must
    implement multiple modes for the toolbar, which can be customized
    for Recent View, Full Screen, Preview and Document (normal).
    
    For now, Full Screen, Preview and Document are the same.
