[gtk+/wip/csoriano/pathbar-prototype: 68/68] Implement new GtkPathBar



commit 323049ba319c2bba2d5aa660ef787565e7b592e7
Author: Carlos Soriano <csoriano gnome org>
Date:   Thu Oct 22 20:15:34 2015 +0200

    Implement new GtkPathBar
    
    Following mockups and rewritting it completly to be able
    to be used by other projects like gnome-builder and dconf-editor
    and sanitize its code.
    This GtkPathBar will be only "visual", so no file management is done,
    and instead a subclass GtkFilesPathBar in a following patch will
    implement file management for the use case of GtkFileChooser and Nautilus.

#NULL in the case of a @selected_volume.
+   * @selected_volume: (type Gio.Volume) (nullable): #GVolume if the selected item is a volume, or #NULL if

+   *
+   * The places sidebar emits this signal when the user invokes a contextual
+   * popup on one of its items. In the signal handler, the application may
+   * add extra items to the menu as appropriate. For example, a file manager
+   * may want to add a "Properties" command to the menu.
+   *
+   * It is not necessary to store the @selected_item for each menu item;
+   * during their callbacks, the application can use gtk_places_sidebar_get_location()
+   * to get the file to which the item refers.
+   *
+   * The @selected_item argument may be %NULL in case the selection refers to
+   * a volume. In this case, @selected_volume will be non-%NULL. In this case,
+   * the calling application will have to g_object_ref() the @selected_volume and
+   * keep it around to use it in the callback.
+   *
+   * The @container and all its contents are destroyed after the user
+   * dismisses the popup. The popup is re-created (and thus, this signal is
+   * emitted) every time the user activates the contextual menu.
+   *
+   * Before 3.18, the @container always was a #GtkMenu, and you were expected
+   * to add your items as #GtkMenuItems. Since 3.18, the popup may be implemented
+   * as a #GtkPopover, in which case @container will be something else, e.g. a
+   * #GtkBox, to which you may add #GtkModelButtons or other widgets, such as
