Add GtkListBase This is a base item for GTK's list widgets so they can share some (read: hopefully a lot of) code.

listbase: Move item manager here Nothing really changes, because both ListView and GridView still keep self->item_manager around, but it's set up to point at the base's item manager. This way we can slowly move things to GtkListBase that need the item manager (like trackers).

listbase: Compute rubberband region on-demand Instead of storing the active items as we go, compute the affected items whenever the rubberband changes and in particular when the rubberband ends. That way, the rubberband is guaranteed to select a rectangle even after scrolling very far. This is achieved by having a get_items_in_rect() vfunc that selects all the items in the rubberbanded rectangle and returns them as a bitset.

wip: Add GtkCoverFlow The widget mostly works out of the box, but some tweaking may be necessary (in particular in the theme) and the gtk-demo changes might require removing before this is production-ready.
