listview: Add GtkListItemManager It's all stubs for now, but here's the basic ideas about what this object is supposed to do: (1) It's supposed to be handling all the child GtkWidgets that are used by the listview, so that the listview can concern itself with how many items it needs and where to put them. (2) It's meant to do the caching of widgets that are not (currently) used. (3) It's meant to track items that remain in the model across items-changed emissions and just change position. (2) It's code that can be shared between listview and potential other widgets like a GridView. It's also free to assume that the number of items it's supposed to manage doesn't grow too much, so it's free to use O(N) algorithms.

listitem: Make this a GObject This splits GtkListItem into 2 parts: 1. GtkListItem This is purely a GObject with public API for developers who want to populate lists. There is no chance to cause conflict with GtkWidget properties that the list implementation assumed control over and defines a clear boundary. 2. GtkListItemWidget The widget part of the listitem. This is not only fully in control of the list machinery, the machinery can also use different widget implementations for different list widgets like I inted to for GtkColumnView.
