Secretly reusing my own LRU code

Last week, I secretly reused my own LRU code in the model of the editor of a CNC machine (has truly huge files, needs a statement editor). I rewrote my own code, of course. It’s Qt based, not GLib. Wouldn’t work in original form anyway. But the same principle. Don’t tell J├╝rg who helped me write that, back then.

Extra points and free beer for people who can find it in Tracker’s code.
