Qt: Refactor the packet list scroll bar.

Split OverlayScrollBar into parent and child scroll bar widgets. This
gives us two packet list scroll bars: a packet map, which draws and
operates on nearby packets and a normal scroll bar.

The packet map is drawn to the left of the child scroll bar. This gives
us more room to draw and doesn't obscure the scroll bar itself (which is
a problem on newer versions of Windows). When the user clicks on a
portion of the map, scroll to that part of the packet list.

Draw marked packet ticks over the normal scroll bar. Marked & ignored
are on the left, time references are on the right.

To do:

- Borrow more from packet fence and graph something (packet size? time
  delta?)
