Andy McFadden 19ba34760b Rework ItemContainerGenerator StatusChanged hack 
This is another attempt to fix the ListView keyboard position
behavior.  Basic problem: if you change something in the ListView,
the keyboard position is lost, and WPF doesn't expose a nice way to
save and restore it.  It appears the way to set the position is by
calling Focus() on the specific item you want to have as the "current"
keyboard position, but you can only do that at certain times.

This attempt removes the grid-splitter resize hack, in favor of just
setting a "needs refocus" flag when we restore the selection set.
This causes Focus() to be called from the StatusChanged callback on
the next event with status="containers generated".

During testing I noticed some other odd behavior: if you used "goto"
to jump to an address, up/down arrows would change focus to a
different control (menu items, grid splitters, etc).  The problem
there was that we were setting focus to the ListView control rather
than to a ListViewItem, so arrow keys were in control-traversal mode
rather than list-walk mode.  That is also fixed.

/// <summary>
/// Sets the focus to the ListViewItem identified by SelectedIndex. This must be done
/// after the ListView contents have changed, when the ItemContainerGenerator's
/// StatusChanged event fires.
/// </summary>
/// <remarks>
/// Sample steps to reproduce problem:
/// 1. add or remove a note
/// 2. hit the down-arrow key
///
/// This causes the ListView's contents to change enough that the keyboard position
/// is reset to zero, so attempting to move cursor up or down with an arrow key causes
/// the ListView position to jump to the top of the file. The keyboard navigation
/// appears to be independent of which element(s) are selected.
///
/// The workaround for this is to set the focus to the specific item where you want the
/// keyboard to be after making a change to the list. This isn't quite so simple,
/// because at the point where we're restoring the selection flags, the UI elements
/// haven't yet been generated. We need to wait for a "status changed" event to arrive
/// from the ItemContainerGenerator.
///
/// This: http://cytivrat.blogspot.com/2011/05/selecting-first-item-in-wpf-listview.html
/// formed the basis of my initial solution. The blog post was about a different problem,
/// where you'd have to hit the down-arrow twice after the control was first created
/// because the focus is on the control rather than the item. The same approach applies
/// here as well.
///
/// Unfortunately, grabbing focus like this on every update causes problems with the
/// GridSplitters. As soon as the splitter start to move, the ListView grabs focus and
/// prevents them from moving more than a few pixels. The workaround was to do nothing
/// while the splitters are being moved. This didn't solve the problem completely,
/// e.g. you couldn't move the splitters with the arrow keys by more than one step
/// because the ListView gets a StatusChanged event and steals focus away, but at least the
/// mouse worked. (See issue #52 and https://stackoverflow.com/q/58652064/294248.)
///
/// Unfortunately, this update didn't solve other problems created by the initial solution,
/// because setting the item focus clears multi-select. If you held shift down while
/// hitting down-arrow, things would work fine until you reached the bottom of the
/// screen, at which point the virtual UI stuff would cause the item container generator
/// to do work and change state. (See issue #105.)
///
/// The current approach is to set an explicit "refocus needed" boolean when we make
/// changes to the list, and ignore the "status changed" events in other circumstances.
/// This seems to have the correct behavior (so far).
