Whenever we change directories, we unset the model, and then
we set a new model. This causes several emissions of
GtkTreeSelection::changed, for each of which we do a bunch
of work to update the path bar, the location entry, etc.
We can savely ignore some of these signals, and do less work.
There is no need to animate things when we are just setting up
the startup mode, so disable transitions in the revealer and
the stack. Pointed out by Carlos Soriano
There was some code that lead to the places sidebar loosing track
of the row being dragged if a motion event came in between letting
go of the button and the drag snap-back animation ending. This would
cause us to not show the row again, giving the appearance that it
was 'lost'.

If we don't find Xft values in the X resource db, simply fall
back to the values that are hardcoded in /etc/X11/Xresources
anyway. Extra trickery with likely-made-up screen dimensions
is not going to yield better results, and only makes for a
deeper rabbit hole when debugging.
Support was added for GDK_HINT_ASPECT in
gdk_quartz_window_set_geometry_hints though with one restriction:
min_aspect and max_aspect have to be equal, which I believe corresponds
to the most common usage. A warning will be printed if this condition is
not met but min_aspect will be used anyway.
The menu tracker does a better job of this than we can, so move over to
using it instead.
This fixes issues with './testgmenu --import' not properly displaying
the language submenu.

The current widget lookup code bails out on insensitive widgets, there's
however legit cases where we want DnD handled by a parent of the insensitive
widget, so just keep going upwards in that case.
We also use now the widget state flags, because get_sensitive() doesn't
propagate across hierarchies, so we could conceivably find a drop site
inside an insensitive widget.

This behavior has been made optional on add_popover() time, text handles
will keep being able to overflow the window, in order to allow text
selection on views too close to the window edge.
Regular GtkPopovers are reinstaurated to the previous size positioning
logic though, that is, limited by the visible area of the window.
For now assume that if those flags change for a node, they also changed
for all sibling nodes. This is not strictly true but simplifies
invalidation.
The reason it simplifies invalidation is that when removing or adding a
node, we can just invalidate the first node (for NTH_LAST_CHILD) and the
new node (for NTH_CHILD) and all the other nodes will be invalidated
automatically.
Instead of GTK_CSS_CHANGE_POSITION we now have 4 values:
GTK_CSS_CHANGE_FIRST_CHILD, GTK_CSS_CHANGE_LAST_CHILD,
GTK_CSS_CHANGE_NTH_CHILD and GTK_CSS_CHANGE_NTH_LAST_CHILD
Nobody is using them directly yet.
