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.
The warning is not intended to disable the Create button and must only be shown
when the folder is not found, so this is implemented in the folder name exists
callback.
A "name" entry was added to FileExistsData to pass the filename to the callback

Allow the name and location columns to be resized, but arrange
for their sizing to be reset when the column layout changes (either
by the location column appearing/disappearing, or by the time
column changing between mtime and atime. This gives a decent
compromise between good automatic sizing and user control.
The code for getting the selected files was assuming that
we are always in browse mode, and was causing warnings when
hitting Ctrl-L twice, right after opening the file chooser.
The fix is to simple use the model that is passed into the
callback.
Avoid reloading models unnecessarily, e.g. when the user
switches to search and back without starting a search.
Keep the current list contents visible until a search is
actually started. Also, synchronize any changes in the
column layout with the corresponding model changes.
