This applies the proper CSS child ordering semantics using GtkCssNode to
GtkListBox. You can now use :first-child, :last-child, :nth-child(), and
:last-nth-child() selectors.
For example, this allows styling row separators using CSS while ignoring
the separator on the last row.
GtkListBoxRow {
border-bottom: 1px solid @borders;
}
GtkListBoxRow:last-child {
border-bottom: none;
}
When the sort ordering of the listbox changes, we also update the CSS
node ordering.
As it is, GtkListBox model binding will work nicely as long as your
create_widget_func returns a floating reference on the newly-created
widget.
If you try to return a full reference (as any higher-level language
would do) then you will leak that reference.
Fix that up by converting any floating references into full references
and then unconditionally releasing the full reference after adding to
the box.

Although gtk_list_box_row_grab_focus() is not a public function
it can be easily called by gtk_widget_grab_focus() with a row argument
which has been removed from the list box and has box == NULL.

gtk_list_box_bind_model() binds a GListModel to a GtkListBox.
This is a first step towards having GListModel support in Gtk. It's not
useful for large models, because GtkListBox always creates all widgets
for all rows.
Rows are not necessarily selected via select_row_internal(), add
the missing signal emissions there. Also the signal should be emitted
when removing the selection altogether.

We now apply the .button style class to rows that are either
activatable or selectable. Selectable rows only get the .button
if the listbox allows selection. This implies that we need to
update row styles when the selection mode changes, or when the
row gets added to a listbox.
Having an explicit property for this will make it easier
to have a hover style only for rows which are activatable
or selectable.
Rows are selectable by default, to preserve compatibility.
The listbox code relies on the container focus adjustment handling
to scroll the cursor row on screen. But GtkContainer has no idea
about row headers, so ensure that we scroll the header on screen too.
This will let us theme activatable rows differently.
We also avoid emitting the ::row-activated signal for
rows that are not activatable. For compatibility reasons,
rows are activatable by default.

This commit adds API for dealing with multi-selection. It is identical
to the flow box API for this purpose. The implementation is still limited
to single-selection, and will be updated in subsequent commits.
The button press/release handlers did invariably return FALSE, even
though it shouldn't if a row was found on the event coordinates. Also,
use GDK_EVENT_* defines for the return values.
The 'direction' parameter to gtk_widget_keynav_failed() is based on
gtk_list_box_move_cursor()'s 'count' parameter. However if the passed
in movement is GTK_MOVEMENT_DISPLAY_LINES, 'count' is modified by
the keynav handling and will always be 0. To avoid messing up the
'direction' parameter, use a local variable for keynav handling and
leave 'count' untouched.
