Add gtk_list_box_prepend

Add a convenience method for prepending rows to a list box without
having to fiddle with a sort function.

https://bugzilla.gnome.org/show_bug.cgi?id=705558
examples: Use git.mk
gtkiconhelper: Add _gtk_icon_helper_ensure_surface to private header
gdk_pixbuf_get_from_surface: Avoid copying if source is image surface

If the source surface is an image surface we don't need to coerce
it to one.
gdk: Add gdk_cursor_get_surface()

We want a surface so we can properly represent the scale factor for it.
All backends are converted to use surfaces and we reimplement the
backwards compat code in the generic code.
gdk: Add gdk_cursor_new_from_surface

We need this to be able to handle scaled cursor images.
We implement the new _from_pixbuf by converting to a surface and
assuming the scale was 1.
gtkdnd: Use surface based cursor APIs

This allows things to correctly scale things on HiDPI screens.
headerbar: use a more standard headerbar look for the close button

gtkstylecontext: Remove some dead code when rendering layouts
gtkdnd: Clean up the doc comment of gtk_drag_begin
gtkiconview: Remove the border and background from drag icons

This doesn't look good when combined with rounded corners on
selected items.

gtkiconview: Take padding into account when getting the cursor hotspot

This makes the icon view look completely seamless when dragging.

listbox: Implement gtk_list_box_insert()

... to make it possible to insert rows in the middle of the list without having
to fiddle with the sort functions. One of the first users is going to be Glade.

listbox: Reorder code

This just moves the gtk_list_box_insert function to where the rest of the
public API is defined.
