Subject: [PATCH 15/26] port-to-gtk3: Use Gtk::CellLayout::get_cells() (#7)

GParted uses Gtk::TreeViewColumn::get_cell_renderers().  This is not
present in Gtkmm3.  Now Gtk::TreeViewColumn inherits from
Gtk::CellLayout and we have to use Gtk::CellLayout::get_cells() instead.

GtkCellLayout was introduced in Gtk2 version 2.18 as the common
interface for containers of cell renderers.

The C++ wrapper Gtk::CellLayout was introduced in Gtkmm2 version 2.18,
but Gtk::TreeViewColumn was never made to inherit from Gtk::CellLayout
to avoid breaking the API / ABI.  That change was made for Gtkmm3.

This is an excerpt from gtkmm/treeviewcolumn.h header in Gtkmm2:
  // TODO: Should be deprecated, but we cannot derive from CellLayout
  // without breaking API and ABI.

  /** Returns a list of all the cell renderers in the column,
   * in no particular order.
   *
   * @return A list of Gtk::CellRenderers.
   */
  Glib::ListHandle<CellRenderer*> get_cell_renderers();

Replace Gtk::TreeViewColumn::get_cell_renderers() with base class
method Gtk::CellLayout::get_cells().
