* parser/Gtk.metadata: add a bunch of out arg rules, add
a vararg rule for the ListStore constructor, change method names of
TreeModel's signal emission methods, remove opaque rule of
GtkTreeIter, remove null_ok rules of TreeModel.IterNChildren
and TreeModel.IterNthChild.
* parser/Metadata.pm: add some code to be able to filter on
parameter names.
* generator/Method.cs: a method with accessor args and a non-void
return value cannot be written as property.
* sample/Makefile.in, sample/TreeViewDemo.cs: add a simple TreeView
demo app.
* gtk/ListStore.custom, gtk/TreeModel.custom, gtk/TreeModelSort.custom,
gtk/TreeStore.custom, gtk/TreeView.custom: customizations.
