This new method allows getting a widget from a GtkStack when we know its
name, and will also return NULL if there is no widget going by that
name.
Usage example would be to check if a child with a given name exists
before calling gtk_stack_set_visible_child_name().

The GtkStack and GtkStackSwitcher code did not really
follow GTK+ conventions for includes. Fix that, and also
fix up a case of gpointer vs gpointer* confusion
in gtkstack.c.
This adds new 'over' and 'under' transitions which work by moving
the new page over the previous one, or moving the previous page off
to reveal the new one. We also add an over/under combination that
is going to be used in GtkAboutDialog.

Add separate GtkStack and GtkStackSwitcher widgets that are an
alternative to GtkNotebook. Additionally, GtkStack supports
animated transitions when changing pages.
These widgets were initially developed in libgd.
