[gobject-introspection] Fix g_type_info_is_pointer() for overriden types of arguments.

[Pavel Holejsovsky <pholejs src gnome org>]

commit 9e903476ea20e0bc3593816b932eae6b0afd0f2e
Author: Pavel Holejsovsky <pholejs src gnome org>
Date:   Mon Sep 12 19:54:39 2011 +0200

    Fix g_type_info_is_pointer() for overriden types of arguments.
    
    Algorithm which detects whether argument type is pointer checks for
    trailing '*' characters in c:type .gir elements.  This failed if ctype
    is either 'gpointer' or 'gconstpointer'.  Add specific check for
    gpointer/gconstpointer types when deducing pointerness of the type.
