[glib] Convert ifaceproperties.c to test framework

commit 2a5e0cf9e0d67ea35b2f5fdf8bb2297354bcb7e6
Author: Matthias Clasen <mclasen redhat com>
Date:   Mon Dec 27 23:37:21 2010 -0500

    Convert ifaceproperties.c to test framework
    
    Also add a test that checks warnings for failure to implement
    interface properties.
    
    See https://bugzilla.gnome.org/show_bug.cgi?id=637738
