[gtk+] Use GSlice for GtkRequisition

[Javier Jardón <jjardon src gnome org>]

commit eaab96c066b550445df1883b2fe8728d61f42b99
Author: Javier Jardón <jjardon gnome org>
Date:   Tue May 4 05:27:50 2010 +0200

    Use GSlice for GtkRequisition
    
    Also add gtk_requisition_new to avoid memory allocator confusions when
    using GtkRequisitions.
    
    Based on a Christian Persch patch.
    Fixes https://bugzilla.gnome.org/show_bug.cgi?id=461618
