    break.c: Fix compilation against newer GLib versions
    
    G_UNICODE_COMBINING_MARK was renamed as G_UNICODE_SPACING_MARK soon after
    the GLib 2.29.14 release, so fix that in break.c and pango-ot-info.c.
    
    To support GLib on and before 2.29.14, a convenience definition for
    G_UNICODE_SPACING_MARK is defined.
