  [glib] Drop fallback code for versions we don’t support
  
  We require Glib 2.30.0, so drop checks for older versions.

   * @short_description: GObject integration support
   * @include: hb-gobject.h
   *
   * Support for using HarfBuzz with the GObject library to provide
   * type data.
   *
   * The types and functions listed here are solely a linkage between
   * HarfBuzz's public data types and the GTypes used by the GObject framework.
   * HarfBuzz uses GObject introspection to generate its Python bindings 
   * (and potentially other language bindings); client programs should never need
   * to access the GObject-integration mechanics.
   *
   * For client programs using the GNOME and GTK software stack, please see the
   * GLib and FreeType integration pages.
