A few more pieces of old compatibility code can be dropped, as we
already depend on GLib 2.38.

-/**
- * SECTION:gbinding
- * @Title: GBinding
- * @Short_Description: Bind two object properties
- *
- * #GBinding is the representation of a binding between a property on a
- * #GObject instance (or source) and another property on another #GObject
- * instance (or target). Whenever the source property changes, the same
- * value is applied to the target property; for instance, the following
- * binding:
- *
- * |[
- *   g_object_bind_property (object1, "property-a",
- *                           object2, "property-b",
- *                           G_BINDING_DEFAULT);
- * ]|
- *
- * will cause <emphasis>object2:property-b</emphasis> to be updated every
- * time g_object_set() or the specific accessor changes the value of
- * <emphasis>object1:property-a</emphasis>.
- *
- * It is possible to create a bidirectional binding between two properties
- * of two #GObject instances, so that if either property changes, the
- * other is updated as well, for instance:
- *
- * |[
- *   g_object_bind_property (object1, "property-a",
- *                           object2, "property-b",
- *                           G_BINDING_BIDIRECTIONAL);
- * ]|
- *
- * will keep the two properties in sync.
- *
- * It is also possible to set a custom transformation function (in both
- * directions, in case of a bidirectional binding) to apply a custom
- * transformation from the source value to the target value before
- * applying it; for instance, the following binding:
- *
- * |[
- *   g_object_bind_property_full (adjustment1, "value",
- *                                adjustment2, "value",
- *                                G_BINDING_BIDIRECTIONAL,
- *                                celsius_to_fahrenheit,
- *                                fahrenheit_to_celsius,
- *                                NULL, NULL);
- * ]|
- *
- * will keep the <emphasis>value</emphasis> property of the two adjustments
- * in sync; the <function>celsius_to_fahrenheit</function> function will be
- * called whenever the <emphasis>adjustment1:value</emphasis> property changes
- * and will transform the current value of the property before applying it
- * to the <emphasis>adjustment2:value</emphasis> property; vice versa, the
- * <function>fahrenheit_to_celsius</function> function will be called whenever
- * the <emphasis>adjustment2:value</emphasis> property changes, and will
- * transform the current value of the property before applying it to the
- * <emphasis>adjustment1:value</emphasis>.
- *
- * Note that #GBinding does not resolve cycles by itself; a cycle like
- *
- * |[
- *   object1:propertyA -> object2:propertyB
- *   object2:propertyB -> object3:propertyC
- *   object3:propertyC -> object1:propertyA
- * ]|
- *
- * might lead to an infinite loop. The loop, in this particular case,
- * can be avoided if the objects emit the #GObject::notify signal only
- * if the value has effectively been changed. A binding is implemented
- * using the #GObject::notify signal, so it is susceptible to all the
- * various ways of blocking a signal emission, like g_signal_stop_emission()
- * or g_signal_handler_block().
- *
- * A binding will be severed, and the resources it allocates freed, whenever
- * either one of the #GObject instances it refers to are finalized, or when
- * the #GBinding instance loses its last reference.
- *
- * #GBinding is available since GObject 2.26
