9d04b4dd06 Redo child property handling; now we generate classes to hold
the
        child properties for a given widget in a container, and generate
        the child properties as properties on those classes.
        
        * parser/gapi2xml.pl (addPropElem): don't prepend "child_" to
        child prop names any more

        * generator/ClassBase.cs (ClassBase): keep childprops separate
        from properties
        (GenChildProperties): create a subclass of Gtk.ContainerChild
        containing the container type's child properties, and override
the
        Container indexer to return that type.

        * generator/ObjectGen.cs (Generate): call GenChildProperties

        * generator/Property.cs:
        * generator/ChildProperty.cs: Simplify these a bunch, since
        * child
        properties are now represented as C# properties as well. Also
add
        [GLib.Property(cname)] and [Gtk.ChildProperty(cname)]
attributes.

        * glib/Makefile.am (sources): add PropertyAttribute.cs

        * glib/PropertyAttribute.cs: attribute used to label
        GObject properties

        * gtk/Makefile.am (sources): add ChildPropertyAttribute.cs

        * gtk/gtk-api.raw: regenerate for parser changes (remove
        "Child"/"child_" from child property names).

        * gtk/ChildPropertyAttribute.cs: attribute used to label
        GtkContainer child properties

        * gtk/Container.custom: define the ContainerChild class, and an
        indexer to return instances of it.

        * doc/en/Gtk/: update for container child property change

598f8e28e5 * glib/Value.cs: add new constructors for enum and boxed values
that take the name of the type rather than an object/property
        name pair; this way they work for both GObject properties and
        GtkContainer child properties.

        * glib/glue/value.c (gtksharp_value_create_from_type_name): glue
        for that

        * glib/Opaque.cs (GetOpaque): Fix this.

        * generator/Property.cs (Generate): Use the new GLib.Value
        constructors. (Fixes setting of enum-valued child properties.)

e1dc10e4c8 * glib/Object.cs (CreateNativeObject): virtualize
(Object(GType)): Mark this ctor Obsolete

	* gtk/Gtk.metadata: disable the generated GType ctor on Gtk.Widget

	* gtk/Widget.custom (Widget, CreateNativeObject,
	Widget_ParentSet): Connect to our own ParentSet event from
	CreateNativeObject and the GType ctor, and keep a static Hashtable
	of parented widgets, so that adding a managed widget to a
	container keeps both the GObject and the managed object alive.

	* generator/ObjectGen.cs (GenCtors): handle the disable_gtype_ctor
	flag. Also, mark GType ctors [Obsolete]

	* generator/Makefile.am (sources): add ChildProperty.cs

	* generator/ClassBase.cs: handle "childprop" nodes by creating
	ChildProperty objects.

	* glib/Value.cs (explicit operator EnumWrapper): use
	g_value_get_flags() rather than g_value_get_enum() when
	appropriate.

	* glib/glue/value.c (glibsharp_value_holds_flags): glue for that

	* gtk/gtk-api.raw: regen to pick up child properties

	* gtk/Gtk.metadata:

	Gtk.Container.ChildGetProperty and implement a nicer one by hand.

	utility function to set up an appropriate GValue for us

* generator/SignalHandler.cs : fix some broken/redundant generation in
	the Object/Struct wrapping for sig params.
	* glib/Object.cs : internalize/protect lots of API that shouldn't need
	to be used by non-subclass/non-glib code. Return GType.Object as GType.
	* glib/Value.cs : use internal GLib.Object.NativeType prop.
	* sample/TestDnd.cs : use ToString instead of TypeName.
