        Bug 571169 – make floating references generic

        * gobject/valaccodebasemodule.vala:
        * vala/valainterface.vala:
        * vala/valaclass.vala:
        * vala/valaobjectcreationexpression.vala:
        * vala/valasemanticanalyzer.vala:
        * vala/valatypesymbol.vala:

        Add support for 'ref_sink_function' CCode attribute on classes.
        Use this instead of hardcoding g_object_ref_sink() for
        GInitiallyUnowned.

        * vapi/gobject-2.0.vapi:

        Set ref_sink_function on InitiallyUnowned class.
