    GListModel: roll back use of type redefinition
    
    We declare the typedefs for GListModel and GListStore in giotypes.h, as
    a matter of convention.  This is not actually required, since the
    typedef is emitted as part of the G_DECLARE_* macros.
    
    The giotypes.h approach is only used to avoid cyclic dependencies
    between headers, which is not a problem in this case.
    
    Type redefinition is a C11 feature, and although it was around in some
    compilers before then, gcc 4.2.1 (from 2007) is apparently still in wide
    use, being the default compiler for OpenBSD.
    
    Eventually, we will probably hit a case where we actually need to
    redefine a type, but since we're not there yet, let's back off a bit.
