        * gsignal.[hc]: publically define GSignalInvocationHint structure
        that gets passed in to closure invocations. added signal details.
        renamed GSignalType to GSignalFlags to comply with conventions.
        quite some cleanups and minor fixes. avoid uneccessary handler list
        walks upon invokation of after handlers. relookup handler list for
        restarted emissions. preliminary abort normal handler invokation if
        after handler is encountered.

        * glib-genmarshal.c:
        * gclosure.[hc]: moved invocation_hint to the end of the
        g_closure_invoke() arguments as sugegsted by kenelson.
        also made it a gpointer to be more generic. the invocation_hint
        is a caller specific thing that can be used to pass additional
        data in to closure invocations as documented with the caller
        invoking the closure.
