        * ghook.[hc]: destruction cleanup. there's one
        ->finalize_hook member in the hooklist now that gets
        called when a hook should be destroyed, that's it.
        that function is guarranteed to be called only when
        all ref_counts to the hook vanished, thus also when
        the hook is not in call.

        * gparamspecs.[hc]: s/g_param_spec_string_c/g_param_spec_stringc/.

        * gsignal.[hc]: fixed accumulator invocation, implemented emission
        hooks. and no, neither of these callbacks are called via a closure,
        language bindings can wrap the accumulator and emission hook
        interface, they already get parameters marshalled into a GValue array.
        (g_signal_connect): removed this function as its C specific, doesn't
        cover the swapped argument, is too close to its broken original
        gtk_signal_connect() and creates demand for _swapped, _after and
        _swapped_after variants <brrr>.
        (g_signal_connectc): convenience macro to connect a C handler
        func with data, like the old g_signal_connect() plus swapped
        argument.

        * gtype.h:
        * gboxed.c: added G_TYPE_VALUE boxed type.
