  1. sd-bus: deal with cookie overruns 

    Apparently this happens IRL. Let's carefully deal with issues like this:
when we overrun, let's not go back to zero but instead leave the highest
cookie bit set. We use that as indication that we are in "overrun
territory", and then are particularly careful with checking cookies,
i.e. that they haven't been used for still outstanding replies yet. This
should retain the quick cookie generation behaviour we used to have, but
permits dealing with overruns.
