This replaces the existing MBOX update code with a more generalized calculation for emitting mbox updates. We also create a sentinel for doing the updates so we can more abstractly deal with the rings. When doing MBOX updates the code must be aware of the /other/ rings. Until now the platforms which supported semaphores had a fixed number of rings and so it made sense for the code to be very specialized (hardcoded). The patch does contain a functional change, but should have no behavioral changes.
