Fix alarm delivery-order sorting

We also refine the order of delivery within any given package.  Now,
we identify which apps have wakeup alarms being delivered in the
current pass, and deliver all of that app's alarms before moving
on to alarm delivery to apps who are only receiving non-wakeup alarms
in the current delivery pass.  The TIME_TICK alarm is also hoisted to
the start of the current delivery pass if present.
