First, make absolute times unsigned. This means that it's safe to depend on their overflow behaviour (which is undefined for signed integers). This requires a little extra care in handling comparisons, but I think I've correctly adjusted them all. Second, functions registered with schedule_timer() are guaranteed to be called with precisely the time that was returned by schedule_timer(). Thus, it's only necessary to check these values for equality rather than doing risky range checks, so do that. The timing code still does lots that's undefined, unnecessary, or just wrong, but this is a good start. [originally from svn r9667]
