Fix code that would trip -Wtype-limits
This patch fixes up all code that would throw a -Wtype-limits warning. This sometimes involves eliminating unnecessary checks, adding a few odd but harmless casts or just pragma'ing out the warning for a whole file -- I tried to find the path of least resistance. I think the overall benefit of the warning outweighs the occasional weirdness.
