Use more standard section names in an attempt to unconfuse new users (and make it easier to find stuff for the old ones).  I originally put everything under one "RULE SUBSYSTEM" so it didn't look like devfs(8) is dedicated to the rule subsystem, but since nobody has any idea what else might go here, it's not worth confusing people just to save a little time for someone that might add something rule-unrelated to devfs(8) in a few years.
