Now that RID_MAX has reached 255, we need to update the bit sizes of every

Sorry to bring this up so late, but this does raise the question of 
whether we actually want to use keyword space for all these traits that 
will probably be used approximately once in a C++ translation unit.  I 
wonder if it would make sense to instead use e.g. RID_TRAIT for all of 
them and use gperf to look up the specific trait from the identifier?
