Does STRINGNULL actually pass around as NULL? Or is it a pointer to
some magic STRING that just is null?
I ask because splint is very good at tracking when things are
actually NULL, and if we hide NULL behind STRINGNULL, we lose that.
If STRINGNULL is a singleton valid string like PMCNULL is for PMCs, it
would actually be useful for us with this change, because in many places
we can say for sure that a string argument should absolutely never be NULL.
