You're on the right track. The right thing to do is have two variables
on each descriptor:
.callback: Function pointer to a nanny type function
.state: Used like it is now, but instead of representing full
state, a callback can use it to represent a substate so
each subsystem can combine multiple situations into a
single callback.
Compatibility would be easy. By default, you still point callback at
the existing nanny function and use the existing states. Instead of
just changing states though when we used to do that, you'll have to
change callbacks and sometimes states.
This allows situations where STATE(d) is CON_PLAYING but the user is
being prompted for verification of something, for example. You could
even have a 'newbie mode' magic system with an interactive magic
menu, though that'd be kinda dumb. :)
