The struct is used to simplify interpretting and creating values to be
stored in the atomic state variable. I do not think it makes sense that
the atomic variable type itself is part of it.

A compilation check would be nice. Is that possible?

I am renaming the struct to nbcon_state. Also the variable will be
called nbcon_state. With the description updated, I think it makes it
clearer that "struct nbcon_state" is used to interpret/create values of
console->nbcon_state.
