better name for var_integer et.al.

Ada calls such numbers "Positive". var_positive might be a good name.

I can't see any use for this semantics, but maybe it's due to my limited
experience. I looked at the current code, and most if not all of them
where just misuses of this kind. Some of them are really booleans (so I
suspect var_zinteger would be better), or postive numbers (so
var_positive would be better).

I not useful, I would consider just removing it.

var_integer? (assuming we get rid of the non-zero signed integer)
