* #if, #ifdef, #ifndef, #else, #elif and #endif state management
*
* #if state transitions are made on basis of the current TOS and the next
* required state. The state transitions are required to housekeep because
* #if:s can be nested. The ignore case is activated to prevent output from
* within a false clause.
* Some special cases come from the fact that the #elif cases are not
* binary, but three-state. The problem is that all other elif-cases must
* be false when one true one has been found. A second problem is that the
* #else clause is a final clause. No extra #else:s may follow.
*
* The states mean:
* if_true Process input to output
* if_false Process input but no output
* if_ignore Process input but no output
* if_elif Process input but no output
* if_elsefalse Process input but no output
* if_elsettrue Process input to output
*
* The possible state-sequences are [state(stack depth)] (rest can be deduced):
* TOS #if 1 #else #endif
* if_true(n) if_true(n+1) if_elsefalse(n+1)
* if_false(n) if_ignore(n+1) if_ignore(n+1)
* if_elsetrue(n) if_true(n+1) if_elsefalse(n+1)
* if_elsefalse(n) if_ignore(n+1) if_ignore(n+1)
* if_elif(n) if_ignore(n+1) if_ignore(n+1)
* if_ignore(n) if_ignore(n+1) if_ignore(n+1)
