Replace "boolean.h" with <stdbool.h>

Be consistent with other programs in base and unify variable usage as
follows to improve readability:

bool = (bool == No) ? Yes : No  ->  bool = !bool
if (bool == Yes)                ->  if (bool)
if (bool == No)                 ->  if (!bool)
bool = Maybe                    ->  bool = -1

OK millert
