    Fix some warnings that creep up when compiling without INVARIANTS.
    
    * Add a __debugvar define to <sys/systm.h> which is empty when INVARIANTS
      is set (default) and __attribute__((unused)) when INVARIANTS is not set.
    
    * Use __debugvar in the declaration of variables which are only used in a
      KASSERT or KKASSERT to avoid 'unused variable' warnings.
