    ipfilter: Introduce the new FORMAT_IF macro
    
    Interface names stored in the ipstate_t and ipnat_t structures can be
    NULL. This occurs when an application, such as named, is running on the
    firewall machine itself. For example an application, i.e. named, running
    on the firewall itself will cause a state table display and NAT mapping
    display to show a null ingress interface and its egress interface. This
    is perfectly valid but confusing to human eyes. Rather than print
    nothing, print "(null)".
    
    (cherry picked from commit 915395a2800a09a64ae41ca96eabcb5e16b44309)
