    ip_forward: fix IPv4 forwarding with multiple netifs/offloading
    
    When we have multiple netifs where at least one has checksum offloading
    capabilities, IP forwarding needs to set various checksum fields to 0
    to prevent HW algorithms on calculating an invalid checksum.
    
    -> set checksum fields of IP/UDP/TCP/ICMP to 0 in ip4_forward().
    
    See bug #56288

    icmp: add a dedicated struct for the standard ICMP header
    
    This is just to keep the code clean and prevent using the "echo" header
    where any ICMP header is meant.
