    [SK_BUFF]: Introduce skb_reset_transport_header(skb)
    
    For the common, open coded 'skb->h.raw = skb->data' operation, so that we 
can
    later turn skb->h.raw into a offset, reducing the size of struct sk_buff in
    64bit land while possibly keeping it as a pointer on 32bit.
    
    This one touches just the most simple cases:
    
    skb->h.raw = skb->data;
    skb->h.raw = {skb_push|[__]skb_pull}()
    
    The next ones will handle the slightly more "complex" cases.
