Changes to IPv6 ext. header parsing (addresses #795).

Browse source 
In response to feedback from Robin:

  - rename "ip_hdr" to "ip4_hdr"

  - pkt_hdr$ip6 is now of type "ip6_hdr" instead of "ip6_hdr_chain"

  - "ip6_hdr_chain" no longer contains an "ip6_hdr" field, instead
    it's the other way around, "ip6_hdr" contains an "ip6_hdr_chain"

  - other internal refactoring
