pinger: Fix buffer overflow in Icmp6::Recv

Do not blindly forward cache peer CONNECT responses.

Squid blindly forwards cache peer CONNECT responses to clients. This
may break things if the peer responds with something like HTTP 403
(Forbidden) and keeps the connection with Squid open:
  - The client application issues a CONNECT request.
  - Squid forwards this request to a cache peer.
  - Cache peer correctly responds back with a "403 Forbidden".
  - Squid does not parse cache peer response and
     just forwards it as if it was a Squid response to the client.
  - The TCP connections are not closed.

At this stage, Squid is unaware that the CONNECT request has failed. All
subsequent requests on the user agent TCP connection are treated as
tunnelled traffic. Squid is forwarding these requests to the peer on the
TCP connection previously used for the 403-ed CONNECT request, without
proper processing. The additional headers which should have been applied
by Squid to these requests are not applied, and the requests are being
forwarded to the cache peer even though the Squid configuration may
state that these requests must go directly to the origin server.

This fixes Squid to parse cache peer responses, and if an error response
found, respond with "502 Bad Gateway" to the client and close the
connections.

Fix various ICMP handling issues in Squid pinger

* ICMP code type logging display could over-read the registered type
  string arrays.

* Malformed ICMP packets were accepted into processing with undefined
  and potentially nasty results.

Both sets of flaws can result in pinger segmentation fault and halting
the Squid functionality relying on pinger for correct operation.

 Thanks to the OpenSUSE project for analysis and resolution of these.
