Improve IPv6 support, enabling IPv6 traffic on (almost) all dissectors. (#1380)
There are no valid reasons for a (generic) protocol to ignore IPv6
traffic.
Note that:
* I have not found the specifications of "CheckPoint High Availability
Protocol", so I don't know how/if it supports IPv6
* all LRU caches are still IPv4 only
Even if src_id/dst_id stuff is probably useless (see #1279), the right
way to update the protocol classification is via `ndpi_set_detected_protocol()`
