- AYIYA works.
- AYIYA analyzed connections are still labelled wrong in conn.log (logged as syslog)
- Some clean up for left over code.
- Small refactoring to pass packets back from analyzers to core.
- $uid is now optional in conn logs since ip-in-ip tunnel parent's
won't have an actual connection.
UDP tunnel support removed for now, to be re-added in specific
analyzers later, but IP-in-IP is now decapsulated recursively
so nested tunnels can be seen and the inner packets get sent
through the IP fragment reassembler if necessary.

Just trying to bring topic/gregor/tunnel up to date in this new branch.
Compiles, but untested.
- The 'icmp_conn' record now contains an 'hlim' field since hop limit
in the IP header is an interesting field for at least these ND
messages.
- Changed 'icmp_router_advertisement' event parameters.
'router_lifetime' is now an interval. Fix 'reachable_time' and
'retrans_timer' using wrong internal Val type for intervals.
Made more of the known router advertisement flags available through
boolean parameters.
- Changed 'icmp_neighbor_advertisement' event parameters to add
more of the known boolean flags.
* origin/topic/icmp6:
Fixes for IPv6 truncation and ICMP/ICMP6 analysis.
Change ICMPv6 checksum calculation to use IP_Hdr wrapper.
Update IPv6 atomic fragment unit test to filter output of ICMPv6.
Add more data to icmp events
More code cleanup
Add more icmpv6 events, and general code cleanup
Fix compile failure after merge from master
Significant edit pass over ICMPv6 code.
Porting Matti's branch to git.
Closes#808.
This should it make easier for other people to understand what is going on without having knowledge of an "internal api * means * in external api" mapping.
- Add more guards against trying to analyze captured packets with a
truncated IPv6 static header or extension header chain.
- Add back in the ICMP payload tracking for ICMP "connections".
- Fix 'icmp_context' record construction. Some field assignments
were mismatched for ICMP and ICMP6. Source and destination
addresses were set incorrectly for context packets that don't
contain a full IP header. Some fields for ICMP6 weren't filled out.
- Changed ICMP Time Exceeded packets to raise the 'icmp_time_exceeded'
event instead of 'icmp_error_message'.
- Add unit tests for truncation and the main types of ICMP/ICMP6
that have specific events.
- Documentation clarifications.
