Also fix header truncation check for IPv6 No Next header and add an
"ipv6_no_next" weird for such packets that aren't tunneled over Teredo
(which it calls "bubbles" and are used to create mappings in NATs).
conn.log now sets a field indicating all the parent tunnel UIDs over
which a connection operated and cross reference the UIDs found in
the tunnel.log.
Also some renaming of tunnel related types at the scripting layer.
- 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.
