Frank Honza 1c8943dedd add RFB parser 
This commit adds support for the Remote Framebuffer Protocol (RFB) as
used, for example, by various VNC implementations. It targets the
official versions 3.3, 3.7 and 3.8 of the protocol and provides logging
for the RFB handshake communication for now. Logged events include
endpoint versions, details of the security (i.e. authentication)
exchange as well as metadata about the image transfer parameters.
Detection is enabled using keywords for:

 - rfb.name: Session name as sticky buffer
 - rfb.sectype: Security type, e.g. VNC-style challenge-response
 - rfb.secresult: Result of the security exchange, e.g. OK, FAIL, ...

The latter could be used, for example, to detect brute-force attempts
on open VNC servers, while the name could be used to map unwanted VNC
sessions to the desktop owners or machines.

We also ship example EVE-JSON output and keyword docs as part of the
Sphinx source for Suricata's RTD documentation.

Jason Ish 4111272c88 config/anomaly: use enabled key word; cleanups 
The anomaly section was commented out, but the types sub object
was not, which then attached the types keyword to the previous
object.

Instead keep "anomaly" enabled in the yaml (not commented out)
and use the "enabled: no" to have it disabled by default.

Additonally reformat the comments to be better viewed in 80
columns.

yet.

Implement as Suricata tunnel similar to Teredo.

Phil Young 05271bfbe5 napatech: simplify integration with Napatech cards 
- There is now an option to automatically create streams on the
  correct NUMA node when using cpu affinity.

- When not using cpu affinity the user can specify streams to be
  created in the suricata.yaml file.  It is no longer required to
  use NTPL to create streams before running suricata.

- The legacy usage model of running NTPL to create streams is still
  available. This can be used for legacy configurations and complex
  configurations that cannot be satisfied by the auto-config option.
