Fixed issue in state machine
Some styling tweaks
Implement protocol confirmation
Analyzer and bro script for RFB protocol (VNC)
* <seth> I also applied a bit of clean up to the base
script to make it match other scripts better and
updated tests.
Do not set the service field in the bro script but
use the protocol confirmation paradigm.
Protocol is considered confirmed if both a
succesful client and server banner have been
parsed.
This analyzer parses the Remote Frame Buffer
protocol, usually referred to as the 'VNC protocol'.
It supports several dialects (3.3, 3.7, 3.8) and
also handles the Apple Remote Desktop variant.
It will log such facts as client/server versions,
authentication method used, authentication result,
height, width and name of the shared screen.
It also includes two testcases.
Todo: Apple Remote Desktop seems to have some
bytes prepended to the screen name. This is
not interepreted correctly.
