This PR changes the way in which the SSL analyzer tracks the direction of connections. So far, the SSL analyzer assumed that the originator of a connection would send the client hello (and other associated client-side events), and that the responder would be the SSL servers. In some circumstances this is not true, and the initiator of a connection is the server, with the responder being the client. So far this confused some of the internal statekeeping logic and could lead to mis-parsing of extensions. This reversal of roles can happen in DTLS, if a connection uses STUN - and potentially in some StartTLS protocols. This PR tracks the direction of a TLS connection using the hello request, client hello and server hello handshake messages. Furthermore, it changes the SSL events from providing is_orig to providing is_client, where is_client is true for the client_side of a connection. Since the argument positioning in the event has not changed, old scripts will continue to work seamlessly - the new semantics are what everyone writing SSL scripts will have expected in any case. There is a new event that is raised when a connection is flipped. A weird is raised if a flip happens repeatedly. Addresses GH-2198.
