Jon Siwek 49b8c7e390 Add analyzer for GSI mechanism of GSSAPI FTP AUTH method.
GSI authentication involves an encoded TLS/SSL handshake over the FTP
control session.  Decoding the exchanged tokens and passing them to an
SSL analyzer instance allows use of all the familiar script-layer events
in inspecting the handshake (e.g. client/server certificats are
available).  For FTP sessions that attempt GSI authentication, the
service field of the connection record will have both "ftp" and "ssl".

One additional change is an FTP server's acceptance of an AUTH request
no longer causes analysis of the connection to cease (because further
analysis likely wasn't possible).  This decision can be made more
dynamically at the script-layer (plus there's now the fact that further
analysis can be done at least on the GSSAPI AUTH method).
