syslog GSS-API usage notes

I copy over some usage notes from Peter Vrabec’s intial announcement of the patch:

It adds a new commandline option ‘-g’ to listen for a connection wrapped with gss-api and few new configuration directives:

for server:

$gsslistenservicename <service name>

for client:

$gssforwardservicename <service name>
$gssmode <encryption|integrity|none>

With gssmode set to “encryption” or “integrity” all tcp selectors will be forwarding messages via gss-api.

That’s probably useful while I am getting up some real documentation.
