A few changes:

drop paramaters:
 status
 utmp hostname

change session code to always record each vuid current on the server.  The sessionid struct is no longer packed, as I couldn't get that to work ;-)

change smbstatus to show this info and less of the connections.tdb info (its not actualy that accurate).

I'll get swat doing some of this shortly.
(This used to be commit b068ad300527c44673bbee0aede7849199c89de7)
