r1019: Push the auth subsystem away from using typedef, and over to the 'all
goodness and light' struct ;-)

Break apart the auth subsystem's return strucutres, into the parts
that a netlogon call cares about, and the parts that are for a local
session.  This is the 'struct session_info' and it will almost
completly replace the current information stored on a vuid, but be
generic to all login methods (RPC over TCP, for example).
