r6464: Remove the last of the Samba3 NTLMSSP API. This removes the rudundent
struct ntlmssp_state, and pushes all the member elements into struct gensec_ntlmssp_state. This also removes the 2-layer start function, caused by the previous double abstraction layer. Andrew Bartlett (This used to be commit eebbb4205b335214d24974f3be825846f6227f0c)
