r4635: Fix NTLMSSP to return NT_STATUS_OK when it has constructed the auth
token in the client (the final token in the negotiation). Consequential fixes in the SPNEGO code, which now uses the out.length as the indicator of 'I need to send something to the other side'. Merge the NTLM and SPNEGO DCE-RPC authentication routines in the client. Fix the RPC-MULTIBIND test consequent to this merge. Andrew Bartlett (This used to be commit 43e3516fc03008e97ebb4ad1a0cde464303f43c6)
