Add some more tests to the ntlm_auth diagnositics package.

Our NTLMv2 client code needs work, becouse we don't get the session key for
any of the NTLMv2 stuff...

Also test some of the more 'odd' auth cases - like putting the NT password
into the LM feild.

Clean up some static globals into static locals.
