[linux-smb2-client][PATCH] Make ntlmv2 as auth mech within NTLMSSP

[shirishpargaonkar at gmail.com]

Make ntlmv2 as an authentication mechanism within ntlmssp
instead of ntlmv1.

Parse type 2 response in ntlmssp negotiation to pluck
AV pairs and use them to calculate ntlmv2 response token.
Also, assign domain name from the sever response in type 2
packet of ntlmssp and use that (netbios) domain name in
calculation of response.
