NTLM authentication and signing - Calculate auth response per smb session
Start calculation auth response within a session. Move/Add pertinet
data structures like session key, server challenge and ntlmv2_hash in
a session structure. We should do the calculations within a session
before copying session key and response over to server data
structures because a session setup can fail.
Only after a very first smb session succeeds, it copies/makes its
session key, session key of smb connection. This key stays with
the smb connection throughout its life.
