r11789: - add the start of a SMB2 server
- it does Negprot and SessionSetup yet the rest returns NT_STATUS_NOT_IMPLEMENTED - it's off by default, enable with: smbsrv:enable smb2 = yes - negotition in the SMB Negprot isn't supported yet - it's only tested with smbtorture SMB2-CONNECT not with vista as client metze (This used to be commit 08b31d5f618d2e416cb9812ad3a49754cd7212b8)
