[WINLOGON]

- Implement the STATE_LOCKED and STATE_LOCKED_SAS states and their transitions.

[MSGINA]
- Disable the logoff button of the security dialog if the AutoAdminLogon option is enabled.
- Implement the unlock computer dialog. The user name and password check is not implemented yet. Just press OK to unlock the computer.
- Simulate an SAS when the DisableCAD option is enabled and the computer is locked. The unlock dialog appears immediately.
