Log:
[KSECDD]
- Fix a typo in KsecQueryFileInformation
- Implement missing ioctls in KsecDeviceControl
- Support METHOD_OUT_DIRECT for IRP_MJ_DEVICE_CONTROL
- Add stubs for KsecEn/DecryptMemory
[ADVAPI32]
- Use ksecdd to handle SystemFunction040 (RtlEncryptMemory) and SystemFunction041
(RtlDecryptMemory) (they still do nothing, but at least they do it in kenrnel mode now
;-))
