NtQueryInformationToken is by far the only system call in NT where ReturnLength simply cannot be optional. On Windows this parameter is always probed and an argument to NULL directly leads to an access violation exception.
This is due to the fact of how tokens work, as its information contents (token user, owner, primary group, et al) are dynamic and can vary throughout over time in memory.
What happens on current ReactOS master however is that ReturnLength is only probed if the parameter is not NULL. On a NULL case scenario the probing checks succeed and NtQueryInformationToken fails later. For this, just get rid of CompleteProbing
parameter and opt in for a bit mask flag based approach, with ICIF_FORCE_RETURN_LENGTH_PROBE being set on DefaultQueryInfoBufferCheck which NtQueryInformationToken calls it to do sanity checks.
In addition to that...
- Document the ICIF probe helpers
- Annotate the ICIF prope helpers with SAL
- With the riddance of CompleteProbing and adoption of flags based approach, add ICIF_PROBE_READ_WRITE and ICIF_PROBE_READ flags alongside with ICIF_FORCE_RETURN_LENGTH_PROBE
MFC42 applications only expect an IME window when on a DBCS system,
so they will capture this IME window as their 'main' window on non-DBCS systems.

- Fix the LANGUAGE declaration in de-DE.rc (originally was copy-pasted
from en-US, and thus caused the build break).
- Include de-DE.rc in alphabetical order in diskpart.rc
Implement the following DxEng* functions:
- DxEngAltLockSurface
- DxEngDeleteSurface
- DxEngReferenceHdev
- DxEngSelectBitmap
- DxEngSetBitmapOwner
- DxEngUnreferenceHdev
Update their prototypes and call the appropriate win32k functions
inside them, since they are already implemented. Also get rid of
now unused IntGdi(Un)ReferencePdev, whose were called only by dxeng,
and whose are not used anymore. In Windows, DxEng(Un)ReferenceHdev calls
PDEVOBJ_vReferencePDEV and PDEVOBJ_vDeferencePDEV directly (those
correspond to our PDEVOBJ_vReference and PDEVOBJ_vRelease accordingly).
Required by MS DirectDraw stack (ddraw.dll & dxg.sys). CORE-17561
- [VIDEOPRT] Return the real PhysicalDeviceObject in Win32k callbacks.
- [WIN32SS:ENG] Pass PhysDeviceObject into the GraphicsDevice structure
and rename the destination field accordingly.
- [WIN32SS:NTUSER] Request hardware identifiers from device PDO and
fill DISPLAY_DEVICE's DeviceID field with the first identifier.
Now it's correctly passed to the usermode, and Desktop Propertes applet
can open the video adapter device properties.
Thanks to Hervé Poussineau for the help.

The current state of Security manager's code is kind of a mess. Mainly, there's code scattered around places where they shouldn't belong and token implementation (token.c) is already of a bloat in itself as it is. The file has over 6k lines and it's subject to grow exponentially with improvements, features, whatever that is.
With that being said, the token implementation code in the kernel will be split accordingly and rest of the code moved to appropriate places. The new layout will look as follows (excluding the already existing files):
- client.c (Client security implementation code)
- objtype.c (Object type list implementation code -- more code related to object types will be put here when I'm going to implement object type access checks in the future)
- subject.c (Subject security context support)
The token implementation in the kernel will be split in 4 distinct files as shown:
- token.c (Base token support routines)
- tokenlif.c (Life management of a token object -- that is Duplication, Creation and Filtering)
- tokencls.c (Token Query/Set Information Classes support)
- tokenadj.c (Token privileges/groups adjusting support)
In addition to that, tidy up the internal header and reorganize it as well.
Fix MiInsertSharedUserPageVad to not charge the system process pool quota.
Even though PsChargeProcessNonPagedPoolQuota itself checks if the process specified is the system process, this doesn't work here as we're too early into boot for the kernel to know what the system process is.
