Note to SELF and EVERYONE: the commit implements the initial logon session termination notification implementation, the SeMarkLogonSessionF

[NTOS:SE] Implement logon session termination notification

Note to SELF and EVERYONE: the commit implements the initial logon session termination notification implementation, the SeMarkLogonSessionForTerminationNotification function, but as it currently stands there are several other tasks to be addressed in the future in order for the logon termination notification to be fully completed. The tasks as of which are.

1. Our SepRmDereferenceLogonSession is not fully implemented, as it doesn't inform the LSA and filesystems of logon deletion notification
2. Implement two worker routines that are actually in charge of such tasks of informing LSA and FSDs
3. Perform logon deletion
4. Do further investigations and check whatever that is left to address, if any

[FORMATTING][NTOS][HAL][DRIVERS][SDK] Fix trailing spaces

[NTOS:SE] Implement logon session deletion

And declare a prototype for SepCleanupLUIDDeviceMapDirectory and annotate it with SAL.

[NDK][NTOS:SE] Add the missing "LogonSession" member to TOKEN structure

And also fix the wrong member offsets in comments. The said offset values are based upon the ones retrieved with WinDBG.

[NTOS:SE] Annotate the function parameters of SepRegQueryHelper with SAL

And add a documentation comment header

[NTOSKRNL] Implement SeRegisterLogonSessionTerminatedRoutine() and SeUnregisterLogonSessionTerminatedRoutine().

[NTOSKRNL] Taggify some allocs

[NTOSKRNL] Implement SepCleanupLUIDDeviceMapDirectory
This will clean up all the links (drive letters) created
by an user on session deletion once LUID device maps are
in use

[NTOSKRNL] On session last reference removal, dereference LUID device map

[NTOSKRNL] Implement SeGetLogonIdDeviceMap

[NTOSKRNL] Stub SeGetLogonIdDeviceMap

Git conversion: Make reactos the root directory, move rosapps, rostests, wallpapers into modules, and delete rossubsys.
