[WIN32K:NTUSER] Implement security infrastructure for NTUSER component Implement a base security infrastructure with code that sets up a security descriptor for the service that we're going to connect through it. Such service is based upon a desktop and a window station. === DOCUMENTATION REMARKS === The authenticated user, represented by an access token that describes its security context, is the main holder and has ultimate power against the default created desktop and window station objects in USER. The authenticated user in question is the actual logged in user, this is the case when the server is impersonating a client. Administrators on the other hand have some share of power against default desktop but their power in question is extremely limited against the default window station as admins can only just enumerate the available and valid handle stations within a desktop.

[WIN32K:NTUSER] Assign a security descriptor when parsing the desktop object The problem ReactOS currently faces is this -- whenever the desktop is being parsed we aren't assigning a security descriptor to it. As a matter of fact when Winlogon tries to assign new security information to the application desktop when a user logs in, Winlogon fails because no prior descriptor has been created for it even though we already do this when initializing security buffers in Winlogon. With that said, we must assign a descriptor when parsing the desktop as well. This fixes a hack in Winlogon where security assigning of application desktop during a log in is disabled (which we can now enable such code path back).
