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.
The default IME window has to be created for each top-level window in specific condition. It is needed for implementing Japanese input.
- Add IntFocusSetInputContext helper function.
- Call IntFocusSetInputContext after sending WM_KILLFOCUS message.
- Add IntWantImeWindow, co_IntCreateDefaultImeWindow, and IntDestroyOwnedWindows helper functions.
- Create the default IME window (spwndDefaultIme) for the specified window at IntCreateWindow.
- Fix Imm32InternalLockIMC function.

Initialization of device mode list will be done later, just before switching to graphics mode.
If no graphic display is available, we will now fail when starting first GUI application in
co_IntGraphicsCheck(). Add a bugcheck here to prevent frozen screen.
This function can create a MDEV for the whole display (maybe containing multiple
PDEVs), or update settings of a specific PDEV.
- call PDEVOBJ_lChangeDisplaySettings when switching to graphics mode.
- modify EngpGetPDEV to search requested PDEV only in current MDEV
This will be used (later) to store the list of all enabled display devices.
Add a global variable gpmdev (should really be stored in DISPLAYINFO structure)
Replace global variable gppdevPrimary by pmdev->ppdevGlobal.
- make it return a new allocated PDEVMODEW instead of a pointer into
existing PGRAPHICS_DEVICE (usefull when available display modes can
dynamically change: VirtualBox, RDP, ...)
- update all callers

This was introduced historically in commit 583de66b3 (r7460) to
workaround some compiler problems (or replace already existing
GCC-specific __attribute__((packed)) annotations); however these
structures are in-memory-only, do not describe any on-disk data
format and don't describe hardware-specific data. So they should
have the "natural" alignment of the target platform.
They also have to match the documented layouts at:
https://reactos.org/wiki/Techwiki:Win32k/THREADINFOhttps://www.geoffchappell.com/studies/windows/km/win32k/structs/threadinfo/index.htm
at least for the compatible parts that ReactOS shares.
- Add DesktopPtrToUser helper function.
- Fix imm32.ValidateHandleNoErr function.
- Use DesktopHeapAlloc to allocate the IMC, instead of ExAllocatePoolWithTag.
- Use DesktopHeapFree to free the IMC, instead of ExFreePoolWithTag.

It popped up very reliably when performing git-clone of the ros sources
while having the taskmgr open in the processes-tab.
Or when building 'ninja bootcd -j1' while having the taskmgr open in the processes-tab.
It is always possible to ignore it and then continue using ros for days without
noticing any side effects.
James Tabor judged the assert to have a "questionable logic".
Giannis who once added it, was also ok with commenting it.
His words:
This assertion isn't something fatal,
the worst thing that can happen from continuing on it would be
to make the thread get awake more times than it should.

This prevents the tracking menu from erroneously closing itself right after it was opened in some cases.
Fixes CORE-17338 which got unhidden by 0.4.15-dev-1126-g 58b0558f94
And fixes CORE-15760 which got unhidden by SVN r74972 == git 19dd22d422
Since both symptoms look very similar but the unhiding revisions did differ,
that could mean we do have some kind of race condition here.
I guess this fix is more like a workaround. I do intend to port it back nevertheless.
This is an addendum to

We have not seen this happening in real-life yet, but some code-fragments within co_IntSetScrollInfo()
e.g. line 628 if (nBar == SB_CTL) do clearly indicate that nBar can be 2 (SB_CTL).
Some lines below we definitely must not access those 4 static arrays out of bounds then via nBar as access index!
Ftr with a bit of grepping I also found some calls like NtUserSetScrollInfo(Wnd, SB_CTL, &Info, FALSE);
e.g: in win32ss/user/user32/controls/scrollbar.c so I am pretty sure nBar == 2 can happen in practice within co_IntSetScrollInfo().
I question whether any of those reads/writes to those static arrays (or the comparisons) would make any sense on index 2,
so we should aim to eliminate them altogether in the future.

- Do the kernel/server --> user/client-space pointers conversion within
NtUserProcessConnect(), instead of having the callers of this function
doing this job.
This makes the behaviour Windows-compatible.
NOTE: the gHandleEntries pointer is ReactOS-specific!
- Drop the g_ulSharedDelta global, just use instead gSharedInfo.ulSharedDelta.
- Add extra documentation aspects for NtUserProcessConnect() that are
not yet implemented in ReactOS.
DLGWINDOWEXTRA is 30 (both on win32 and win64). This has storage for the following entries: DWLP_MSGRESULT (0), DWLP_DLGPROC (8), DWLP_USER (16)
We used to store the dialog info pointer using SetWindowLongPtr (DWLP_ROS_DIALOGINFO == DWLP_USER+sizeof(ULONG_PTR) == 24), which was fine on win32, but failed on win64, since there wasn't enough space left (24 + 8 = 32 > 30).
Rewrite the way the DLGINFO pointer is stored, by adding an additional field to the WND structure and set it using NtUserxSetDialogPointer (which is what it is for).
Also fix too small cbWndExtra for the button class.

This avoids disclosing pool contents to user mode when not all members
of the respective structure are initialized or when there is padding.
In co_IntCallWindowProc, also zero the stack buffer since this can
be passed to user mode as well, and contains padding.
It popped up 2-3 times for me during several
months of ros usage and I could continue without
noticing any side effects.

- Rename CLIENTTHREADINFO::tickLastMsgChecked into timeLastRead as
documented in https://reactos.org/wiki/Techwiki:Win32k/CLIENTTHREADINFO .
This is the last time the message queue was read.
- This is the structure member one must compare against the current tick
count timestamp in order to heuristically determine whether a message
queue thread is hung!! Fix MsqIsHung() in accordance, add extra debug
logging in order to help us determining which of our code present
regular GUI hangs, and add as well an extra "TimeOut" parameter so as
not to hardcode a fixed value within that function but instead
allowing its caller to specify possible different values.
- THREADINFO::timeLast is on the contrary the last message time stamp,
and will definitively differ from CLIENTTHREADINFO::timeLastRead .
It should only be used for information purposes!
- Accordingly, in NtUserGetThreadState()::THREADSTATE_UPTIMELASTREAD
and in InitThreadCallback(), only (re-)initialize the timeLastRead
member of the CLIENTTHREADINFO structure of the THREADINFO of interest.
- In co_IntPeekMessage(), update more often the timeLastRead timestamp
whenever the current message queue has been read (but NOT timeLast!!
That one will be updated ONLY WHEN a message is found!).
- In co_IntSendMessageTimeoutSingle() first check whether the window to
which we send the message is being destroyed, before checking for
queue hangs etc. Collapse the logic checks for queue hang and increase
the hang timeout check to 4 times MSQ_HUNG (== 4 * 5 seconds) and
display a debug trace.
This is done by creating the volatile key
\Registry\Machine\System\CurrentControlSet\Control\GraphicsDrivers\BaseVideo .
Also cache during first initialization of VIDEOPRT the state of the boot
options BASEVIDEO and NOVESA, so that they can be readily retrieved later
(for example, in VideoPortIsNoVesa()).
CORE-12149
VIDEOPRT:
=========
Improve interfacing with INBV, so as to detect when an external module
acquired INBV display ownership, and whether ownership is being released
later on. (This does NOT rely on hooking!)
For this purpose we improve the IntVideoPortResetDisplayParameters(Ex)
callback that gets registered with an InbvNotifyDisplayOwnershipLost()
call during initialization, and we add a monitoring thread.
The callback is called whenever an external module calls
InbvAcquireDisplayOwnership(), for example the bugcheck code or the KDBG
debugger in SCREEN mode. When this happens, a flag that tells the
monitoring thread to start monitoring INBV is set (ReactOS-specific),
and the display adapters get reset with HwResetHw() (as done on Windows).
Due to the fact that this INBV callback can be called at *ANY* IRQL, we
cannot use dispatcher synchronization mechanisms such as events to tell
the INBV monitoring thread to start its operations, so we need to rely
instead on a flag to be set. And, since INBV doesn't provide with any
proper callback/notification system either, we need to actively monitor
its state by pooling. To reduce the load on the system the monitoring
thread performs 1-second waits between each check for the flag set by
the INBV callback, and during checking the INBV ownership status.
When the INBV ownership is detected to be released by an external module,
the INBV callback is re-registered (this is *MANDATORY* since the
external module has called InbvNotifyDisplayOwnershipLost() with a
different callback parameter!), and then we callout to Win32k for
re-enabling the display.
This has the virtue of correctly resetting the display once the KDBG
debugger in SCREEN mode is being exited, and fixes CORE-12149 .
The following additional fixes were needed:
VIDEOPRT & WIN32K:
==================
Remove the registration with INBV that was previously done in a ReactOS-
specific hacked IRP_MJ_WRITE call; it is now done correctly during the
video device opening done by EngpRegisterGraphicsDevice() in the VIDEOPRT's
IRP_MJ_CREATE handler, as done on Windows.
WIN32K:
=======
- Stub the VideoPortCallout() support, for VIDEOPRT -> WIN32 callbacks.
This function gets registered with VIDEOPRT through an
IOCTL_VIDEO_INIT_WIN32K_CALLBACKS call in EngpRegisterGraphicsDevice().
- Only partially implement the 'VideoFindAdapterCallout' case, that just
re-enables the primary display by refreshing it (using the new function
UserRefreshDisplay()).
VIDEOPRT:
=========
- PVIDEO_WIN32K_CALLOUT is an NTAPI (stdcall) callback.
- In the IntVideoPortResetDisplayParameters(Ex) callback, reset all the
"resettable" adapters registered in the HwResetAdaptersList list.
We thus get rid of the global ResetDisplayParametersDeviceExtension.
- Make the IntVideoPortResetDisplayParameters(Ex) callback slightly more
robust (using SEH) against potential HwResetListEntry list corruption
or invalid DriverExtension->InitializationData.HwResetHw() that would
otherwise trigger a BSOD, and this would be disastrous since that
callback is precisely called when INBV is acquired, typically when the
BSOD code initializes the display for displaying its information...
Extras:
- Validate the IrpStack->MajorFunction in IntVideoPortDispatchDeviceControl()
and implement IRP_MJ_SHUTDOWN handling. Stub out the other IOCTLs that
are handled by VIDEOPRT only (and not by the miniports).
- VIDEOPRT doesn't require IRP_MJ_INTERNAL_DEVICE_CONTROL (unused).
- Implement IOCTL_VIDEO_PREPARE_FOR_EARECOVERY that just resets the
display to standard VGA 80x25 text mode.
