Load the DirectX graphics kernel driver (dxg.sys) by win32k at WINSRV
initialization time, in NtUserInitialize(). Keep it always loaded in
memory, as on Windows, instead of loading it only by DirectX dlls.
This fixes the problem of acessing this driver: we need only to call
DxDdEnableDirectDraw() and do other stuff when DirectDraw/Direct3D is
required by anything. In other cases, it is called from win32k PDEV
functions when changing display mode (as in Windows). Since it's used
by other things too, it needs to be always loaded.
Otherwise, if it's not loaded, its APIs are not accessible when needed,
and execution fails.
For example, it fixes display mode change problem in VMWare, when a
new mode fails to be applied. Indeed, when it manages DirectDraw stuff,
it calls DXG routines, and therefore fails if dxg.sys isn't loaded
in memory at this moment.
- Implement InitializeGreCSRSS() initialization routine, that initializes
supplemental NTGDI/GRE data once CSRSS and WINSRV are loaded:
* Call DxDdStartupDxGraphics() inside it, which loads dxg.sys.
* Additionally, move fonts and language ID initialization there, from
win32k!DriverEntry. Confirmed by analysis on Windows.
- Call InitializeGreCSRSS() in NtUserInitialize() main initialization routine
(called by WINSRV initialization).
Moved to NTGDI from previously NTUSER place:

Fixes symptom "mouse pointer vanishes when closing
applications via x in title-bar"
The bug in WIN32SS was unhidden by SVN r65496 == git
5c1a8109c8
, when we introduced explorer_new. The old explorer
had a workaround built within.
Many thanks to patches author James Tabor.
I intend to backport into 0.4.13RC as well.

- 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.
* Add an NDK header to define INIT_FUNCTION/INIT_SECTION globally
* Use _declspec(allocate(x)) and _declspec(code_seg(x)) on MSVC versions that support it
* Use INIT_FUNCTION on functions only and INIT_SECTION on data only (required by MSVC)
* Place INIT_FUNCTION before the return type (required by MSVC)
* Make sure declarations and implementations share the same modifiers (required by MSVC)
* Add a global linker option to suppress warnings about defined but unused INIT section
* Merge INIT section into .text in freeldr
- NtUserSetInformationThread: Stub UserThreadUseActiveDesktop and UserThreadRestoreDesktop
- Properly mark the first thread that enters win32k belonging to csrss. At this point we assume that since gpepCSRSS isn't initialized yet, it probably is the first thread.
[WINSRV] Use NtUserSetInformationThread to set the current desktop when needed
-When csrss needs to use user32 or enter win32k, it first needs to assign the current thread to a desktop.
Normally CSRSS must not be connected to any winsta or desktop by default. It should manually connect
to a winsta/desktop only when it has to do some GUI operations, and then disconnect afterwards.
[USERSRV] Temporarily hackfix the harderror dialog display to the current input desktop.
as documented in "Advanced Windows NT" by Jeffrey M. Richter (Microsoft Press),
and in https://is.muni.cz/el/1433/jaro2010/PB167/um/cv5/undocumented_CreateProcess.pdf .
[INCLUDE][SERVICES][WIN32K:NTUSER] Add an undocumented STARTF_INHERITDESKTOP flag
for the STARTUPINFO::dwFlags structure member, whose purpose is to tell Win32k
that the created handles to the window station and desktop to which the
process is connecting to, can be inherited by its child processes.
It is used when starting interactive services.
Observed via API monitoring on Windows 2003.
CORE-11933 and PR #621.
Since this API is also called from WINSRV when calling the AllocConsole() API,
it can be tested more-or-less easily. The internal helper IntResolveDesktop()
is also tested during process connection to a window station, when such process
first calls a USER32 or GDI32 function.
This is also the functionality tested by the user32:desktop apitest.
- Adjust how IntResolveDesktop() is called.
