[USER32] GetQueueStatus() should not return 0 when passing QS_ALLINPUT flag that includes QS_RAWINPUT (#4115)
GTK applications call GetQueueStatus(QS_ALLINPUT), where QS_ALLINPUT
specifies the QS_RAWINPUT flag as well, when these are compiled for
Windows XP+, and they expect the call to succeed on this platform.
On one side, ReactOS does not currently support this flag at all, but
since it claims to be XP/2003-compatible, applications may implicitly
expect the flag to be supported by GetQueueStatus() and the function
*NOT* failing when this flag is set.
(Later GTK apps don't care and just call GetQueueStatus(QS_ALLINPUT)
that includes QS_RAWINPUT, and therefore would fail as well on e.g.
Windows 2000...)
Otherwise, an observable effect is that some versions of libgdk-win32-2.0.0.dll
enter into an infinite loop when calling GetQueueStatus(QS_ALLINPUT),
since this call always failed on ReactOS.
On the other side, however, we should honour our winetests that handle
the presence of the QS_RAWINPUT flag and behave differently accordingly.
But since we do not support QS_RAWINPUT yet, we should keep their old
behaviour where QS_RAWINPUT is unused.
Thus, in order to accomodate both sides, we don't fail the GetQueueStatus()
call, but just set the ERROR_INVALID_FLAGS last error and continue it.
This fixes:
'All user32:TrackMouseEvent tests'
CORE-15686: Gimp 2.8.22 from rapps hangs after startup with 90%-100% CPU usage
and many dupes of that ticket like:
CORE-17551: Ardour hangs at the first start (GTK2 issue)
CORE-15151: newer "Inkscape 0.92.3" is unusable due to WIN32SS message queue lockup
CORE-14086: RawTherapee 5.0-r1-gtk2 fails to start (using 100% CPU)
CORE-11850: Geany 1.28 hangs with endless MsqSendMessage timed out
CORE-8475: Wireshark hangs after launch
It will also slightly appease, but not entirely fix:
CORE-8217: 3D Text ScreenSaver freezes system
