When a new driver is installed for the same device (like VBoxVideo), it uses the same hardware enum registry key and thus reuses the same DisplayId and the same display registry key. Therefore we need to update the setting in that key, even when the key already exists.
This seems to work good and not cause any issues, but testing indicated that on Windows some values are only updated, when the driver has changed. If neccessary, this can be achieved by updating and querying the ActiveService value in the device enum key (e.g. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_80EE&DEV_BEEF&SUSYS_00000000&REV_00\3&267a616a&0&10\Control: ActiveService). If that doesn't match the current device name (from DriverExtension->RegistryPath) the values should be copied over.
Enter an SEH2_TRY one time and do all testing within it instead of entering the SEH_TRY multiple times.

This is 1:1 the final approved content of #3758, but I committed
by hand and closed the PR to avoid squash+rebase.
in CreateDIBPalette() when passing invalid arguments to CreateDIBSection.
This could be triggered by using the broken test-application "GDIProg".
After this patch not only the BSOD is fixed but also the app does
properly start up, like it is the case on 2k3sp2.

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.
But include registry changes and INF files depending on SARCH variable.
This commit is expected to uncover pc98vid build error on MSVC 2015.

It allows to properly pass the surface handle (and palette entry pointer) from MS ddraw into win32k.
Otherwise, they are passing into the wrong parameters of actual NtGdi* function, and due to this,
since they're detected as invalid, they become NULL, and that function does not work correctly.
See https://docs.microsoft.com/en-us/windows/win32/devnotes/-dxgkernel-ntgdiddgetdc for the reference
(and confirmed by our headers).
Required by MS DirectDraw stack (ddraw.dll & dxg.sys).
