WIDL used the wrong type information when a pointer to a non-basetype is used as a functions parameter. For example, a 'wchar_t**' would be treated as a 'wchar_t*'.
This patch will be sent upstream.

This fixes display reset transition when an external module acquired
INBV ownership and then released it, similarly to what was done in
commit 0ad65796 for VIDEOPRT.
For this a backup screenbuffer is used to store the contents of the
screen just before an INBV screen acquire transition, and these contents
are restored when it is detected that INBV ownership has been released.
Also, the active text font associated with the active console code-page
is restored, as well as the cursor state and shape.
In addition, any user of BLUE.SYS is now required to explicitly issue
a new IOCTL_CONSOLE_RESET_SCREEN to either enable or disable the screen.
This allows avoiding nasty unwanted screen mode switches when a handle
to the \Device\BlueScreen device is opened but no screen mode switch was
actually wanted - This "fixes" this annoyance on ReactOS and Windows,
when these are running witha VGA-compatible video driver and one wants
to look at properties of the \Device\BlueScreen device using
Sysinternals' WinObj.
Following this, we don't need to check anymore for explicit INBV
ownership by issuing calls to InbvCheckDisplayOwnership(), but instead
we check whether the screen has beeen manually enabled using the
aforementioned IOCTL. This partly supersedes commit 8b553a4b, and allows
fixing the second bug, namely that if we start ReactOS without the
/NOGUIBOOT option (and thus, INBV is active during boot), USETUP would
not show up anything because BLUE.SYS wouldn't display anything on screen.

[USETUP][CONSRV] Call IOCTL_CONSOLE_RESET_SCREEN to tell BlueScreen device to enable the screen.
Rewrite LoadDataFromRegistry() and SaveDataToRegistry() as function helpers. With these, we'll be able to load and save data to registry on our choice.
ExtractIconEx() returns the number of successfully extracted icons from a file. The routine may return 0 in case no icons could be extracted but it could also return 0 if the file is not a valid PE image file or the file couldn't be found.
PrivateExtractIcons and the internal USER32 routine, ICO_ExtractIconExW(), return -1 in such scenarios. The behaviour is correct however we do not want that ExtractIconEx() returns -1 as well as it doesn't comply with the general documentation. In such cases, simply return 0 as no successful icons have been extracted due to related file failures.
