[ros-diffs] [mjmartin] 41119: - i8042MouInternalDeviceControl: Implement IoControlCode of IOCTL_INTERNAL_I8042_HOOK_MOUSE. - ForwardIrpAndWait: Don't use IoForwardIrpSynchronously to Forward IRPs as it fails if no next stack location is available, which prevents the mouse from initializing. Changed it to match implementation of our other input drivers. Mouse pointer now works with VBoxMouse driver loaded.
