add two hack so dxg.sys continue works for now. 
it does not longer crash at DdDeleteDirectDrawObject for it never been call longer to dxg.sys until I figout why
take DxEngLockShareSem and DxEngUnLockShareSem offline need more invigaste how it is done in windows. 
take DxGdiDdGetScanLine offline for now so it does not crash dxg.sys
