Add Shared memory service to access RTX devices from Windows environment

Windows applications may access cifX devices which are under RTX control via a special shared memory extension. This extension consists of a RTX process “cifXd” and two libraries for the RTX (“cifX32Dll.rtdll”) and Windows environment (“cifX32Dll.dll”). The cifXd process has exclusive control on the cifX devices and provides a shared memory interface to enable access from various RTX and Windows applications. A RTX and a Windows version of the cifX32Dll library allow any CIFX-API compatible application to access the cifXd-controlled devices via the shared memory interface.
