* Update struct DevRec methods to take a "void *" parameter since they get called with different xxxInterface records depending on whether they are a keyboard, mouse, or display. Introduce GenericReturnVoid method implementation for use where needed with DevRec methods. (see mouseif.c) * Cast functions implementing DevRec methods as appropriate to match the method signature. * Update struct DspInterfaceRec methods cleardisplay, bitblt_to_screen, mouse_invisible, and mouse_visible to declare the parameters they require and all return unsigned long results (though it's not clear that this is actually the correct type). Requires updating dosmouse.c method implementations. * Update GenericReturnT and GenericPanic method implementations to have the signature required by the method slots they are used in. * Correct DOS-only section with incorrect arguments to device.exit call for the mouse. * Use include "dspifdefs.h" for prototypes for GenericReturnXXX method implementations.
