Detach an input
Bool DMXRemoveInput(Display *dpy, int id);
DMXRemoveInput() detaches the input device with id, and all associated inputs (e.g., if the id is a backend mouse, and a keyboard is also attached to the backend, then both devices will be detached).
DMXRemoveInput() returns True unless there is a protocol error.
DMXRemoveInput() can generate BadValue (if the id is not valid) and BadAccess (if the input has already been detached).
