imp 67b935fa34 Create a sysctl kern.cam.{,a,n}da.X.invalidate ... kern.cam.{,a,n}da.X.invalidate=1 forces *daX to detach by calling cam_periph_invalidate on the underlying periph. This is for testing purposes only. Include only with options CAM_TEST_FAILURE and rename the former [AN]DA_TEST_FAILURE, and fix nda to compile with it set. We're using it at work to harden geom and the buffer cache to be resilient in the face of drive failure. Today, it far too often results in a panic. While much work was done on SIM initiated removal for the USB thumnb drive removal work, little has been done for periph initiated removal. This simulates what *daerror() does for some errors nicely: we get the same panics with it that we do with failing drives.
