vt(4): Add cngrab() and cnungrab() callbacks
They are used when a panic occurs or when entering a DDB session for
instance.
cngrab() forces a vt-switch to the console window, no matter if the
original window is another terminal or an X session. However, cnungrab()
doesn't vt-switch back to the original window currently.
