dd 3e96616fd4 Add an -S option that allows the user to disable vty switching. It is
implemented using a new VT_LOCKSWITCH ioctl.  Although it is possible
to implement something like this by VT_SETMODEing to VT_PROCESS and
never releasing the vty, that method has a number of downsides, the
biggest of which is that some program has to stay resident for the
lock to be in effect.
