Ok.  I will still *try* to implement the fourth state, but I will post the
patch as a RFC.  If it is too messy or complex, I will recommend that we
drop it.

I intend to offer the *possibility* of using the HW switch like this on
rfkill-input: on block, block all (EPO).  On unblock, restore previous state
(so, e.g. if WLAN was enabled and bluetooth was disabled, after a HW switch
on/off/on cycle, you will not get bluetooth and WLAN enabled).  But that's
not ready yet, and I am not sure I will be able to do it cleanly.  If I
can't, I will drop it.
