Add functionality to query evdev state of a specific key, switch, button,
LED or sound event. This is useful in programs such as powerd
(http://wiki.laptop.org/go/Powerd) which need to query things like the
state of the laptop lid switch from shell code.
Original capture-mode functionality is left unchanged and is still
activated by default. New usage modes are explained in the man page.
