Subject: [RFC PATCH]  iio: Introduce activity channel

This patchset introduces a new interface for supporting some of the composite
sensors in Android [1]. First supported sensors are motion and pedometer.

This is a follow up of the discussion about adding new channels to IIO
initiated some time ago on IIO list [2].

A device that has the motion/pedometer functionality is Freescale's MMA9553L ([3]).

Because we don't have yet the hardware, to demonstrate this new channel we 
update iio_dummy kernel module and iio_event_monitor test program. We want
to get an early feedback about extending the IIO interface in the correct
direction.
