Introduce IIO interface for Android advanced features

This patchset introduces a new interface for supporting some of the composite
sensors in Android [1]. First supported sensors are activity 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 activity/pedometer functionality is Freescale's MMA9553L ([3]).

Because we don't have yet the hardware, to demonstrate these new channels 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.

Changes since v3:
	* rebased on latest togreg branch (head at 5e62863aea)
	* fix typos reported by Hartmut

Changes since v2: (comments from Jonathan and Hartmut)
	* dropped the RFC tag
	* use int instead of unsigned long for ret in iio_evgen_poke
	* remove TRANSITION event and use THRESHOLD instead
	* remove IIO_HEIGHT channel and use CALIBHEIGHT mask instead
	* adapt iio_dummy modules and iio_event_monitor to reflect IIO
	  interface changes.
