Measuring particulate matter in ug / m3 (micro-grams per cubic meter)
is de facto standard. Existing air quality sensors usually follow
this convention and are capable of returning measurements using
this unit.
IIO currently does not offer suitable channel type for this
type of measurements hence this patch adds this.
In addition, extra modifiers are introduced used for distinguishing
between fine pm1, pm2p5 and coarse pm4, pm10 particle measurements, i.e
IIO_MOD_PM1, IIO_MOD_PM25 and IIO_MOD_PM4, IIO_MOD_PM10.
pmX consists of particles with aerodynamic diameter less or equal to
X micrometers.

Add new channel type support for phase.
This channel may be used by Time-of-flight sensors to express the
phase difference between emitted and received signals. Those sensor
will then use the phase shift of return signals to approximate the
distance to objects.

Add new channel type for relative position on a pad.
These type of analog sensor offers the position of a pen
on a touchpad, and is represented as a voltage, which can be
converted to a position on X and Y axis on the pad.
The channel will hand the relative position on the pad in both directions.
The channel can then be consumed by a touchscreen driver or
read as-is for a raw indication of the touchpen on a touchpad.

Add new channel types support for gravity sensor.
Gravity sensor provides an application-level or physical collection that
identifies a device that measures exclusively the force of Earth's
gravity along any number of axes.

Refactor the code in print_event() to reduce code duplication and better
reflect that the type is output unconditionally, as well as cascade the
dependency of the diff-channel. Saves a few lines of code, as well.

The man-page of errno states, that errno should be saved before doing any
library call, as that call may have changed the value of errno. So, when
encountering any error, save errno first.
This patch affects generic_buffer.c, iio_event_monitor.c and iio_utils.c.

Definition of _GNU_SOURCE is needed to get rid of some warnings, such
as:
warning: implicit declaration of function `asprintf'.
generic_buffer.c and iio_event_monitor.c define _GNU_SOURCE,
but it is also needed in lsiio.c and iio_utils.c. For this reason,
this patch adds the definition in Makefile and removes it from where
it already exists.
