Linus Walleij 672f93b604 iio: event_monitor: report unsupported events
This makes the event monitor bail out with a helpful error
message if a device does not support events, as a related
fix to iio core now makes it return -ENODEV properly.

Hartmut Knaack 916e89e4b7 tools:iio:iio_event_monitor: refactor events output
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.

Hartmut Knaack 2b6a6e67af tools:iio: save errno first
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.

Roberta Dobrescu 976d9ab112 tools: iio: Define _GNU_SOURCE in Makefile
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.
