Keith Packard 0b90fd5adf samples, tests, boards: Switch main return type from void to int
As both C and C++ standards require applications running under an OS to
return 'int', adapt that for Zephyr to align with those standard. This also
eliminates errors when building with clang when not using -ffreestanding,
and reduces the need for compiler flags to silence warnings for both clang
and gcc.

Most of these changes were automated using coccinelle with the following
script:

@@
@@
- void
+ int
main(...) {
	...
-	return;
+	return 0;
	...
}

Approximately 40 files had to be edited by hand as coccinelle was unable to
fix them.

Input Dump
##########

Overview
********

The Input Dump sample prints any input event using the :ref:`input` APIs.

Requirements
************

The samples works on any board with an input driver defined in the board devicetree.

Building and Running
********************

Build and flash as follows, changing ``nrf52dk_nrf52832`` for your board:

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/input/input_dump
   :board: nrf52dk_nrf52832
   :goals: build flash
   :compact:

After starting, the sample will print any input event in the console.
