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 events with no associated device structure are valid. Handle them
in the sample by printing NULL instead of crashing trying to lookup the
device name.

Add an initial board overlay in the input_dump directory for testing
zephyr,gpio-keys. This takes the exsiting "gpio-keys" node, changes the
compatible to the one used by the gpio keys input driver and set some
codes.

Add a first input sample in the subsys/input directory. This just prints
any input event on the console.
