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.

Footprint and Behavior Test for cbprintf variants
#################################################

This ensures that formatted output to the console works as expected with
minimal libc and newlib versions with printk, printf, and cbprintf.

Footprint data can be obtained with:

    for f in sanity-out/*/tests/lib/cbprintf_fp/benchmark.cbprintf_fp.*/build.log ; do
      basename $(dirname $f)
      sed -n '/Memory/,/^\[/p' < $f
    done
