to avoid manual calculation of min and max values and fix coccinelle warnings such WARNING opportunity for min()/max() adding one common definition that could be used in multiple files under selftests. there are also some defines for min/max scattered locally inside sources under selftests. this also prepares for cleaning up those redundant defines and include kselftest.h instead.

changes in v2: redefine min/max in a more strict way to avoid signedness mismatch and multiple evaluation. is_signed_type() moved from selftests/kselftest_harness.h to selftests/kselftest.h.

Heh, reminds me of https://xkcd.com/927.
All of these #defines are available in tools/include/linux/kernel.h, and it's trivially easy for selftests to add all of tools/include to their include path. I don't see any reason for the selftests framework to define yet another version, just fix the individual tests.
