selftests: add kselftest framework for uniform test reporting
Add kselftest framework for tests to use. This is a light weight framework provides a set of interfaces to report test results. Tests can use these interfaces to report pass, and fail cases as well as when failure is due to configuration problems such as missing modules, or when a test that is should fail, fails as expected, and a test that should fail, passes. The framework uses POSIX standard return codes for reporting results to address the needs of users that want to run the kernel selftests from their user-space test suites and want to know why a test failed. In addition, the framework includes interfaces to use to report test statistics on number of tests passed and failed. Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
