Show a basic example of how unit testing can be applied for the coreboot project. Add a test harness for lib/string.c module. TEST=Install cmocka via appropriate command: sudo apt-get install -y libcmocka-dev sudo emerge dev-util/cmocka yum install libcmocka-devel * Build and run unit tests via `make unit-tests` * Check the output to see that tests passed.
