Add unit tests for utility functions in src/utils.c using the Check testing framework. The tests verify parse_cpu_set(), strtoi(), and parse_prio() functions. Unit tests are built conditionally when libcheck is available. Run tests with 'make unit-test'. The test framework uses the Check library which provides process isolation for each test, preventing failures in one test from affecting others.
