Move these functions to helpers.h to enable reuse across tests, eliminating around 250 lines of duplicate code. Converge the error handling by using ksft_exit_fail_msg(), which is functionally equivalent with err() within the selftest framework. This change is a prerequisite for the upcoming xstate selftest, which requires signal handling for registering and cleaning up handlers. Signed-off-by: Chang S.
