shadow_audit_result for the result argument of audit_logger(). This permits stronger type checking and a better readability of the results (SHADOW_AUDIT_FAILURE/SHADOW_AUDIT_SUCCESS constants). * src/groupadd.c, src/groupdel.c, src/useradd.c, src/userdel.c: Use the SHADOW_AUDIT_FAILURE/SHADOW_AUDIT_SUCCESS results instead of 0 or 1 in audit_logger().
