sysconf(_SC_NPROCESSORS_CONF) (via get_nprocs_conf) reflects
cpu_possible_mask, which is fixed at boot time, so querying it
repeatedly is unnecessary.
Replace multiple calls to sysconf(_SC_NPROCESSORS_CONF) with a single
global nr_cpus variable initialized once at startup.
`#pragma once` in timerlat_u.h is needed for pre-C23 compilers to avoid
redefinition errors.

tools/rtla: Add unit tests for utils.c2026-03-04T14:51:56ZCosta Shulyupincosta.shul@redhat.com2026-01-19T10:58:57Zurn:sha1:3a4080e5e426352a78f944db0ff29e029d89193b
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.
