CI timeout + line-info in releases (#279)

* Update perfetto args.gn.in - remove enable_perfetto_tools_trace_to_text (unused) * core timeout implementation - requires OMNITRACE_CI=ON - requires OMNITRACE_CI_TIMEOUT=<sec> - adds pthread_self and std::this_thread::get_id to thread info - pthread_create_gotcha stores native handles (pthread_self) * Testing updates - improve detection of segfault/failures with PASS_REGEX exists - add OMNITRACE_CI_TIMEOUT env variable to all tests * Line-info in releases - e.g. -g1 + more options to minimize size of debug info * Fix typo in config exit action message * OMNITRACE_UNLIKELY around debug/verbose messages * format fixes * Overflow tests + capability check * transpose example update - link to threads library * roctracer/rocprofiler update - in ROCm 5.5.0, cannot include rocprofiler.h and roctracer.h in same file due to conflicting enum defs - Moved HSA tracing setup/shutdown to component::roctracer * roctracer update - fix definition of roctracer::setup when disabled * Update fork example - detach threads on main PID - flush io outputs when printing info * Update overflow tests - pass regular expressions - overflow on PERF_COUNT_SW_CPU_CLOCK event * fork gotcha update - use getpid() instead of getppid() * update fork example - wait on threads calling fork * timeout update - wait on timeout thread to launch before proceeding
