Fix all functional test cases: * use PLO compare,swap,store for atomic instruction * do not use semaphore.h * use xplink flag when linking * scandir implementation * nanosleep implementation * add proctitle * uv_loadavg * uv_fs_event_init/start * uv_fs_event_stop * uv_exepath using __getthent syscall * read free/total memory from mvs data areas * uv_resident_set_memory implementation * network interfaces implementation * cpu_info implementation * implement uv__hrtime * make uv__fs_mkdtemp implementation * epoll implementation for asyncio * uv__fs_event_close implementation * set process title * read ancillary data that remains on queue * ancillary data * implement uv__fs_access * use /dev/urandom for temporary directory name * disable proctitle on zos completely PR-URL: https://github.com/libuv/libuv/pull/1037 Reviewed-By: Saúl Ibarra Corretgé <saghul@gmail.com>
