Eugene Syromyatnikov 9c8ec0a80f Print microseconds/nanoseconds as non-negative
Negative micro/nanoseconds values are treated as invalid by kernel
anyway, and in one case (timespec_valid in include/linux/time.h)
it is even checked by conversion to unsigned long.

* print_timespec.c (timespec_fmt): Change tv_sec format to %lld and
tv_nsec format to %llu.
(print_timespec_t): Cast tv_sec to long long and process tv_nsec with
zero_extend_signed_to_ull.
(sprint_timespec): Likewise.
* print_timeval.c (timeval_fmt): Change tv_sec format to %lld and
tv_usec format to %llu.
(print_timeval_t): Cast tv_sec to long long and process tv_nsec with
zero_extend_signed_to_ull.
(sprint_timeval, print_timeval32_t, sprint_timeval32): Likewise.
* defs.h (TIMESPEC_TEXT_BUFSIZE): Update.
* tests/adjtimex.c (main): Change tv_sec printing format to %lld, cast
it to long long; change tv_usec printing format to %llu, process it with
zero_extend_signed_to_ull.
* tests/clock_nanosleep.c (main): Change tv_sec printing format to %lld,
cast it to long long; change tv_nsec printing format to %llu, process it
with zero_extend_signed_to_ull.
* tests/clock_xettime.c (main): Likewise.
* tests/futex.c (main): Likewise.
* tests/futimesat.c (print_tv): Likewise.
* tests/getrusage.c (invoke_print): Likewise.
* tests/mq_sendrecv.c (do_send, do_recv, main): Likewise.
* tests/nanosleep.c (main): Likewise.
* tests/pselect6.c (main): Likewise.
* tests/restart_syscall.c (main): Likewise.
* tests/rt_sigtimedwait.c (iterate, main): Likewise.
* tests/sched_rr_get_interval.c (main): Likewise.
* tests/semop.c (main): Likewise.
* tests/timer_xettime.c (main): Likewise.
* tests/timerfd_xettime.c (main): Likewise.

* tests/wait4.c (sprint_rusage): Likewise.
* tests/waitid.c (sprint_rusage): Likewise.
* tests/utimensat.c (print_ts): Likewise.
(main): Add check for higher bits of tv_sec/tv_nsec.
