Problem reported by Bernhard Voelker in
<http://lists.gnu.org/archive/html/bug-gnulib/2013-04/msg00071.html>.
I don't know whether this patch fixes that race condition, but it
fixes *some* race conditions, so it should be a win.

* modules/utimensat-tests (Depends-on):
Depend on nanosleep, not usleep.
* modules/chown-tests (test_chown_LDADD):
* modules/lchown-tests (test_lchown_LDADD):
* modules/stat-time-tests (test_stat_time_LDADD):
New macro.
* modules/fchownat-tests (test_fchownat_LDADD):

* modules/futimens-tests (test_futimens_LDADD):
* modules/utimens-tests (test_utimens_LDADD):
* modules/utimensat-tests (test_utimensat_LDADD):
Add $(LIB_NANOSLEEP).
* modules/stat-time-tests (Files): Add tests/nap.h.
* tests/nap.h: Include <limits.h>, for INT_MAX.
(lt_mtime): Remove.
(diff_timespec): New function.
(get_stat): Rename from get_mtime. All callers changed.
(nap_works): Determine the needed delay by inspecting the
file system's timestamp jumps; this should be more reliable.
Look at both mtime and ctime, and take the maximum of the two jumps.
(nap_works, guess_delay):
Return a nanosecond cound, not a microsecond count.
All callers changed.
(nap_works, nap): Use nanosleep, not usleep. Check for nanosleep
failure.
(nap): Multiply the guess by 1.125, to accommodate the case where
the file system's clock is a bit slower than nanosleep's clock.
* tests/test-stat-time.c (BASE): New macro.
Include nap.h.
(nap): Remove; nap.h now defines this. This removes a duplicate
implementation of 'nap'.

* modules/stat-time-tests (configure.ac): Use AC_CHECK_FUNCS_ONCE.
* tests/test-stat-time.c (nap): Separate assignment from call.
Suggested by Paolo Bonzini and Bruno Haible.
