utimes("file/",times) mistakenly succeeds. This commit doesn't fix
utimes, but does make utimensat be careful before calling utimes.
The test is now enhanced to test trailing slashes and directories.
Meanwhile, cygwin 1.5 stat() on a directory changes atime (it does
a readdir under the hood to populate st_nlink), so only mtime of
a directory is reliable enough for testing. Cygwin 1.7 no longer
has this problem, because it no longer wastes time on st_nlink.

Coreutils new 'touch -h' is easier to write if we guarantee POSIX
semantics of utimensat(fd,"file",NULL,AT_SYMLINK_NOFOLLOW), rather
than blindly failing with ENOSYS even on non-symlinks.
* lib/utimens.c (lutimens): Fall back to utimens rather than
failing with ENOSYS, when file is not a symlink.
(utimens): Reduce redirection.

non-symlinks.

symlinks.

ext4 on an alpha system has a quantization of about 10 ms but
a resolution of 1ns; utimecmp does not know about quantization,
so tests were failing when comparing timestamps that fall
within the same quantization window. Add strategic usleeps
throughout to minimize this issue, whether or not we later
improve utimecmp to account for quantization.
Windows (and hence cygwin) is documented as having a default
clock quantization of 15.25 milliseconds (although it can be
reduced to 1 millisecond); file timestamps are quantized to this
boundary even though more accurate timing can be obtained.
However, this means that 15 milliseconds is too short for any
test that wants to guarantee crossing a file timestamp boundary.
Cygwin, however, still has bugs where clock_gettime can lag
behind file timestamps, which is not fixed by this patch.
Solaris 9 with NFS exposed the same problem for futimes that was
previously fixed for utimes on Solaris 8, where futimens(f,NULL)
uses a different time source than futimes(,{,UTIME_NOW}).
* tests/test-stat-time.c (nap): Lengthen delay to 20ms, for
ext4 on alpha, and for cygwin.
* tests/test-utimens-common.h: New file.
(nap): Factor delays into single function.
* tests/test-lutimens.h (test_lutimens): Use new header.
* tests/test-futimens.h (test_futimens): Likewise.
* tests/test-utimens.h (test_utimens): Likewise. Also, force NFS
timestamps to occur from same machine, as was done previously for
test_utimens.
* modules/utimens-tests (Files): Ship new file.

Testing on Solaris 8 with NFS: creat() and utimens(,NULL) seem to
set timestamps according to the current time on the server, while
utimens(,{,UTIME_NOW}) sets timestamps according to the current
time on the client. If two machines are not perfectly
synchronized in time, then this makes time appear to move
backwards. Avoid spurious test failures caused by a mtime
comparison across machines, by instead doing 2 mtime comparisons,
each known to be from timestamps tied to a single machine.
* tests/test-utimens.h (test_utimens): Add a utimens call prior to
grabbing stat buffer.
