utimens: add lutimens interface Wraps utimensat(,AT_SYMLINK_NOFOLLOW) or lutimes, when supported; otherwise fail with ENOSYS. Allows coreutils' copy.c to preserve symlink timestamps on more systems. Note that cygwin's lstat changes atime of symlinks, but mtime can reliably be set. * lib/utimens.c (lutimens): New function. * m4/utimens.m4 (gl_UTIMENS): Check for lutimes. * lib/utimens.h (lutimens): Declare new interface. * tests/test-utimens.c (main): Enhance test. * tests/test-lutimens.h (test_lutimens): New file. * modules/utimens-tests (Files): Distribute it. (Depends-on): Add symlink. (configure.ac): Check for usleep. Signed-off-by: Eric Blake <ebb9@byu.net>
