Fedora 39 getxattr with XATTR_NAME_POSIX_ACL_ACCESS either
succeeds or fails with ENODATA, so it is no longer possible to
detect from its failure that the filesystem might support NFSv4 ACLs.
Problem reported by Ondrej Valousek in:
https://lists.gnu.org/r/bug-gnulib/2023-04/msg00228.html
Instead, use listxattr to determine whether NFSv4 ACLs are in play.
This typically saves syscalls anyway.
* lib/file-has-acl.c: In #if, use (HAVE_LINUX_XATTR_H &&
HAVE_LISTXATTR) instead of GETXATTR_WITH_POSIX_ACLS.
The following changes apply when (USE_ACL && HAVE_LINUX_XATTR_H &&
HAVE_LISTXATTR):
Include minmax.h.
(have_xattr): New function.
(file_has_acl): Try listxattr first; typically this means we need
to do no other syscall. Call getxattr only if there are NFSv4
ACLs but not POSIX ACLs.
* m4/acl.m4 (gl_FILE_HAS_ACL): Simplify by merely testing for
linux/xattr.h and listxattr. All uses changed.

Remove year2038-required and largefile-required, replacing
the former with year2038-recommended and simply removing
the latter. This syncs with Autoconf master.

if AC_SYS_YEAR2038_RECOMMENDED is not defined, rather than if
AC_SYS_LARGEFILE_REQUIRED is not defined.
* modules/largefile-required, modules/year2038-required: Removed.
* modules/year2038: Do not depend on largefile; simply
use m4/largefile.m4, since we shouldn’t need the extra goodies
largefile supplies.

Without this patch, building coreutils with
--enable-gcc-checking=expensive would fail with a message like
“lib/exclude.c:682:6: error: leak of FILE 'in' [CWE-775]
[-Werror=analyzer-file-leak]”, because Gnulib replaced fclose but
not fopen, and GCC saw a call to fopen followed by a call to
rpl_fclose. The patch causes GCC to instead see a call to
rpl_fopen followed by rpl_fclose.
* m4/fclose.m4 (gl_FUNC_FCLOSE): Replace fopen when replacing
fclose.

Rewrite commentary to not mention Autoconf 2.72, as the plan is to
jump from 2.71 to 2.73 with no 2.72. Leave code uses of
‘m4_version_prereq([2.72], ...)’ alone, though as they’re still
correct for Autoconf released versions and will help test Autoconf
release candidates.
