maint.mk: detect incorrect GFDL usage

Similar to the existing sc_GPL_version.  Fortunately, the two licenses
have enough distinction in wording so that neither regexp is a false
positive for the other license.  This won't catch files that line wrap
differently than expected; as it was, the GFDL needed two regexp to
handle the use of GFDL in the m4 project.

* top/maint.mk (_GFDL_regexp, sc_GFDL_version): New rule.

maint.mk: ignore multi-line copyright in NEWS

The old algorithm did not work for projects like m4 that used
long-hand copyright years that wrapped lines.  Meanwhile, this
change has no impact to single-line copyrights, like coreutils.

Changing the rest of the footer, such as bumping from GFDL 1.2
to GFDL 1.3, will still require the developer to rerun
'make update-NEWS-hash' to get the hash back in sync, but that
is probably less frequent.

futimens, utimensat: work around ntfs-3g bug

With ntfs-3g, use of a single UTIME_OMIT failed to make any change
to the remaining two timestamps.  Furthermore, the previous fix
for ctime happens to be specific to xfs, rather than global to
the kernel.  Therefore, to be valid, a cache would have to be
per-device, which gets too expensive, especially considering that
the cost of a preparatory stat pulls the file into kernel cache
to speed up the resulting utimensat.  So, blindly massage UTIME_OMIT
on Linux, even on working filesystems like ext4.

The bugs in xfs and ntfs-3g were reported to the kernel folks,
and fixes written, but it will be several years before gnulib
can assume that file systems in use have picked up the fixes.

* lib/utimensat.c (rpl_utimensat): Drop attempts to cache whether
a ctime bug is present, and expand workaround to cover ntfs-3g.
* lib/utimens.c (fdutimens, lutimens): Likewise.
(utimensat_ctime_really, detect_ctime_bug): Drop cache mechanism.
