This avoids build errors such as:
de@hebrew.po:8192: 'msgstr' is not a valid Shell printf format string, unlike 'msgid'. Reason: This escape sequence is invalid.

Pull in Gnulib fix to allow lib/base64.c to compile using GCC 15 or newer.
Pulled from Gnulib commit 25df6dc425 (Silence some
-Wunterminated-string-initialization warnings.)
GCC 15 adds a new compiler warning "-Wunterminated-string-initialization"
that will trigger what is considered a false-positive in lib/base64.c as
this array is not treated as a string but an array of characters so the
lack of NUL string terminator is expected.
GCC team has added ability to flag such instances of arrays that the
compiler may think are strings as "nonstring" arrays to avoid this
warning: __attribute__((nonstring)).

Correct ntfs_test test failures around attempting to validate attribute
list entries as attributes. The NTFS code uses common logic in some
places to parse both attributes and attribute_lists which complicates
validation. Attribute lists contain different headers including a
different size of the length field (2 bytes) at offset 4 instead of the
4 byte length field used in attributes at offset 4. There are other
differences as well, but attempting to validate attribute list types
using attribute header validation was causing failure of the NTFS test
suite. This change restores some of the validation logic which may be
shared between attributes and attribute lists to be closer to the
original logic prior to fixes for previous CVEs. A following commit will
address some of the implications of removing this validation logic by
correcting some fuzzer failures (some which are exposed by removing the
validation in some of the cases).

Correct ntfs_test test failures around attempting to validate attribute
run list values. The calculation was incorrect for the "curr" variable.
With previous calculation, some file systems would fail validation
despite being well-formed and valid. This was caused by incrementing
"curr" by min_size which included both the (already accounted for)
min_size as well as the size of the run list. Correct by making a new
variable "run_size" to denote the current run list size to increment
both "curr" and "min_size" separately.

A regression was introduced recently as a part of the series of
filesystem related patches to address some CVEs found in GRUB.
This issue may cause either an infinite loop at startup when
accessing certain valid NTFS filesystems, or may cause a crash
due to a NULL pointer dereference on systems where NULL address
is invalid (such as may happen when calling grub-mount from
the operating system level).
Correct this issue by checking that at->attr_cur is within bounds
inside find_attr().
