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)).

In the function merge_state_with_log(), memory is allocated for the variable
next_nodes when creating a union of the variables table_nodes and log_nodes.
However, if next_state->entrance_nodes is NULL, then table_nodes becomes NULL
and we still allocate memory to copy the content of log_nodes. This can cause
a resource leak since we only free the memory for next_nodes if table_nodes
isn't NULL. To prevent this, we need to check that next_state->entrance_nodes
isn't NULL before allocating memory for the union.

Originally added in commit db7337a3d (grub-core/lib/posix_wrap/stdlib.h
(abort): Removed), this patched out all relevant invocations of abort()
in gnulib. While it was not documented why at the time, testing suggests
that there's no abort() implementation available for gnulib to use.
gnulib's position is that the use of abort() is correct here, since it
happens when input violates a "shall" from POSIX. Additionally, the
code in question is probably not reachable. Since abort() is more
friendly to user-space, they prefer to make no change, so we can just
carry a define instead (suggested by Paul Eggert).

Originally added in commit 9fbdec2f (bootstrap: Add gnulib's base64
module) and subsequently modified in commit 552c9fd08 (gnulib: Fix build
of base64 when compiling with memory debugging), fix-base64.patch
handled two problems we have using gnulib, which are exercised by the
base64 module but not directly caused by it.
First, GRUB defines its own bool type, while gnulib expects the
equivalent of stdbool.h to be present. Rather than patching gnulib,
instead use gnulib's stdbool module to provide a bool type if needed
(suggested by Simon Josefsson).
Second, our config.h doesn't always inherit config-util.h, which is
where gnulib-related options like _GL_ATTRIBUTE_CONST end up.
fix-base64.h worked around this by defining the attribute away, but this
workaround is better placed in config.h itself, not a gnulib patch.

This is a really minor issue where a variable is being assigned to but
not checked before it is overwritten again.
The reason for this issue is that we are not building with DEBUG set and
this in turn means that the assert() that reads the value of the

The solution, move the assignment to match_last in to an ifdef DEBUG too.

The upcoming support for LUKS2 disc encryption requires us to include a
parser for base64-encoded data, as it is used to represent salts and
digests. As gnulib already has code to decode such data, we can just
add it to the boostrapping configuration in order to make it available
in GRUB.
The gnulib module makes use of booleans via the <stdbool.h> header. As
GRUB does not provide any POSIX wrapper header for this, but instead
implements support for bool in <sys/types.h>, we need to patch
base64.h to not use <stdbool.h> anymore. We unfortunately cannot include
<sys/types.h> instead, as it would then use gnulib's internal header
while compiling the gnulib object but our own <sys/types.h> when
including it in a GRUB module. Because of this, the patch replaces the
include with a direct typedef.
A second fix is required to make available _GL_ATTRIBUTE_CONST, which
is provided by the configure script. As base64.h does not include
<config.h>, it is thus not available and results in a compile error.
This is fixed by adding an include of <config-util.h>.

Upgrade Gnulib files to 20190105.
It's much easier to maintain GRUB's use of portability support files
from Gnulib when the process is automatic and driven by a single
configuration file, rather than by maintainers occasionally running
gnulib-tool and committing the result. Removing these
automatically-copied files from revision control also removes the
temptation to hack the output in ways that are difficult for future
maintainers to follow. Gnulib includes a "bootstrap" program which is
designed for this.
The canonical way to bootstrap GRUB from revision control is now
"./bootstrap", but "./autogen.sh" is still useful if you just want to
generate the GRUB-specific parts of the build system.
GRUB now requires Autoconf >= 2.63 and Automake >= 1.11, in line with
Gnulib.
Gnulib source code is now placed in grub-core/lib/gnulib/ (which should
not be edited directly), and GRUB's patches are in
grub-core/lib/gnulib-patches/. I've added a few notes to the developer
manual on how to maintain this.
