This splits off support for the C23 keywords alignas and alignof,
from the now-deprecated stdalign module. The latter now merely
provides C11 support.
* MODULES.html.sh, NEWS, doc/gnulib.texi:
* doc/posix-headers/stdalign.texi: Document the change.
* lib/stdalign.in.h: Remove most of the definitions (which are now
supplied by the alignasof module), leaving only
__alignas_is_defined and __alignof_is_defined.
* modules/alignasof, modules/alignasof-tests: New files.
* m4/stdalign.m4 (gl_ALIGNASOF): New macro, with
most of the contents of the old gl_STDALIGN_H.
Do not define __alignas_is_defined or __alignof_is_defined.
(gl_STDALIGN_H): Rely on gl_ALIGNASOF for most of the work.
* modules/alignalloc, modules/alignof, modules/argp:
* modules/crypto/md4-buffer, modules/crypto/md5-buffer:
* modules/crypto/sha1-buffer, modules/crypto/sha256-buffer:
* modules/crypto/sha512-buffer, modules/crypto/sm3-buffer:
* modules/fts, modules/rawmemchr, modules/relocatable-prog-wrapper:
* modules/stddef-tests, modules/sys_socket:
Depend on alignasof, not stdalign.
* modules/stdalign: Deprecate. Depend on alignasof.
* modules/stdalign-tests: Move most contents to the new module
alignasof-tests, and depend on that.

* modules/vfprintf-posix (configure.ac): Define GNULIB_VFPRINTF_POSIX.
* modules/vprintf-posix (configure.ac): Define GNULIB_VPRINTF_POSIX.
* lib/stdio.in.h (_GL_ATTRIBUTE_SPEC_PRINTF_STANDARD,
_GL_ATTRIBUTE_SPEC_PRINTF_SYSTEM): New macros.
(_GL_ATTRIBUTE_FORMAT_PRINTF_STANDARD): Renamed from
_GL_ATTRIBUTE_FORMAT_PRINTF. Use _GL_ATTRIBUTE_SPEC_PRINTF_STANDARD.
(_GL_ATTRIBUTE_FORMAT_PRINTF_SYSTEM): Use
_GL_ATTRIBUTE_SPEC_PRINTF_SYSTEM.

* lib/xvasprintf.h: Include <stdio.h>.
(xasprintf, xvasprintf): Use the standard printf format attribute.
* modules/xprintf (Depends-on): List stdio first.
* lib/xprintf.h (xprintf, xvprintf): Use a printf format attribute that
depends on GNULIB_VPRINTF_POSIX.
(xfprintf, xvfprintf): Use a printf format attribute that depends on
GNULIB_VFPRINTF_POSIX.
* modules/c-vasnprintf (Depends-on): Add stdio.
* lib/c-vasnprintf.h: Include <stdio.h>.
(c_vasnprintf): Use the standard printf format attribute.
* modules/c-vasprintf (Depends-on): Add stdio.

(c_asprintf, c_vasprintf): Use the standard printf format attribute.
* modules/c-vsnprintf (Depends-on): Add stdio.
* lib/c-vsnprintf.h: Include <stdio.h>.
(c_vsnprintf): Use the standard printf format attribute.
* modules/c-snprintf (Depends-on): Add stdio.
* lib/c-snprintf.h: Include <stdio.h>.
(c_snprintf): Use the standard printf format attribute.
* modules/c-xvasprintf (Depends-on): Add stdio.
* lib/c-xvasprintf.h: Include <stdio.h>.
(c_xasprintf, c_xvasprintf): Use the standard printf format attribute.
* modules/error (Depends-on): Depend on stdio always.
* lib/error.h: Include <stdio.h>.
(_GL_ATTRIBUTE_SPEC_PRINTF): Remove macro.
(error, error_at_line): Use a printf format attribute that depends on
GNULIB_VFPRINTF_POSIX.
* lib/error.c (_GL_ATTRIBUTE_FORMAT_PRINTF_STANDARD): Renamed from
_GL_ATTRIBUTE_FORMAT_PRINTF.
* modules/verror (Depends-on): Add stdio.
* lib/verror.h: Include <stdio.h>. Don't include "error.h".
(verror, verror_at_line): Use the standard printf format attribute.
* lib/verror.c: Include "error.h".
* modules/argp (Depends-on): Add stdio.
* lib/argp.h (argp_error, __argp_error, argp_failure, __argp_failure):
Use a printf format attribute that depends on GNULIB_VFPRINTF_POSIX.
* modules/libtextstyle-optional (Depends-on): Add stdio.
* lib/textstyle.in.h (ostream_printf, ostream_vprintf): Use the standard
printf format attribute.
* tests/test-nonblocking-misc.h (dbgfprintf): Use the standard printf
format attribute.
Use extern-inline module to declare extern inline functions.
This avoids some bogus warning diagnostics. Problem discovered
when modifying GNU tar to use the manywarnings module.
* lib/argp.h, lib/argp-xinl.c (ARGP_EI) [!_LIBC]:
* lib/argp-fmtstream.h, lib/argp-fs-xinl.c (ARGP_FS_EI) [!_LIBC]:
Define based on extern-inline.
* modules/argp (Depends-on): Add extern-inline.
argp has been leaking memory since commit 79c0a43, in Jul 2006.
* modules/argp (Depends-on): Use dirname-lgpl, not dirname.
* lib/argp-namefrob.h (__argp_base_name): Use last_component, not
base_name, since the latter malloc()s and can call exit().
