vasnprintf-gnu: New module.

Suggested by Eric Blake in
<https://lists.gnu.org/archive/html/bug-gnulib/2023-03/msg00060.html>.

* lib/printf-parse.c (PRINTF_PARSE): Recognize the 'B' conversion.
* lib/printf-parse.h: Update comments.
* lib/wprintf-parse.h: Likewise.
* lib/vasnprintf.c (MAX_ROOM_NEEDED): Treat the 'B' conversion like 'b'.
(VASNPRINTF): Implement 'B' conversion if
NEED_PRINTF_DIRECTIVE_UPPERCASE_B is set. Support the 'B' conversion if
requested.
* m4/printf.m4 (gl_PRINTF_DIRECTIVE_B): When cross-compiling, guess yes
on glibc >= 2.35.
(gl_PRINTF_DIRECTIVE_UPPERCASE_B): New macro.
* m4/vasnprintf.m4 (gl_PREREQ_VASNPRINTF_WITH_POSIX_EXTRAS): Renamed
from gl_PREREQ_VASNPRINTF_WITH_EXTRAS.
(gl_PREREQ_VASNPRINTF_DIRECTIVE_UPPERCASE_B,
gl_PREREQ_VASNPRINTF_WITH_GNU_EXTRAS): New macros.
* m4/vasnprintf-posix.m4 (gl_FUNC_VASNPRINTF_IS_POSIX): New macro,
extracted from gl_FUNC_VASNPRINTF_POSIX.
(gl_FUNC_VASNPRINTF_POSIX): Require it. Invoke
gl_PREREQ_VASNPRINTF_WITH_POSIX_EXTRAS.
* m4/vasnprintf-gnu.m4: New file.
* modules/vasnprintf-gnu: New file.
* modules/c-vasnprintf (configure.ac): Update.
* modules/unistdio/u8-vasnprintf (configure.ac): Likewise.
* modules/unistdio/u8-u8-vasnprintf (configure.ac): Likewise.
* modules/unistdio/u16-vasnprintf (configure.ac): Likewise.
* modules/unistdio/u16-u16-vasnprintf (configure.ac): Likewise.
* modules/unistdio/u32-vasnprintf (configure.ac): Likewise.
* modules/unistdio/u32-u32-vasnprintf (configure.ac): Likewise.
* modules/unistdio/ulc-vasnprintf (configure.ac): Likewise.

+Description:
+POSIX and GNU compatible vsprintf with automatic memory allocation and bounded
+output size.
+
+Comment:
+This module should not be used as a dependency from a test module,
+otherwise when this module occurs as a tests-related module, it will
+have side effects on the compilation of the 'vasnprintf' module, if
+that module occurs among the main modules in lib/.
