obstack-printf-gnu: New module.

Browse Source 
* m4/obstack-printf-posix.m4 (gl_FUNC_OBSTACK_PRINTF_IS_POSIX): New
macro, extracted from gl_FUNC_OBSTACK_PRINTF_POSIX.
(gl_FUNC_OBSTACK_PRINTF_POSIX): Require it. Invoke
gl_PREREQ_VASNPRINTF_WITH_POSIX_EXTRAS.
* m4/obstack-printf-gnu.m4: New file, based on
m4/obstack-printf-posix.m4.
* modules/obstack-printf-gnu: New file, based on modules/vasnprintf-gnu.
* doc/glibc-functions/obstack_printf.texi: Mention the new module.
* doc/glibc-functions/obstack_vprintf.texi: Likewise.

Description:
POSIX and GNU compatible formatted printing into an obstack.
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/.
