__obstack_printf_chk): New prototypes.
	(__vasprintf_chk, __vdprintf_chk,
	__obstack_vprintf_chk): Likewise.
	Add libc_hidden_proto.
	* libio/obprintf.c
	(_IO_obstack_jumps): No longer static, add attribute_hidden.
	* libio/bits/stdio-ldbl.h (__asprintf_chk, __dprintf_chk,
	__obstack_printf_chk, __vasprintf_chk, __vdprintf_chk,
	__obstack_vprintf_chk): Add __LDBL_REDIR_DECL.
	* libio/bits/stdio2.h (__asprintf_chk, __dprintf_chk,
	__obstack_printf_chk, __vasprintf_chk, __vdprintf_chk,
	__obstack_vprintf_chk): New prototypes.
	(asprintf, __asprintf, dprintf, obstack_printf, vasprintf, vdprintf,
	obstack_vprintf): New inlines.
	* debug/dprintf_chk.c: New file.
	* debug/vdprintf_chk.c: New file.
	* debug/asprintf_chk.c: New file.
	* debug/vasprintf_chk.c: New file.
	* debug/obprintf_chk.c: New file.
	* debug/tst-chk1.c (do_test): Add asprintf and obstack_printf tests.
	* debug/Versions (__asprintf_chk, __dprintf_chk, __obstack_printf_chk,
	__vasprintf_chk, __vdprintf_chk, __obstack_vprintf_chk): Export
	@@GLIBC_2.8.
	* debug/Makefile: Build asprintf_chk, vasprintf_chk, dprintf_chk,
	vdprintf_chk and obprintf_chk, set CFLAGS for them.
	* sysdeps/ieee754/ldbl-opt/nldbl-compat.c (__nldbl___vasprintf_chk,
	__nldbl___vdprintf_chk, __nldbl___obstack_vprintf_chk): Add
