Add LFS support for fts functions (bug 11460)

fts didn't have large-file support yet and fts.h had an #error preventing
usage when _FILE_OFFSET_BITS was set. This required nasty workarounds for
programs using fts with LFS. This patch implements LFS support for fts by
adding FTS64 and FTENT64 variants plus fts64 functions. Which are simple
aliases for 64bit off_t arches.

Also includes a simple testcase for some of the fts functions with or
without LFS enabled.

	[BZ #11460]
	* io/Makefile (routines): Add fts64.
	(tests): Add tst-fts and tst-fts-lfs.
	(CFLAGS-fts64.c): New.
	* io/Versions (GLIBC_2.23): New.
	* io/fts.c: Replace FTS with FTSOBJ, FTSENT with FTSENTRY. Use
	function defines FTS_OPEN, FTS_CLOSE, FTS_READ, FTS_SET and
	FTS_CHILDREN. Define FTSOBJ, FTSENTRY, FTS_OPEN, FTS_CLOSE,
	FTS_READ, FTS_SET, FTS_CHILDREN, INO_T, STAT and LSTAT if necessary.
	* io/fts.h (FTS64): New if _USE_LARGEFILE64.
	(FTSENT64): Likewise.
	(fts64_children): Likewise.
	(fts64_close): Likewise.
	(fts64_open): Likewise.
	(fts64_read): Likewise.
	(fts64_set): Likewise.
	* io/fts64.c: New file.
	* io/tst-fts.c: New test.
	* io/tst-fts-lfs.c: Likewise.
	* sysdeps/unix/sysv/linux/aarch64/libc.abilist (GLIBC_2.23): Add
	GLIBC_2.23, fts64_children, fts64_close, fts64_open, fts64_read and
	fts64_set.
