[Bug-tar] [PATCH 2/3] tar: set stdin/stdout to binary mode correctly with binary-io

[KO Myung-Hun]

* gnulib.modules: Add binary-io.
* src/buffer.c (_open_archive): Ensure that stdin is binary mode
before check_compressed_archive(). Set stdout to binary mode if
writing archives to stdout.
* src/common.h: Include binary-io.h
* src/extract.c (extract_file): Set stdout to binary mode if
writing to stdout.
* src/misc.c (xpipe): Set pipes to binary mode
* src/system.c (sys_child_open_for_compress): Set stdout to binary
mode.
(sys_child_open_for_uncompress): Set stdin to binary mode.
