builtin-am: implement legacy -b/--binary option

The -b/--binary option was initially implemented in 087b674 (git-am: --binary; document --resume and --binary., 2005-11-16). The option will pass the --binary flag to git-apply to allow it to apply binary patches. However, in 2b6eef9 (Make apply --binary a no-op., 2006-09-06), --binary was been made a no-op in git-apply. Following that, since cb3a160 (git-am: ignore --binary option, 2008-08-09), the --binary option in git-am is ignored as well. In 6c15a1c (am: officially deprecate -b/--binary option, 2012-03-13), the --binary option was tweaked to its present behavior: when set, the message: The -b/--binary option has been a no-op for long time, and it will be removed. Please do not use it anymore. will be printed. Re-implement this in builtin/am.c. Signed-off-by: Paul Tan <pyokagan@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
