Adds an option to output the results of iptables-save,
ip6tables-save, and xtables-save save to a file.
Updates the man page with this new option.
Uses the dup2 call to replace stdout with the specified file.
Error output is unchanged.
This is a feature requested by a Gentoo developer in
Bugzilla #905.

When an unknown option is given, iptables-restore should exit instead of
continue its operation. For example, if `--table` was misspelled, this
could lead to an unwanted change. Moreover, exit with a status code of
1. Make the same change for iptables-save.
OTOH, exit with a status code of 0 when requesting help.

Static variables are initialized to zero by default, so remove explicit
initalization. This patch fixes the checkpatch issue.

On glibc, <sys/errno.h> is a synomym for <errno.h>.
<errno.h> is specified by POSIX, so use that.
Fixes compilation error with musl libc

It's not required and breaks on static-only uClibc builds which don't
have the header file.

Command used:
git grep -f <(pcregrep -hior
'(?<=#define\s)IP6?(T_\w+)(?=\s+X\1)' include/)
and then fix all occurrences.

No real API/ABI change incurred, since the definition of the structs'
types is not visible anyhow.
