I also needed to add a mflag.IsSet() function that allows you to check
to see if a certain flag was actually specified on the cmd line.
Per #9221 - also tweaked the docs to fix a typo.
Closes#9221

pkg/archive contains code both invoked from cli (cross platform) and
daemon (linux only) and Unix-specific dependencies break compilation on
Windows. We extracted those stat-related funcs into platform specific
implementations at pkg/system and added unit tests.

Some parts of pkg/archive is called on both client/daemon code. To get
it compiling on Windows, these funcs are extracted into files with
build tags.

SIGCHLD and SIGWINCH used in api/client (cli code) are not
available on Windows. Extracting into separate files with build
tags.

The current Dev version of TarSum includes hashing of extended
file attributes and omits inclusion of modified time headers.
I refactored the logic around the version differences to make it
more clear that the difference between versions is in how tar
headers are selected and ordered.
TarSum Version 1 is now declared with the new Dev version continuing
to track it.

This re-applies commit b39d02b with additional iptables rules to solve the issue with containers routing back into themselves.
The previous issue with this attempt was that the DNAT rule would send traffic back into the container it came from. When this happens you have 2 issues.
1) reverse path filtering. The container is going to see the traffic coming in from the outside and it's going to have a source address of itself. So reverse path filtering will kick in and drop the packet.
2) direct return mismatch. Assuming you turned reverse path filtering off, when the packet comes back in, it's goign to have a source address of itself, thus when the reply traffic is sent, it's going to have a source address of itself. But the original packet was sent to the host IP address, so the traffic will be dropped because it's coming from an address which the original traffic was not sent to (and likely with an incorrect port as well).
The solution to this is to masquerade the traffic when it gets routed back into the origin container. However for this to work you need to enable hairpin mode on the bridge port, otherwise the kernel will just drop the traffic.
The hairpin mode set is part of libcontainer, while the MASQ change is part of docker.
This reverts commit 63c303eecdbaf4dc7967fd51b82cd447c778cecc.

By default is a demo of file differences, but can be used to create a
tar of changes between an old and new path.
