Adds support for the daemon to handle user namespace maps as a
per-daemon setting.
Support for handling uid/gid mapping is added to the builder,
archive/unarchive packages and functions, all graphdrivers (except
Windows), and the test suite is updated to handle user namespace daemon
rootgraph changes.

Replaced github.com/docker/libcontainer with
github.com/opencontainers/runc/libcontaier.
Also I moved AppArmor profile generation to docker.
Main idea of this update is to fix mounting cgroups inside containers.
After updating docker on CI we can even remove dind.

Export image/container metadata stored in graph driver. Right now 3 fields
DeviceId, DeviceSize and DeviceName are being exported from devicemapper.
Other graph drivers can export fields as they see fit.
This data can be used to mount the thin device outside of docker and tools
can look into image/container and do some kind of inspection.

daemon/volumes.go
This SetFileCon call made no sense, it was changing the labels of any
directory mounted into the containers SELinux label. If it came from me,
then I apologize since it is a huge bug.
The Volumes Mount code should optionally do this, but it should not always
happen, and should never happen on a --privileged container.
The change to
daemon/graphdriver/vfs/driver.go, is a simplification since this it not
a relabel, it is only a setting of the shared label for docker volumes.

There are a couple of drivers that swallow errors that may occur in
their Put() implementation.
This changes the signature of (*Driver).Put for all the drivers implemented.

The vfs storage driver currently shells out to the `cp` binary on the host
system to perform an 'archive' copy of the base image to a new directory.
The archive option preserves the modified time of the files which are created
but there was an issue where it was unable to preserve the modified time of
copied symbolic links on some host systems with an outdated version of `cp`.
This change no longer relies on the host system implementation and instead
utilizes the `CopyWithTar` function found in `pkg/archive` which is used
to copy from source to destination directory using a Tar archive, which
should correctly preserve file attributes.

Some graphdrivers are Differs and type assertions are made
in various places throughout the project. Differ offers some
convenience in generating/applying diffs of filesystem layers
but for most graphdrivers another code path is taken.
This patch brings all of the logic related to filesystem
diffs in one place, and simplifies the implementation of some
common types like Image, Daemon, and Container.

Since these will be shared between containers we want to label
them as svirt_sandbox_file_t:s0. That will allow multiple containers
to write to them.
Currently we are allowing container domains to read/write all content in
/var/lib/docker because of container volumes. This is a big security hole
in our SELinux story.
This patch will allow us to tighten up the security of docker containers.

This adds daemon/graphdriver/graphtest/graphtest which has a few
generic tests for all graph drivers, and then uses these
from the btrs, devicemapper and vfs backends.
I've not yet added the aufs backend, because i can't test that here
atm. It should work though.

This has every container using the docker daemon's pid for the processes
label so it does not work correctly.
