Tonis Tiigi 4352da7803 Update daemon and docker core to use new content addressable storage
Add distribution package for managing pulls and pushes. This is based on
the old code in the graph package, with major changes to work with the
new image/layer model.

Add v1 migration code.

Update registry, api/*, and daemon packages to use the reference
package's types where applicable.

Update daemon package to use image/layer/tag stores instead of the graph
package

Dan Walsh 1716d497a4 Relabel BTRFS Content on container Creation
This change will allow us to run SELinux in a container with
BTRFS back end.  We continue to work on fixing the kernel/BTRFS
but this change will allow SELinux Security separation on BTRFS.

It basically relabels the content on container creation.

Just relabling -init directory in BTRFS use case. Everything looks like it
works. I don't believe tar/achive stores the SELinux labels, so we are good
as far as docker commit.

Tested Speed on startup with BTRFS on top of loopback directory. BTRFS
not on loopback should get even better perfomance on startup time.  The
more inodes inside of the container image will increase the relabel time.

This patch will give people who care more about security the option of
runnin BTRFS with SELinux.  Those who don't want to take the slow down
can disable SELinux either in individual containers or for all containers
by continuing to disable SELinux in the daemon.

Without relabel:

> time docker run --security-opt label:disable fedora echo test
test

real    0m0.918s
user    0m0.009s
sys    0m0.026s

With Relabel

test

real    0m1.942s
user    0m0.007s
sys    0m0.030s

Tonis Tiigi 504e67b867 Calculate hash based image IDs on pull
Generate a hash chain involving the image configuration, layer digests,
and parent image hashes. Use the digests to compute IDs for each image
in a manifest, instead of using the remotely specified IDs.

To avoid breaking users' caches, check for images already in the graph
under old IDs, and avoid repulling an image if the version on disk under
the legacy ID ends up with the same digest that was computed from the
manifest for that image.

When a calculated ID already exists in the graph but can't be verified,
continue trying SHA256(digest) until a suitable ID is found.

"save" and "load" are not changed to use a similar scheme. "load" will
preserve the IDs present in the tar file.

Phil Estes 442b45628e Add user namespace (mapping) support to the Docker engine
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.
