ef5bfad321 Adding readOnly parameter to graphdriver Create method
Since the layer store was introduced, the level above the graphdriver
now differentiates between read/write and read-only layers.  This
distinction is useful for graphdrivers that need to take special steps
when creating a layer based on whether it is read-only or not.
Adding this parameter allows the graphdrivers to differentiate, which
in the case of the Windows graphdriver, removes our dependence on parsing
the id of the parent for "-init" in order to infer this information.

This will also set the stage for unblocking some of the layer store
unit tests in the next preview build of Windows.

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

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

b78e4216a2 Create extpoint for graphdrivers
Allows people to create out-of-process graphdrivers that can be used
with Docker.

Extensions must be started before Docker otherwise Docker will fail to
start.
