Before this, if `forceRemove` is set the container data will be removed
no matter what, including if there are issues with removing container
on-disk state (rw layer, container root).
In practice this causes a lot of issues with leaked data sitting on
disk that users are not able to clean up themselves.
This is particularly a problem while the `EBUSY` errors on remove are so
prevalent. So for now let's not keep this behavior.

Allow built images to be squash to scratch.
Squashing does not destroy any images or layers, and preserves the
build cache.
Introduce a new CLI argument --squash to docker build
Introduce a new param to the build API endpoint `squash`
Once the build is complete, docker creates a new image loading the diffs
from each layer into a single new layer and references all the parent's
layers.

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.

Instead of implementing refcounts at each graphdriver, implement this in
the layer package which is what the engine actually interacts with now.
This means interacting directly with the graphdriver is no longer
explicitly safe with regard to Get/Put calls being refcounted.
In addition, with the containerd, layers may still be mounted after
a daemon restart since we will no longer explicitly kill containers when
we shutdown or startup engine.
Because of this ref counts would need to be repopulated.

Instead of creating a "0.0" subdirectory and migrating graphroot
metadata into it when user namespaces are available in the daemon
(currently only in experimental), change the graphroot dir permissions
to only include the execute bit for "other" users.
This allows easy migration to and from user namespaces and will allow
easier integration of user namespace support into the master build.

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:
