This removes the entire syncpipe package and replaces it with standard
operations on the pipes. The syncpipe type just never felt right and
probably should not have been there.

This is to support being able to DNAT/MASQ traffic from a container back into itself (dotcloud/docker#4442)

We need the ability when using --ipc container:ID to match the SELinux label of the
container that the new container is sharing a label with.
Also add the ability to get the option to disable SELinux labeling for a container.

Some workloads rely on IPC for communications with other processes. We
would like to split workloads between two container but still allow them
to communicate though shared IPC.
This patch allows us to mimic the --net code to allow --ipc=host to not split off
the IPC Namespace. ipc=container:CONTAINERID to share ipc between containers

Fixed getDeviceNodes() so it won't add /dev/console to the device node
list.
This fixes an issue where containers wouldn't start if
/dev/console is a pts (which is the case when running docker inside
docker), because devpts inodes are special and cannot be created with
mknod: attempting to open the result of doing so will return EIO.
Since later libcontainer would attempt to open the file to mount --bind
over it and fail because of the EIO error, the container wouldn't start
if the /dev/console was a pts, which is the case inside a docker
that was started from a pts.
getDeviceNodes() already filters pts so this change is consistent
with the current behavior.

Currently github.com/docker/libcontainer/cgroups/fs.GetStats does not provide the following metrics:
blkio.io_wait_time, blkio.io_service_time, blkio.io_merged, and blkio.time.
This commits add these four metrics. The descriptions of the metrics are here: https://www.kernel.org/doc/Documentation/cgroups/blkio-controller.txt.
It also modifies blkio_test and stats_util_test to ensure that the metrics are parsed.

We need to do this because it's a big dep. While we remove this
recursive dep this is the best that we can do right now.

For our work on adding dynamic device support to Docker we needed to be
able to call this to update the list of allowed devices. This works for
both systemd and fs based cgroups implementations.
