Michael Crosby fde0b7aa0d Refactor network and veth creation
Remove veth interfaces on the host if an error occurs.
Provide the host interface name, temporary peer interface name and the
name of the peer once it is inside the container's namespace in the
Network config.

Andrey Vagin d572094b75 new-api: execute a process inside an existing container
A new constructor function (like nsenter) is added in this patch.  This
function gets arguments from environment variables and its behaviour doesn't
depend on a command line arguments.

A program which calls factory.StartInitialization() must import the nsenter
package. It looks ugly, but I don't know another way how to enter into CT from
a go code.

Andrey Vagin 5ecd29c1f2 linux_container: fork an init process in a new set of namespaces
Use namespace.Exec() and namespace.Init() to execute processes in CT.

Now an init process is actually executed in a new container. This series
doesn't change code about creating containers, it only reworks code according
with new API.

Saied Kazemi ae81ea069f Add RootFs field to configuration options in libcontainer's Config
Since currently the container.json file does not include the pathname
to a container's root filesystem, we need to parse /proc/mounts which
is slow and error-prone.  This patch addresses this issue by adding a
new RootFs field.

Michael Crosby 70367b2cf3 Improve execin to support registering funcs
This also changes the functionality of the default exec in to just be an
existing func that is called than handles the implementation to exec a
user user's process inside the container.  This implements this
functionallity in nsinit but is a base for how we will be handling these
types of features inside docker.

Vishnu Kannan e5e40b6ef0 Docker 'runin' demands passing flags before 'nsenter' cli option.
Docker does not require RunIn API. Hence that API has been removed.
nsinit CLI has been modified to work around the nsenter changes.
