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.

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.

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.

types of features inside docker.

Docker does not require RunIn API. Hence that API has been removed.
