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.

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.

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.

This temp. expands the Exec method's signature but adds a more robust

provides a more accurate view with a single callback at this time.

libcontainer: Don't use UsetCloseOnExec, it is racy
...
We can't keep file descriptors without close-on-exec except with
syscall.ForkLock held, as otherwise they could leak by accident into
other children from forks in other threads.
Instead we just use Cmd.ExtraFiles which handles all this for us.
