Michael Crosby 60e4276f5a Integrate new structure into docker's native driver
This duplicates some of the Exec code but I think it it worth it because
the native driver is more straight forward and does not have the
complexity have handling the type issues for now.

Michael Crosby f110401437 Remove statewriter interface, export more libcontainer funcs
This temp. expands the Exec method's signature but adds a more robust
way to know when the container's process is actually released and begins
to run.  The network interfaces are not guaranteed to be up yet but this
provides a more accurate view with a single callback at this time.

Alexander Larsson 7f7d8419a7 cgroups: Splity out Apply/Cleanup to separate file/interface
This leaves only the generic cgroup helper functions in cgroups.go and
will allow easy implementations of other cgroup managers.

This also wires up the call to Cleanup the cgroup which was missing
before.

Alexander Larsson 5c9b28db18 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.

This fixes https://github.com/dotcloud/docker/issues/4493

This is a minimal version of raw cgroup support for libcontainer.
It has only enough for what docker needs, and it has no support
