42964a36b7 Allow non-privileged containers to create device nodes. 
Such nodes could already be created by importing a tarball to a container; now
they can be created from within the container itself.

This gives non-privileged containers the mknod kernel capability, and modifies
their cgroup settings to allow creation of *any* node, not just whitelisted
ones.  Use of such nodes is still controlled by the existing cgroup whitelist.

5f846085d9 cgroups: Add systemd implementation of cgroups 
This implements cgroup.Apply() using the systemd apis.
We create a transient unit called "docker-$id.scope" that contains
the container processes. We also have a way to set unit specific
properties, currently only defining the Slice to put the
scope in.

cf568a7031 cgroups: Join groups by writing to cgroups.procs, not tasks 
cgroups.procs moves all the threads of the process, and "tasks" just
the one thread. I believe there is a risk that we move the main thread,
but then we accidentally fork off one of the other threads if the go
scheduler randomly switched to another thread. So, it seems safer (and
more correct) to use cgroups.procs.
