  cgfsng: next generation filesystem-backed cgroup implementation

This makes simplifying assumptions:  all usable cgroups must be
mounted under /sys/fs/cgroup/controller or /sys/fs/cgroup/contr1,contr2.

Currently this will only work with cgroup namespaces, because
lxc.mount.auto = cgroup is not implemented.  So cgfsng_ops_init()
returns NULL if cgroup namespaces are not enabled.

  cgfsng - remove the code checking whether devices cgroup lines are already done

We may need to revert this, but I *think* we no longer need this
with default configs.  The idea iirc was that if caller cannot
write to devices.allow (i.e. is in a user namespace), then ignore
permission failures if the cgroups are already sufficiently setup.

Note this is printing to stdout because it runs before logging is setup.
