I noticed that starting cgroups in a nested environment with the
mountcgroups hook is broken.  I'm going to change the cgroup code
in the next few days to:

1. instead of storing a single 'lxcgroup' for all subsystems, store
a struct per cgroup mount.
2. store the subsystem mountpont and the full path to the container's
cgroup file, rather than the '/proc/self/cgroup' value, which is
meaningless in nested context if we bind-mount the first level
container's cgroup entries.
3. probably add an entry to /etc/lxc/lxc.conf to optionally list
the cgroup mount points to respect.  That way people with funkier
setups - with extra cgroup mounts which lxc shouldn't touch - can
work around the funkiness.

It would be nice to get lxc-usernic into the tree, but I guess that
could wait until right after the alpha1, and go in along with the
core unprivileged containers code.
