  cgmanager: don't stay connected

There are only a few times when we need to be connected to the
cgroup manager:

* when starting a container, from cgm_init until we've set cgroup limits
* when changing a cgroup setting (while running)
* when cleaning up (when shutting down)
* around the cgroup entering at attach

So only connect/disconnect the cgmanager socket on-demand as
needed.  This should have a few benefits.

1. Reduce the # open fds when many containers are running
2. if cgmanager is stopped and restarted, the container
   doesn't have to deal with the disconnection.

This is currently RFC.  There are a few issues outstanding:

1. the cgm_set and cgm_get may need to be made thread-safe.
2. a non-daemonized start which fails while cgm is connected,
will not disconnected.

  Log Message:
  -----------
  clone: don't ever mark the clone's rootfs as being the old, on disk

Otherwise an interrupted clone can lead to the original rootfs
being delete.

There is a period during lxcapi_clone during which we have written down
a temporary configuration file on disk, for the new container, using the
old rootfs. Interruption of clone doesn't allow us to do the cleanup we
do in error paths, so a subsequent lxc-destroy removes the old rootfs.

Fix this by doing the copy_storage as early as possible, and not
writing down the rootfs when we write down the temporary configuration
file.

(note - I tested this by putting a series of
'if (strcmp(newname, "u%d") == 0) exit(1)' inline to trigger
interruption between most blocks.  If someone has a good idea
for a generic way to regression-test this henceforth that'd be
great)

  -----------
  simpler shared rootfs handling

Only do the funky chroot_into_slave if / is in fact the rootfs.
Rootfs is a special blacklisted case for pivot_root.

If / is not rootfs but is shared, just mount / rslave.  We're
already in our own namespace.

This appears to solve the extra /proc/$$/mount entries in
containers and the host directories in lxc-attach which have
been plagueing at least fedora and arch.
