[Libvir] [PATCH 2/2] lxc: Shutdown and destroy container

This is a repost of the shutdown and destroy container support. Changes in this version: * Moved state changes to after the signal is successfully sent rather than restoring if it failed. * Signal handling in lxc_container goes away since the tty forwarding process is no longer the container root process. * Since the tty forwarding process is now outside the container, we have to kill and wait for it in the destroy.
