    extend the struct lxc_arguments

    This patch adds a private argument to extend the struct
    lxc_arguments. This is useful to develop custom lxc commands
    outside mainline lxc.

    lxc: introduce lxc_execute()

    This patch allows to create application containers with liblxc.so directly.

    Some code cleanups on the way:
    - separate ops for lxc_execute() and lxc_start(): the factorisation is wrong
      here as we may have specific things to do if we're running an application
      container. It deserves separate ops.
    - lxc_arguments_dup() is merged in the pre-exec operation: this is a first
      use for the execute op introduced just above. It's better to build the
      arguments to execvp() where they're really used.

    Otherwise we end up with a bad container fstab and a container
    that won't boot.  See

commit bc71b5c54fee6cd3f66d47c57bb54048d49f1429

    Don't list containers w/ active console sessions multiple times

    The lxc-ls shell script uses netstat -xa to get a listing of AF_UNIX
    sockets it then parses in order to determine the names of presently
    running containers. This is wrong because it will list the
    listening socket and all sockets created by accepting connections on
    that. This causes the script to display the names of containers with
    active lxc-console sessions 1 + n times, n being the number of active
    console sessions. The patch below fixes this by using netstat -xl
    instead which only displays the listening sockets.

    Accurately detect whether a system supports clone_children

    If multiple cgroups are mounted under /sys/fs/cgroup, then the
    original check ends up looking for /sys/fs/cgroup/cgroup.clone_children,
    which does not exist because that is just a tmpfs.

    So make sure to check an actual cgroupfs.

    Let sshd template work on ubuntu systems.

    /dev/shm is a symlink to /run/shm, so we need /run/shm
    to exist in the container rootfs.  Also, /dev/mqueue does
    not exist on the host, and can't be created by the container.
    But we don't really need it so ignore that.

    ubuntu template: disallow cap_sys_module (by popular demand)

    This isn't particularly reassuring, and will be moot with user
    namespaces, but as people are asking for it, turn off sys_module.
    While we're at it, turn off mac_admin and mac_override.
