The virtd_lxc_t type provided by the default RHEL/CentOS/Oracle 6.5
policy is an unconfined_domain(), so it doesn't really enforce anything.
This change will provide a link in the documentation to an example
policy that does confine containers.

On more recent distributions with new enough policy, it is recommended
not to use this sample policy, but to use the types already available
on the system from /etc/selinux/targeted/contexts/lxc_contexts, ie:

process = "system_u:system_r:svirt_lxc_net_t:s0"
file = "system_u:object_r:svirt_sandbox_file_t:s0"

It's quite useful to be able to configure containers by specifying
environment variables, which init (or initscripts) can use to adjust the
container's operation.

This patch adds one new configuration parameter, `lxc.environment`, which
can be specified zero or more times to define env vars to set in the
container, like this:

    lxc.environment = APP_ENV=production
    lxc.environment = SYSLOG_SERVER=192.0.2.42
    lxc.environment = SOMETHING_FUNNY=platypus

Default operation is unchanged; if the user doesn't specify any
lxc.environment parameters, the container environment will be what it is
today ('container=lxc').

apparmor: Allow slave bind mounts

Without this, if the system uses shared subtrees by default (like systemd), you
get a large stream of

  lxc-start: Permission denied - Failed to make /<mountpoint> rslave
  lxc-start: Continuing...

with

  apparmor="DENIED" operation="mount" info="failed flags match" error=-13
  profile="/usr/bin/lxc-start" name="/" pid=17284 comm="lxc-start" flags="rw, slave"

and eventual failure plus a lot of leftover mounts in the host.

We detect whether ovs-vsctl is available.  If so, then we support
adding network interfaces to openvswitch bridges with it.

Note that with this patch, veths do not appear to be removed from the
openvswitch bridge.  This seems a bug in openvswitch, as the veths
in fact do disappear from the system.  If lxc is required to remove
the port from the bridge manually, that becomes more complicated
for unprivileged containers, as it would require a setuid-root
wrapper to be called at shutdown.

That mount hook predates the lxc.mount.auto = cgroup option.  So mention
that instead.

Perhaps we should simply drop the mountcgroup hook from the tree, but
I'm not doing that in this patch.

The netdev->priv is shared for the netdev types.  A bad config file
could mix configuration for different types, resulting in a bad
netdev->priv when starting or even destroying a container.  So sanity
check the netdev->type before setting a netdev->priv element.

Currently do_reboot_and_check() is decreasing timeout variable even if
it is set to -1, so running 'lxc-stop --reboot --timeout=-1 ...' will
exits immediately at end of second iteration of loop, without waiting
container reboot.
Also, there is no need to call gettimeofday if timeout is set to -1, so
these statements should be evaluated only when timeout is enabled.
