cgroups: Introduce lxc.cgroup.dir.monitor.pivot - fixes cgroup removal on termination

lxccontainer: fix lxc_config_item_is_supported

Enable lxc-attach to set the SELinux context that the user will end up
in when attaching to a container (This can be used to overwrite the
context set in the config file). If the option is not used, behavior
will be as before

Use exact match instead of longest prefix match
to check whether a config item is supported.
Signed-off-by: Ruben Jenster <r.jenster@drachenfels.de>

On termination lxc may fail to remove either lxc.cgroup.dir or lxc.cgroup.dir.monitor,
because the monitor process may still be a member of either of these cgroups.
The pivot cgroup should not be a member (subpath) of any other container cgroup (dir).
because only empty cgroups can be removed.

conf: account for early return when sending devpts fd

Signed-off-by: Christian Brauner <christian.brauner@ubuntu.com>

conf: always send response to parent waiting for devptfs_fd

When no devpts devices are requested we used to return early but did not send a
response to the parent. This is a problem because the parent will be waiting
for a devpts fd to be sent. Make sure to always send a response.
