Changelog 20160104: only try if kernel supports cgns.

We'll probably want to make this configurable with a

Changelog 20160104: only try to unshare if /proc/self/ns/cgroup exists.

and continue without them if possible.  This allows an unpriv user
who only has a few cgroups he owns to still use lxc.

This patch only handles cgmanger - we need to handle this in cgfs too.

Linux for SPARC is a free community Linux distribution for SPARC hosted by Oracle. See : https://oss.oracle.com/projects/linux-sparc

While the distribution is based on Oracle Linux it does have some differences and since it's not actually Oracle Linux I decided to add a separate template rather than having the Oracle Linux template also support Linux for SPARC.

This patch adds the lxc-template for Linux for SPARC and it also adds Linux for SPARC in the configure.ac as a distribution target to build.

split bdev into modules: btrfs + rsync

Using

Signed-off-by: Christian Brauner <christian.brauner@mailbox.org>

The struct

	struct rsync_data {
