The initial version of libbtrfsutil did not follow a unified naming scheme that's usually used for libraries like those provide by util-linux. Add aliases that are "btrfs_util_" + object + action + suffix. The library version changes to 1.3 but there's no new functionality, only the aliases added. New functions can be added in the future without possible confusion when the same action could apply to different objects. Issue: #574 Signed-off-by: David Sterba <dsterba@suse.com>
