Add hard link support to gensquashfs and tar2sqfs
In libtar, set a special flag if the header is actually a hard link. In tar2sqfs, create a hard link node and skip the rest for hard links. Also refues to set the root attributes from a hard link, it may refere to a node that we have missed earlier, there is nothing else that we can do here. In fstree_from_file, add a "link" command for adding hard links. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
