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.

The hard links stores the target in the data.target field, canonicalizes the target and sets a sentinel mode. A second function is used to resolve link, i.e. replacing it with a direct pointer, setting another sentinel mode and increasing the targets link count. The post process function tries to resolve unresolved hard links and only allocates inode numbers for nodes that aren't hard links. If the target node of a hard link does not have an inode number yet, the two need to be swapped, since this is also the order in which they are serialized. The serialization function in libcommon simply has to skip hard link nodes and when writing directory entries, use the inode num/ref of the target node.
