	If the hard link counter or the inode number counter overflow the maximum representable value (for SquashFS 16 bit and 32 bit respecitively), abort with an error message. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-12-23	Simplify hard link handling	David Oberhollenzer
	- For now, enforce that hard links don't point to a directories. - Instead of doing the swaping trickery, just reorder the flat list and hand out new inode numbers. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-12-22	Add basic support for handling and serializing hard links	David Oberhollenzer
	In libfstree, add a function to add a hard link to the fstree. 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.
