Because the dir_entry_t also has a flag for had links, the regular
node and hard-link node interface can be unified. This simplifies
the users of libfstree (gensquashfs, tar2sqfs) since we can simply
hose the entries from an iterator directly into the tree.

Instead of adding special sentinel modes, simply treat hard links as
special case of symlinks, setting a flag to indicate that it is a
hard link and another flag to indicate that it has been resolved.

Use the next_by_type pointer to create a list of all unresolved
hard links and iterate over that list for link resolution.

The single boolean created_implicitly can be replaced with a general
purpose flag field. The "children" pointer can then be hoisted directly
into the data union of tree_node_t.

We do not allow hard links to directories, so we can toss the special
case handling code for that. The visited mechanism was pointless
anyway, because we don't even descend down hard links in the recursive
tree handling functions.

For some reason, the recursive hardlink resolution ended up in post
process, calling into the non recrusive one in hardlink.c that wasn't
used elsewhere.
