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.

Instead of having a file_info_t next pointer, requiring an up-cast
to tree_node_t all the time, simply add a "next_by_type" pointer to
the tree node itself, which can also be used for other purposes by
other node types and removes the need for up-casting.

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.
