spaceman: move inodes with hardlinks

When a inode to be moved to a different AG has multiple hard links,
we need to "move" all the hard links, too. To do this, we need to
create temporary hardlinks to the new file, and then use rename
exchange to swap all the hardlinks that point to the old inode
with new hardlinks that point to the new inode.

We already know that an inode has hard links via the path discovery,
and we can check it against the link count that is reported for the
inode before we start building the link farm.
