forget/dont't memorize inode in to_link if st_nlink == 1

Might have caused data loss if inode number is reallocted to a file inside
the tree(s) being scanned.
Also saves a little bit of memory.

 ===========================
 
-* forget inode in to_link if link count is 1 before linking (might cause data
-  loss if inode is reallocted to a file inside the tree(s) being scanned)
 * more debug output when attributes mismatch in handle_file()
 * perhaps use hash_map, hash_multimap for better performance?
