Don't let ln be a party to destroying user data.
* src/ln.c: Include "file-set.h", "hash.h" and "hash-triple.h".
(dest_set, DEST_INFO_INITIAL_CAPACITY): New globals.
(do_link): Refuse to remove a just-created link.
Record a name,dev,ino triple for each link we create.
(main): Initialize dest_set, if needed.
* tests/mv/childproof: Test for the above fix.
* NEWS: Document this.
