Add support to hard links to CROMFS

Browse Source 
This will resolve numerous problems with the way that hard links, in particular "." and ".." are handled.  Instead of trying to fudge the stat flags, the correct implementation is to follow the hard link to the final link target node.  That is what must determine the attributes of the directory entry.
