Change e2fsck to use a red/black tree in pass1b, to remove O(n**2) 
algorithms.  Makes e2fsck much, much faster in certain rare cases
where the filesystem is severely corrupted.

+	* dict.c, dict.h: New file from kazlib 1.20 which implements a
+		red-black tree
+	
+	* pass1b.c: Massive changes to take advantage of dict.c.  This
+		removes several O(n**2) algorithms from the rare case
+		where there are a large number of blocks claimed by
+		multiple inodes.
