Import binutils-2.10

- only the binutils package (no gdb here)
- don't import libiberty and texinfo, they are elsewhere
- remove all .info* generated files

+/* This package implements a partition of consecutive integers.  The
+   elements are partitioned into classes.  Each class is represented
+   by one of its elements, the canonical element, which is chosen
+   arbitrarily from elements in the class.  The principal operations
+   on a partition are FIND, which takes an element, determines its
+   class, and returns the canonical element for that class, and UNION,
+   which unites the two classes that contain two given elements into a
+   single class.
+
+   The list implementation used here provides constant-time finds.  By
+   storing the size of each class with the class's canonical element,
+   it is able to perform unions over all the classes in the partition
+   in O (N log N) time.  */
