--------------------------------+-------------------------------------------
 The new traversal categories of Boost.Iterator should be used in std
 advance and std distance, but this is obviously not possible without the
 cooperation of compiler writers.

 The attached patch (against the trunk, rev. 39675) implements boost
 advance and boost distance that use the new iterator categories. It
 implements them within the utility library, since that library already
 contains the closely related next() and prior() function templates.
 Documentation and test cases are included.

 The patch also modifies next() and prior() to use boost advance(),
 although this change is a considerably higher risk than the addition of
 the new feature.
