Allow AbstractTreeIterators to find out about StopWalkExceptions
If a tree iterator has overridden skip() to specially handle entries
which the TreeWalk has decided are not relevant then it might also
need to pay attention to a StopWalkException. The SWE is thrown out
of a filter and behaves much like skip, except it skips everything
else in the tree. This is used by PathFilterGroup to break out of
a walk once we know that no additional records could ever match.
