[boost] "Pending" files have no copyright

The following files in boost/pending have no copyright, there is a wider issue about what we should do with these files, but for now I'd just like to fix the licence issue. It looks like these are Jeremy Siek's work, is that correct? boost/pending/container_traits.hpp boost/pending/cstddef.hpp boost/pending/detail/disjoint_sets.hpp boost/pending/detail/property.hpp boost/pending/fenced_priority_queue.hpp boost/pending/fibonacci_heap.hpp boost/pending/property.hpp boost/pending/queue.hpp boost/pending/stringtok.hpp Thanks, John Maddock
