[boost] [detail] Added copyright to limits.hpp & endian.hpp

In an attempt to fix inspect failures I have added a boost license & copyright to the following files: <http://boost.cvs.sourceforge.net/boost/boost/boost/detail/limits.hpp?r1=1.26&r2=1.27> <http://boost.cvs.sourceforge.net/boost/boost/boost/detail/endian.hpp?r1=1.5&r2=1.6> The copyright is attributed to John because he seems to have made most of the changes to the Silicon Graphics original. If anybody feels that these changes are factually or legally wrong, please let me know. Thanks, -- Andreas Huber When replying by private email, please remove the words spam and trap from the address shown in the header.
