COMP: Add support for newer versions of boost.

shared_dynamic_cast was deprecated and removed from newer versions of boost
as dynamic_pointer_cast provides the same functionality. Check at
configure time whether shared_dynamic_cast exists and if not, then
provide our own implementation that uses dynamic_pointer_cast.
