Somewhere between Boost 1.35.0 and 1.36.0, Boost.Serialization lost
the ability to (de-)serialize a pointer to a class with a protected or
private destructor. The problem is in
extended_type_info_typeid::destroy, which tries to delete a pointer
directly rather than using boost::serialization::access::destroy. This
is unfortunate, because it's breaking a use of the serialization
library in VTK.

The patch below fixes the problem and passes all regression tests.
Okay to commit to trunk and the 1.36.0 branch?
