[boost] Final ptr.hpp with sizeof(ptr<T>) = sizeof(T *) !

ptr<> is now acceptable & a _lot_ more simpler.  Ron Natalie answered a
question I was looking for a while ago: how do we get the block address of
the allocated virtual object?  With dynamic_cast<void *>()!!

Here is ptr.hpp & tree_traits.hpp simplified, and ptr_test.cpp as an
example:

tree_type is only of simple_tree (default) & complex_tree also...  no more
ambiguous_tree.
