To add exception handlings: no problem.  But to support add_ref() and
counted_base can become questionnable.  Someone could help me draw the lines
if possible.  I must admit I have to work on another application at the same
time... I cannot fully concentrate on ptr.hpp.

I rewrote the license of mutable_ptr.hpp for those interested.  sort() is
working for lists but need to be tested for other containers.
