IMO, there is no "standard" intrusive pointer. The variations are (at
least):

* type of count: public variable, accessor functions, base class;
* name of count/accessors (addref, AddRef, addRef, attach);
* initial value of the reference count (zero or one.)
* delete in the pointer or self-delete in release.
