Fix -Wnon-virtual-dtor compiler warnings.
This is done by explicitly adding a virtual dtor to interface classes,
since the cost is small given that there are already virtual functions.
The exceptions are for classes that have a Release() or Delete() method,
in which case it is non-virtual and protected to indicate that the virtual
class is never the deletion point.
