Wrapper for const correct access via Smart pointer types.
zypp::RW_pointer<D,DTraits> stores a Smart pointer types of type DTraits::PtrType, which must be convertible into a D *. Pointer style access (via -> and *) offers a const D * in const a context, otherwise a D *. Thus RW_ means read/write, as you get a different type, dependent on whether you're allowed to read or write.
Forwarding access from an interface to an implemantation class, an RW_pointer prevents const interface methods from accidentally calling nonconst implementation methods.
The second template argument defaults to DTraits = rw_pointer::Shared<D> thus wraping a shared_ptr<D>. To wrap an intrusive_ptr<D> use rw_pointer::Intrusive<D>.
