henrik.lundin 46ba49c622 Let PacketSource::NextPacket() return an std::unique_ptr
The return type of PacketSource::NextPacket() is changed from a naked
pointer to an std::uniqe_ptr. The interface contract was and still is
that the ownership is passed from the callee to the caller, but a
unique_ptr makes this explicit.
