dnet: fix strict aliasing warnings
Recent gcc doesn't like it when you cast char pointers to uint16_t
pointers and then dereference it. So use memcpy() instead and let
gcc take care of optimizing things away (when appropriate). This
should also fix alignment issues on arches where gcc packs the char
pointer tighter than 16bits.
