Use a dedicated copy function to copy dsfs.

Previously we were duplicating the contents of a dsf using straight-up
memcpy. Now there's a dsf_copy function wrapping the same memcpy.

For the moment, this still has to take a size parameter, because the
size isn't stored inside the dsf itself. But once we make a proper
data type, it will be.
