Random comment the casual reader: Do you need to allow cases where src
and dest overlap?  IOW, can't you add restrict qualifiers, and if
necessary provide another function for unrestricted, potentially
overlapping areas?

The compiler should be able to optimize the restricted case nicely, I
would guess.
