Subject: memcpy vs memmove: memmove correctly handles overlapping source and
 destination memory buffers, but is slower than memcpy in many
 implementations. When memory buffers don't overlap, memcpy may be more
 efficient.

The DS2 SDK is such an implementation, so change many memmoves into memcpys.
