MST: split up patch
Sometimes we need to pass ranges around, add a
handy structure for this purpose.
Note: memory.c defines its own concept of AddrRange structure for
working with 128 addresses. It's necessary there for doing range math.
This is not needed for most users: struct Range is
much simpler, and is only used for passing the range around.
