D. Shah b87ab0ee9d Make RelSlice uncopyable 
Signed-off-by: D. Shah <dave@ds0.me>

D. Shah 75ee2fc4e6 Move RelPtr/RelSlice out of arches into common 
The bba approach seems widely used enough that it's reasonable for this
to become part of common code.

D. Shah e049d5f2fc nexus: Switch from RelPtr to RelSlice 
This replaces RelPtrs and a separate length field with a Rust-style
slice containing both a pointer and a length; with bounds checking
always enforced.

Thus iterating over these structures is both cleaner and safer.
