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 3fc5455ec5 ecp5: 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.
