Chirantan Ekbote e7d1221c9d Make VolatileSlice ABI-compatible with iovec
Change VolatileSlice so that it is ABI-compatible with iovec.  This
allows us to directly pass in a VolatileSlice for a C function that
expects an iovec without having to create temporaries that convert from
one to the other.

Also change all the parameters from u64 to usize.  It's not possible to
address more memory than fits into a usize so having u64 here didn't
really provide much benefit and led to a lot of tedious casting back and
forth all over the place.

BUG=none
TEST=unit tests
