This adds various Vec methods. Some of them are needed by Rust Binder,
and others are needed in other places. Each commit explains where it is
needed.

I'm not sure what we concluded on the set_len / dec_len changes, so I
don't depend on that series for now.

This series is based on top of Vec::truncate from
