Since there is no particular urgency to switch from transmute to
zerocopy, I think it makes sense to merge things in an order that limits
churn as much as possible.

This means the conversion should probably be done bottom-to-top,
starting with the bindings, then the types that embed them. For the
bindings, `#[derive(zerocopy_derive::most_traits)]` should be landing
soon [1] and I would like us to understand first whether that is
something we want to use with the bindings; if so, let's wait for it to
be available (unless there is a good reason to convert quickly) as each
change to `bindings.rs` is almost 200 LoCs.

Since Alistair maintains the tool generating the bindings [2], I think
it would make sense if he takes care of that part (bindings and anything
embedding them) as well.

There are also types in nova-core that do not depend on bindings at all;
for these I think it is fine to take the patches that have been already
submitted if they apply cleanly and build, as these are good
opportunities for first contributions. Nicolás was first to send
something for vbios/firmware [3] so I'd like to consider his v2 first
now that `-rc1` is tagged.

For the rest, I'm happy to merge anything that applies - small patches
limited to a single module should be easier to process and less likely
to conflict.
