There are few more things that could be cleaned up related to the coding style and other things, like explicitly specifying the abi style after "extern" (i.e. `extern "C" fn` instead of `extern fn`), but since those are configurable in rustfmt config, I'm not sure whether the config needs to be added or complying with the defaults should be the priority. But this was just

This adds very rough support for writing nbdkit plugins in Rust. This is not very idiomatic -- essentially we're handling the direct C calls from nbdkit in Rust. We have to use ‘unsafe’ in a few places because there's no way to tell the Rust code that nbdkit satisfies guarantees (eg. around thread safety, always returning leaked pointers back to the close function, always doing bounds

I originally meant to post only the "vector.h" patch, but then (independently) nbdkit wouldn't build. Hence the other (rust plugin) patch.
