The rust null block driver is about to gain some additional modules. Rather
than pollute the current directory, move the driver to a subdirectory.

In the `module!` macro, the `author` field is currently of type `String`.
Since modules can have multiple authors, this limitation prevents
specifying more than one.
Add an `authors` field as `Option<Vec<String>>` to allow creating
modules with multiple authors, and change the documentation and all
current users to use it. Eventually, the single `author` field may
be removed.
[ The `modinfo` key needs to still be `author`; otherwise, tooling
may not work properly, e.g.:
$ modinfo --author samples/rust/rust_print.ko
Rust for Linux Contributors
I have also kept the original `author` field (undocumented), so
that we can drop it more easily in a kernel cycle or two.

Using `InPlaceModule` avoids an allocation and an indirection.

Now that we got the kernel `Box` type in place, convert all existing
`Box` users to make use of it.
