Subject: [PATCH v1 00/28] Rust core additions

This patch series is the first batch of changes to upstream the rest
of the Rust support.

In this instance, all the facilities introduced are part of the "Rust
core". They do not interact with the C side in new major ways (no new
C types used; only `strlen`, `memchr`, additional error codes and some
more `printk` format strings).

After this series, `str.rs` and `print.rs` are in sync with downstream
and all remaining proc macros have been added. `error.rs` is fairly
complete too, though a few more `pub(crate)` features will come later
(to avoid leaving dead code in-between series).

Note that a few temporary `#[allow(dead_code)]` attributes are used in
order to have a bit more freedom organizing the patches while keeping
all of them buildable without warnings/errors, but at the end of the
series there is none remaining (of the temporary ones).

Virtually all the code has been in linux-next for months and was part
of the Rust patch series before the trimming down (i.e. up to v8).

Each patch has been built-tested on a Rust-enabled `defconfig` with
`CLIPPY=1` on the `all`, `rustfmtcheck`, `rustdoc` and `rusttest`
targets.
