[PATCH 1/3] rust: enable `raw_ref_op` feature

[PATCH 1/3] rust: enable `raw_ref_op` feature

[Antonio Hickey]

Since Rust 1.82.0 the `raw_ref_op` feature is stable.

By enabling this feature we can use `&raw place` and `&raw mut place`
instead of using `addr_of!(place)` and `addr_of_mut!(place)` macros.

This will allow us to reduce macro complexity, and improve consistency
with existing reference syntax as `&raw`, `&raw mut` is very similar to
`&`, `&mut` making it fit more naturally with other existing code.

Hi Antonio,

Maybe we want a cover letter for this patchset? "--cover-letter" if
you're using "git send-email".

Typo in email (and that email may not be the one Benno wants).

One more thing, it has to be `&raw const` instead of `&raw`, I missed
that in the original issue, sorry!

This also needs to be fixed in the other two patches.

[PATCH v2 2/3] rust: clippy: disable `addr_of!`, `addr_of_mut!` macros

[Antonio Hickey]

With the `raw_ref_op` feature enabled we no longer want to
allow use of `addr_of!` and `addr_of_mut!` macros.

We instead want to use `&raw const` and `&raw mut` to get raw
pointers to a place.

This patch still needs to be done *after* the third one in order to
avoid warnings (since you're removing the usages of `addr_of[_mut]!` in
the next patch).

[PATCH v2 3/3] rust: replace `addr_of[_mut]!` with `&raw [const | mut]`

[Antonio Hickey]

Replacing all occurrences of `addr_of!(place)` with `&raw const place`, and
all occurrences of `addr_of_mut!(place)` with `&raw mut place`.

Utilizing the new feature will allow us to reduce macro complexity, and
improve consistency with existing reference syntax as `&raw const`, `&raw mut`
is very similar to `&`, `&mut` making it fit more naturally with other
existing code than the previously used macros.

[PATCH 2/3] rust: clippy: disable `addr_of!` and `addr_of_mut` macros

[Antonio Hickey]

With the `raw_ref_op` feature enabled we no longer want to
allow use of `addr_of!` and `addr_of_mut!` macros.

We instead want to use `&raw` and `&raw mut` to get raw
pointers to a place.

[PATCH 3/3] rust: replace `addr_of[_mut]!` with `&raw [mut]`

[Antonio Hickey]

Replacing all occurrences of `addr_of!(place)` with `&raw place`, and
all occurrences of `addr_of_mut!(place)` with `&raw mut place`.

Utilizing the new feature will allow us to reduce macro complexity, and
improve consistency with existing reference syntax as `&raw`, `&raw mut`
is very similar to `&`, `&mut` making it fit more naturally with other
existing code.

Depends on: Patch 1/3 0001-rust-enable-raw_ref_op-feature.patch
