[GIT PULL] Rust for 6.3

[GIT PULL] Rust for 6.3

[Miguel Ojeda]

Hi Linus,

A new set of features for the Rust support.

By the time you pick this, these commits will have been in linux-next
for quite a while. No conflicts expected. No changes to the C side.

Please pull for v6.3 -- thanks!

Cheers,
Miguel

----------------------------------------------------------------
Rust changes for v6.3

More core additions, getting closer to a point where the first Rust
modules can be upstreamed. The major ones being:

- Sync: new types 'Arc', 'ArcBorrow' and 'UniqueArc'.

- Types: new trait 'ForeignOwnable' and new type 'ScopeGuard'.

There is also a substantial removal in terms of lines:

- 'alloc' crate: remove the 'borrow' module (type 'Cow' and trait
  'ToOwned').
