[PATCH 0/3] Rust 1.68.2 upgrade

[Miguel Ojeda]

This is the first upgrade to the Rust toolchain since the initial Rust
merge, from 1.62.0 to 1.68.2 (i.e. the latest).

Please see the last patch message for a long explanation of the upgrade,
the policy for future upgrades and some indications on how to easily
review this.

The series is based on `rust-next`.

Miguel Ojeda (3):
  rust: alloc: clarify what is the upstream version
  rust: arc: fix intra-doc link in `Arc<T>::init`
  rust: upgrade to Rust 1.68.2
