Commit Message

Restrict `unsafe` blocks to single statements where possible. (#15806)

* Restrict `unsafe` blocks to single statements where possible.

To see which part of the code is unsafe, it is good to restrict `unsafe` blocks to the smallest sensible code unit. Clippy also has a feature to check this, `cargo clippy -- -W clippy::multiple_unsafe_ops_per_block`. This commit reduces some pretty large unsafe blocks to smaller ones to improve our code structure. Clippy actually flags _any_ snippet that has more than a single statement, but I left unsafe blocks in place where every single statement was actually unsafe.

* Reduce unsafe scopes further.

* More precise safety docs

* Update crates/cext/src/dag.rs
