[PATCH v2 0/4] Update thread safety markers

[Alice Ryhl <aliceryhl@google.com>]

In Rust, the `Send` and `Sync` traits are used to mark in what ways a
specific type is thread safe. In this patch series, I add some missing
thread safety markers and improve the documentation related to them.
This change will let you compile some code that would currently fail to
compile even though it doesn't actually violate any thread safety rules.

You can find a definition of what these marker traits mean at [1].

  rust: specify when `ARef` is thread safe
  rust: task: add `Send` marker to `Task`
