This commit fixes a memory ordering bug in the futex implementation
(`Relaxed` -> `Release` on `downgrade`).
This commit also removes a badly written test that deadlocked and
replaces it with a more reasonable test based on an already-tested
`downgrade` test from the parking-lot crate.

In the same way that we expose SmallAtomic and SmallPrimitive to allow
Windows to use a value other than an AtomicU32 for its futex state, this
patch switches the primary futex state type from AtomicU32 to
futex::Atomic. The futex::Atomic type should be usable as an atomic
value with underlying primitive type equal to futex::Primitive.
This allows supporting the futex API on systems where the underlying
kernel futex implementation requires more state than simply an
AtomicU32.
All in-tree futex implementations simply define {Atomic,Primitive}
directly as {AtomicU32,u32}.
Reformat `use` declarations.2024-07-28T22:26:52+00:00Nicholas Nethercoten.nethercote@gmail.com2024-07-28T22:13:50+00:00urn:sha1:84ac80f1921afc243d71fd0caaa4f2838c294102
The previous commit updated `rustfmt.toml` appropriately. This commit is
the outcome of running `x fmt --all` with the new formatting options.

Many tiny changes to stdlib doc comments to make them consistent (for example
"Returns foo", rather than "Return foo", per RFC1574), adding missing periods, paragraph
breaks, backticks for monospace style, and other minor nits.
