Linux futex-based implementations of [`Mutex`], [`RwLock`], [`Condvar`],

[`Once`], and [`OnceLock`], as well as [`RawMutex`], [`RawRwLock`], and

[`RawCondvar`], derived from the futex code in std, factored out to a

standalone `no_std` crate using [`rustix`] to do the futex and [`lock_api`] to

provide most of the public `Mutex` and `RwLock` API.

`lock_api` does not support poisoning, so support for poisoning is omitted.

In this library, `Condvar`, `RawCondvar`, `RawMutex`, and `Once` are guaranteed

to be `repr(transparent)` wrappers around a single `AtomicU32`. `RawRwLock` is

guaranteed to be a `repr(C)` wrapper around two `AtomicU32`s. The contents of

these `AtomicU32`s are not documented, except that all these types'

`const fn new()` and `INIT` are guaranteed to initialize them to all zeros.
