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}.
