Heavy Atom - convenient atomic pointer abstractions based on the atom crate

A hard fork of the atom crate which fixes some soundness issues and adds (requiring nightly features) const-initializers for Atom and AtomSetOnce.

lib.rs:

no_std port of the atom crate.

Notable changes:

• Atomic orderings fixed w.r.t. atom operations; Relaxed should never be allowed in the first place.
• Atom::empty() and AtomSetOnce::empty() are allowed to be const (requires the const_fn_fn_ptr_basics feature. This crate requires nightly rust, 1.58 up.)
