We've long been able to use these and they have a couple
great benefits:
1. Forces you to always access them atomically. With the pointer
variants it's completely valid to access the regular ol' int64/uint32
etc. without using the atomic.* methods. These wrappers don't provide
access to the underlying value so it forces correct usage always.
2. Conveys intent much better. Seeing the type be atomic.Int32 immediately
lets the reader know that this var will be used in a concurrent context,
and we no longer need comments like "this MUST be accessed atomically"
or similar.

Allow the api to stay at the same v1 go package name and keep using a
1.x version number. This indicates the API is still at 1.x and allows
sharing proto types with containerd 1.6 and 1.7 releases.

This makes use of pkg/sys's IgnoringEintr function
to clean up some of the redundant eintr loops we
had laying around.
