The series is separated from [1] to show the independency and compare
potential use cases easier.  This is the revocable core part.  Use cases
are in other series.

The 1st patch introduces the revocable which is an implementation of ideas
from the talk [2].

The 2nd and 3rd patches add test cases for revocable in KUnit and selftest.
