rcuscale: Add laziness and kfree tests

Browse source

This commit adds 2 tests to rcuscale.  The first one is a startup test
to check whether we are not too lazy or too hard working.  The second
one causes kfree_rcu() itself to use call_rcu() and checks memory
pressure. Testing indicates that the new call_rcu() keeps memory pressure
under control roughly as well as does kfree_rcu().
