Valentin Schneider d1e6d27738 rcu: Add a small-width RCU watching counter debug option
A later commit will reduce the size of the RCU watching counter to free up
some bits for another purpose. Paul suggested adding a config option to
test the extreme case where the counter is reduced to its minimum usable
width for rcutorture to poke at, so do that.

Make it only configurable under RCU_EXPERT. While at it, add a comment to
explain the layout of context_tracking->state.
