The IterateStorage and IterateAccounts methods are broken. They return
entries accounts which have been removed, and entries which are in
the cache are returned twice (from cache and backend).

So remove iterability from the cache and solve these problems.

In GetStorage() and get(), avoid potential concurrent duplicate backend
calls for the same entry by taking a write lock. This does increase
the time the cache is write locked.

Also avoid leaving the cache locked in early exit from the iterate
functions.
