This adds supports for a lock-less a non-shrinking growable array. You can use it to do reads using no locks, as long as your read-code can handle that during the read transaction the object can be modified by another writer (but it will not change size or be freed), and you can only trust the result once the transaction has finished successfully. This doesn't free things like RCU normally does, instead it pushes the memory on a free list that is reused for other atomic arrays.
