Corrupted Object and AAE

[martinsumner]

If an object is corrupted in a store - the AAE folds will keep crashing and the AAE trees will never be rebuilt.

It isn't possible to identify which object the fold crashes on, and there is no automated way of doing anything about the crash.

@s2hc-johan can you have a look at this please?

Does this look like it should solve the problem?

[martinsumner]

If a rebuild fold is interrupted by a riak stop ... then as the node shuts down a number of key reads will falsely report corruption, as the FoldObjectsFun will throw {error, badarg} when trying to get_index_n.

We may get an {error, badarg} due to corruption ... so shouldn't just not log. Either need to detect that riak is stopping, or add a disclaimer to ignore if shutting down. The log may otherwise cause unnecessary concern for operators.

On reflection, simply making the log clearer about context should be sufficient
