POC consistency check (DO NOT MERGE)

[nicktindall]

This implements a prototype approach for detecting and correcting partial updates that can occur as a result of an abrupt termination

Summary

If we acquire a write lock and writeInProgress is true it means the last lock holder did not complete the write, we then do a scan of the roll cycle to ensure the writePositionAndSequence table store header and index is consistent with the roll cycle state.

If we knew when the write lock was force-acquired we could probably do away with the writeInProgress flag, as a lingering write lock is a good indication that a consistency check is required.
