-store.fullsize-chunks=false breaks ingester hand-overs

[bboreham]

The feature implemented in #1044 results in handed-over chunks lacking the "footer" to add more values.

A simple way to work round the problem would be to reset the global flag before beginning a hand-over.

Maybe cleaner to add a "closed" flag to each chunk so it knows whether further writing is expected?

Closing this as we now use BigChunk as the default and it isn't a problem here anymore.

[bboreham]

The problem remains as stated. A reasonable step would be to remove this feature entirely.
