This patch adds the erasure code reconstructor. It follows the
design of the replicator but:
- There is no notion of update() or update_deleted().
- There is a single job processor
- Jobs are processed partition by partition.
- At the end of processing a rebalanced or handoff partition, the
reconstructor will remove successfully reverted objects if any.
And various ssync changes such as the addition of reconstruct_fa()
function called from ssync_sender which performs the actual
reconstruction while sending the object to the receiver
