paul luse 647b66a2ce Erasure Code Reconstructor 
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
