de033f56c0 mpsc_queue: Add module.
This is a simple multi-producer, single-consumer queue.  The intended use case
is in the HPA, as we begin supporting hpdatas that move between hpa_shards.  We
take just a single CAS as the cost to send a message (or a batch of messages) in
the low-contention case, and lock-freedom lets us avoid some lock-ordering
issues.
