MDEV-162 Enhanced semisync replication
Implement --semi-sync-master-wait-point=AFTER_SYNC|AFTER_COMMIT.
When AFTER_SYNC, the semi-sync wait will be done earlier, before the storage
engine commit rather than after. This means that a transaction will not be
visible on the master until at least one slave has received it.
